Safety Instructions WARNING! Before installing and using your inverter, please read the General Safety Instructions! 1. General Safety Instructions Do not expose the Inverter to high levels of moisture, rain, snow, spray, bilge, dust, sources of heat or sunlight. To reduce risk of hazard, do not cover or obstruct the ventilation openings. The Inverter uses exhaust fans for forced ventilation which will operate when the inverter reaches a certain temperature. Do not install the Inverter in a zero-clearance compartment. Overheating may result. To avoid a risk of fire and electronic shock, make sure the installed wiring and terminations are in good electrical condition and that all cables are not undersized. Do not operate the Inverter with damaged or substandard wiring. Keep the Inverter in a secure and safe place, out of the reach of children. Check the ON/OFF switch is in the OFF position before installation. To prevent electric shock, do not remove the cover. Dangerous voltages exist inside the unit even after it has been switched OFF. If a fuse blows, or protective device fails, parts of the Inverter still remain functional. There are no user serviceable parts inside. Only qualified personnel should carry out maintenance or service the device. -3-

4 2. Explosive Gas Precautions This equipment contains components that can produce electrical arcs or sparks. To prevent fire or explosion do not install in compartments containing batteries or flammable materials, or in locations that require ignition-protected equipment. This includes any space containing gasoline-powered machinery, fuel tanks, or joints, fittings, or other connections between components of the fuel system. 3. Precautions When Working With Lead-Acid Batteries If battery acid contacts skin or clothing, wash immediately with soap and water. If acid gets into eyes, immediately flood eyes with running cold water for at least 20 minutes and get medical attention immediately. NEVER smoke or allow a spark or flame in vicinity of batteries or an engine. Do not drop a metal tool on the battery. The resulting spark or short-circuit of the battery may cause an explosion. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. A lead-acid battery can produce short-circuit currents high enough to weld a ring or similar metal, causing a severe burn. 4.

5 1. Ventilation Openings Do not obstruct the ventilation openings; allow at least 25mm for airflow around all openings. 2. Battery terminals Only connect the Inverter to a 12VDC battery, battery bank or other 12VDC power source. (POS+) is Positive, (NEG-) is Negative. WARNING! Do not reverse the polarity of the input connections. Reverse polarity connection will blow internal fuses and may damage Inverter permanently. 3. Remote Control (Located on the side of the inverter) Connect remote control unit (supplied) as necessary. WARNING! Shock Hazard! Before proceeding, ensure the Inverter is NOT connected to any Batteries or DC Power Source. Do not connect the AC output Terminals of the Inverter to an incoming AC Power Sources such as the mains. G. Pre-Installation Information Before installing your Inverter, please make sure that you have appropriately-sized batteries with sufficient ampere-hour capacity. A battery that is too small will not allow the Inverter to perform to its full specification. H. Electrical Requirements The DC input voltage of the Inverter must be the same as the battery bank voltage. The DC cabling must be connected to the correct polarity terminals of the battery bank. Red (POS+) Positive, Black (NEG-) Negative). DO NOT extend the DC cable length to the Inverter unless you are prepared to increase the diameter of the cable. If this is necessary consult your supplier/ installer for advice. DO NOT connect AC power to the AC output of the Inverter: THIS WILL DAMAGE THE INVERTER. Between the Inverter and any generator / mains supply, it is essential you install a double-pole break-before-make changeover switch that switches both line and neutral AC power. DO NOT place the AC power cable and the 12VDC cable in the same cable duct. To prevent electrical shock, DO NOT operate the Inverter without connecting it to ground. Always disconnect the inverter when not in use. -5-

6 I. Installation Requirements 1. Where to install The Power Inverter should be installed in a location that meets the following requirements: Dry Do not expose the Inverter to high levels of moisture, rain, snow, spray or bilge fluids. Make sure the Inverter is not exposed to salt water vapour. Temperature Ambient air temperature should be between 0 Cand 40 C. Do not expose the Inverter to heat sources or direct sunlight. Safety Do not install in a battery compartment or other areas where flammable fumes may exist, such as fuel storage or engine compartments. Ventilation Allow at least 25mm of clearance around the inverter for airflow. Ensure the ventilation openings on the sides and bottom of the unit are not obstructed. The installation site should not be susceptible to temperatures in excess of 50 C. Dust-free Do not install the inverter in an environment where there is dust, wood particles or other filings/shavings present. These can pull into the unit blocking the cooling fans. Close to battery/batteries Avoid excessive cable lengths (Mount the inverter between one and two meters from the batteries) but do not install the inverter over or in the same compartment as batteries. Use the recommended wire lengths and sizes. Do not mount the inverter where it will be exposed to the gases produced by the battery or battery bank. These gases are very corrosive and prolonged exposure will damage the inverter. Wall-mount Inspection and operation of the Inverter is easier if the unit is mounted at a convenient height and the DC cables hang naturally out of the way. 2. Safety Grounding To prevent electrical shock, DO NOT operate the Inverter without connecting it to an appropriate ground V Models There is no connection made inside the Inverter from either of the line conductors (line or neutral) to the earth ground. WARNING! Operation of the inverter without a proper ground connection may result in an electrical safety hazard. Please read these instructions carefully before commencing installation. Installation should be performed by competent qualified installer as dangerous voltages can be present. Complete the following steps in the order shown: 4. Mounting Unpack the Inverter from the shipping container and inspect the unit for any obvious transit damage. Report any concerns immediately to your supplier. Mount the Inverter to a suitable surface, paying close attention to the mounting requirements previously mentioned in this manual. 5. AC Wiring Important: to satisfy warranty requirements and conditions, a qualified electrician must perform all AC wiring. -6-

7 6. DC Wiring IT IS ESSENTIAL that the battery bank voltage match the DC input voltage rating of the Inverter. Damage to the Inverter could result from improper voltage connections. A Battery Fuse must be installed between the batteries and the Inverter; appropriately sized Motor-Starting fuses or similar are recommended. Before making any connections ensure that the Inverter Power Switch is in the OFF position. WARNING! Do not operate the power inverter without connecting it to ground. Electrical shock hazard may result. The DC cables should be as short as possible (ideally, less than 3 metres) and large enough to handle the required DC current in accordance with electrical codes or regulations applicable to your installation. Cables that are not an adequate gauge ( ie too small in diameter) or are too long will cause decreased inverter performance such as: poor surge capability frequent low input voltage warnings shutdowns. J. Connection and Testing For a quick connection and performance check, please follow these guidelines: Note: The connection to the Negative (NEG-) terminal of the Inverter should be the last connection made. A spark when making this final connection is normal. Step 1: Unpack and inspect the Power Inverter for any damage. Step 2: Make sure the power switch in the OFF position. Step 3: Connect the DC Positive cable to the Positive (POS+) terminal on the battery. Next, connect the DC Positive cable to the Positive terminal on the Inverter (via the Battery Fuse). Make sure the connections are secure. WARNING! Make sure all the DC connections/ terminations are tight (torque to 9-10 ft-lbs, nm). Loose connections will overheat and could result in a fire hazard. Before proceeding further, recheck the cable you have just connected to the Positive terminal of Inverter, and to the Positive terminal of the battery or DC power source. -7-

8 Ï Ð CAUTION! Reversed polarity connections will blow a fuse and may permanently damage the Inverter. Damage caused by a reverse polarity connection is Not covered by warranty. Step 4: Connect the DC Negative cable to the Negative terminal of the Inverter. Next, connect the DC Negative cable to the Negative (NEG-) terminal on the battery or power source. Make sure the connections are secure. WARNING! You may observe a spark when you make this connection. Do not make this connection in the presence of flammable fumes. Explosion or fire may result. Step 5: Set the Inverter power switch to the ON position. Check the POWER and RUN/GREEN POWER LED indicators on the front panel of the Inverter are illuminated. If the LED is not illuminated, check your power source and the connections to Inverter. The other indicators should be off. Step 6: Set the Inverter power switch to the OFF position. The indicator lights may blink and the internal alarm may sound momentarily. This is normal. Step 7: Plug the AC test load into the AC receptacle on the front panel of the Inverter. Leave the AC test load switch in the OFF position. Step 8: Set Inverter power switch to the ON position and turn the test load ON. The Inverter should supply power to the test load. If you plan to measure the AC output voltage of the Inverter, a Digital Multi Meter with true RMS voltage capabilities must be used. K. Operation To operate the Inverter, turn it ON using the Power ON/OFF switch on the front panel. The Inverter is now ready to deliver AC power to your appliances/ loads. If you are operating several appliances/ loads from the Inverter, turn them ON separately after the Inverter has been switched ON. This will ensure that the Inverter does not have to deliver the starting currents for all loads at once and hence, minimizes the risk of a shutdown. 1. Controls and Indicators The power ON/OFF switch turns the control circuit in the Inverter ON and OFF. It does not disconnect DC power from the Inverter. The Inverter operates from an input voltage ranging from 10VDC to 16VDC for 12V models. 2. Over Voltage Indicator The over voltage indicator indicates that the Inverter has shut down because the protection circuits have sensed the DC input voltage is higher than that recommended for safe operation. -8-

9 3. Under Voltage Indicator The under voltage indicator indicates that the Inverter has shut down because the protection circuits have sensed the DC input voltage is lower than that recommended for safe operation. 4. Over Temp Indicator The over temp indicator indicates that the Inverter has shut down because the thermal protection circuits have sensed the Inverter has become overheated. The Inverter may overheat because it has been operated at power levels above its rating, or because it has been installed in a location which does not allow it to dissipate heat properly. The power inverter will restart automatically once it has cooled down. If the Inverter continues to shut down, reduce the load, and check the ambient temperature. 5. Overload Indicator The overload indicator indicates that the Inverter has shut down because its output circuit has been short circuited, or drastically overloaded. Switch the ON/OFF switch to OFF, correct the fault condition, and then switch the ON/OFF switch back to ON. L. Green Power Adjustment The Inverter features automatic load-sensing, which means it will wait in Standby Mode until an AC load is switched ON. When an AC load appears, the Inverter will immediately start. This feature conserves valuable battery energy as the Inverter uses only about 10% of normal power when in Standby Mode (Standby Mode is indicated by flashing GREEN indicator). The amount of AC power required to start the Inverter can be adjusted on the front panel. Follow the procedure below. Ensure the battery voltage is at the nominal 12V level. 1. Adjusting Load Sensitivity for Green Power Mode Turn OFF all AC loads, keeping the AC wiring connected to the Inverter AC output. Some loads such as TVs must be turned OFF at the power point as they can still represent a small load to the Inverter. Using a small screwdriver, adjust the black plastic trim pot located to the right of the over voltage indicator and to the left of the power switch. Turning this control fully clockwise will override the Standby circuit and keep the Inverter ON all the time. This could be used if you have a very small load that must stay ON at all times. Adjust the trim pot until the indicator is a steady GREEN; then turn the trim pot back a little until the indicator flashes GREEN. Allow 10 seconds between adjustments for stabilisation: clockwise decreases the sensitivity or threshold; counter-clockwise is increases the sensitivity or threshold. Note: the trim pot is extremely sensitive. When the indicator flashes GREEN, the Inverter is in Standby Mode. Turn ON the smallest AC load connected to the Inverter. The Inverter should now deliver 240VAC, and AC status indicator should be a steady GREEN. However, if the indicator is ORANGE the sensitivity must be increased by turning the control trim pot a little counter-clockwise. Now turn OFF the AC load. The indicator should return to flashing GREEN, indicating that the Inverter is in Standby Mode. If this does not occur, reduce sensitivity by turning the control trim pot a little clockwise and check again. M. Trouble Shooting: 1. AC Output Does Not Remain ON If Green Power Mode is being used, some AC loads may not be large enough to hold the Inverter ON. This condition is indicated by the Inverter turning OFF after every eight to ten seconds, then back ON again. The AC Status indicator will also be flashing ORANGE. There are two possible solutions: Increase the sensitivity of the inverter by turning the Standby control slightly counter-clockwise until the indicator is a steady GREEN; or Increase the amount of AC load on the Inverter. -9-

10 2. Over Temperature Shut Down Your inverter will safely provide the output power defined in the technical data section under the conditions specified. If the Inverter shuts down and indicates over temperature, it may be that you have exceeded one of the parameters. Check the following: Ensure the Inverter has adequate ventilation. Insufficient ventilation can severely restrict the power output of your Inverter as it does not allow proper heat dissipation. Ensure that the true power rating of your appliance (including power factor) is less than the output rating of your Inverter. 3. Shut Down When Trying to Start a Load A sudden surge in load, such as a motor starting, may cause the inverter to shut down. If this occurs: Ensure the battery voltage is within specifications when the device is trying to start. If the input voltage drops too low, you may need to increase the capacity of your batteries. Also check DC cables and terminations. If the battery voltage is ok when measured at the Inverter, then the Inverter AC output power rating may be too. 4. Overload Shut Down The overload indicator indicates that the Inverter has shut down. If this occurs: Ensure the output circuit is not short circuited, or drastically overloaded. Switch the ON/OFF switch to OFF, correct the fault condition, and then switch the ON/OFF switch back to ON. 5. Under Voltage Shut Down The under voltage indicator indicates that the Inverter has shut down because the protection circuits have sensed the DC input voltage is lower than that recommended for safe operation. If this occurs: Charge the battery. Check the battery voltage at the terminals of the Inverter is within specification. If the input voltage drops too low, you may need to increase the capacity of your batteries. Also check DC cables and terminations. 6. Over Voltage Shut Down The over voltage indicator indicates that the Inverter has shut down because the protection circuits have sensed the DC input voltage is higher than that recommended for safe operation. If this occurs: Check the DC power source or battery voltage at the terminals of the Inverter is within specification. 7. Television Interference Operation of the Inverter can interfere with television reception on some channels. If this occurs, the following steps may help alleviate the problem: Make sure that the chassis ground lug on the back of the Inverter is solidly connected to the ground system of your vehicle, boat or home. Make sure there is no oxidation or corrosion on any groumd terminations. Try not to operate high power loads with the Inverter while watching television. Make sure that the antenna feeding your television provides an adequate ( Snow free ) signal and that you are using high quality shielded cable between the antenna and the television. Move the television as far away from the Inverter as possible. Keep the cables between the battery and the Inverter as short as possible. Twist them together with about 6 to 9 twists per metre as this helps minimising radiated interference from the cables. -10-

11 WARNING! There are no user serviceable parts inside. Only qualified personnel should carry out maintenance or service the device. Do not open or disassemble the Inverter. Attempting to service the unit yourself may result in a risk of electrical shock or fire. N. Maintenance Very little maintenance is required to keep the Inverter operating properly. With the Inverter switched OFF, clean the exterior of the unit periodically with a slightly damp cloth to prevent accumulation of dust and dirt. At the same time, check and tighten all cable terminations on the DC input terminals. -11-
