Input and Output Terminals Table 4: Input and output terminals Terminal Function Explanation L Line input. Connect to a sine wave of Hz, V AC, single phase. N Neutral input 2. Use a double or triple core cable fo the input line. 3. Space the AC input line as far as possible from the DC output line. Frame ground terminal Connect with low impedance to ground line of equipment on which the power supply is mounted. V Output Terminal Stabilized output of V DC. V2 Output Terminal 2 Stabilized output of 2 or V DC. V3 Output Terminal 3 Stabilized output of 2, or V DC. G, G2 Ground Terminals G: ground terminal for V, G2: ground terminal for V2 and V3. G and G2 are internally interconnected. Proper Method of Operation To achieve the proper output voltage from each of the three output channels, the load currents must be within the minimum-maximum ratings. If the load current is below the minimum, use a pre-load. Output Current Limitation Each channel has its own built-in current limitation at approx. 0% of the rated currents. In the case of overloading, the circuit operates to avoid excessive current. After removal of the overload, the circuit automatically resets. Inrush Current All models feature inrush current limitation circuit by means of power thermistors. Switching the AC input on/off repeatedly in rapid succession (less than 2 minutes waiting) should be avoided. An appropriate AC switch for each model based on its specifications should be provided. Series or Parallel Connection The outputs cannot be operated in series or parallel connection with other type of sources. Edition / /9

5 Thermal Considerations The relation between the maximum allowed output power P o allwed, the temperature T A of the surrounding air and the mounting method is given in the: Installation Instruction. The percentage rates apply if the AC-DC converter is located in free, quasi-stationary air (convection cooling). The following figure shows the allowed output power of an AC-DC converter. For P o max values see: Type Survey and Key Data. The thermal conditions are influenced by input voltage, output current, airflow and temperature of surrounding components and surface. Caution: The installer must ensure that under all operating conditions T A remains within the limits stated in the table. P o /P o max T A [ C] Fig. 3 Maximum allowed output power versus ambient temperature Electromagnetic Compatibility (EMC) Electromagnetic Immunity A metal oxide VDR together with an input fuse and an input filter form an effective protection against high input transient voltages which typically occur in most installations, but especially in battery driven mobile applications.

8 Safety and Installation Instructions Installation Instructions Our AC-DC converters are components, intended exclusively for inclusion within other equipment by an industrial assembly operation or by professional installers. Installation must strictly follow the national safety regulations in compliance with the enclosure, mounting, creepage, clearance, casualty, markings and segregation requirements of the end-use application. See also: Technical Information: Installation and Application. Connection to the system shall be made via the terminal block at the rear side of the unit according to: Terminal Assignment. For safety reasons it is essential to connect the and ACG terminals with protective earth. See also: Safety of operator accessible output circuit. A fuse is built-in in the connection from the L terminal of the unit. Since this fuse is designed to protect the unit in case of an overcurrent and does not necessarily cover all customer needs, an external fuse suitable for the application and in compliance with the local requirements should be installed Mounting Methods Air Ample spacing in the wiring to the phase terminal L. A second fuse in the wiring to the neutral terminal N is needed if: Local requirements demand an individual fuse in each source line Neutral and earth impedance is high or undefined Phase and neutral of the mains are not defined or cannot be assigned to the corresponding terminals (L to phase and N to neutral) Important: Do not open the modules, or guarantee will be invalidated. Make sure that there is sufficient air flow possible for convection cooling. This should be verified by measuring the ambient temperature when the unit is installed and operated in the end-use application. The maximum specified ambient temperature T A max must not not be overriden, depending on output power and mounting method. See: Thermal Considerations and table Allowed output power by mounting method. Ample spacing Air Upper panel with good ventilation Air This surface in contact with chassis side or with convection cooling Case mounted on material with good heat conduction Fig. 8 Hoirizontal mounting Case side in contact with chassis Fig. 9 Vertical mounting Main chassis Case mounted on material with good heat conduction Standards and approvals The AC-DC converters correspond to class I equipment and are UL recognized according to UL 90, UL recognized for Canada to CAN/CSA 90 and LGA approved to IEC/EN 90 standards. The units have been evaluated for: Building in, Basic insulation between input and frame and double or reinforced insulation between input and output, based on their maximum input voltage. Operational insulation between output and frame, The use in a pollution degree 2 environment, Connecting the input to an overvoltage category II circuit if >0 V or an overvoltage category III circuit if 0 V. The AC-DC converters are subject to manufacturing surveillance in accordance with the above mentioned UL, CSA, EN and with ISO 900 standards. Isolation The electric strength test is performed as factory test in accordance with IEC/EN 90 and UL 90 and should not be repeated in the field. Power-One will not honour any guarantee claims resulting from electric strength field tests.

9 Safety of operator accessible output circuit If the output circuit of an AC-DC converter is operator accessible, it shall be an SELV circuit according to the IEC/EN 90 related safety standards The following table shows a possible installation configuration, compliance with which causes the output circuit of the AC-DC converter to be an SELV circuit according to IEC/ EN 90 up to a configured output voltage (sum of nominal voltages if in series or + configuration) of 44 V. However, it is the sole responsibility of the installer to assure the compliance with the relevant and applicable safety regulations. More information is given in: Technical Information: Safety.
