PowerFlex 700L Frame 3A DC Bus Bar Conversion Kit

Transcription

1 Installation Instructions PowerFlex 700L Frame 3A DC Bus Bar Conversion Kit ATTENTION: To avoid an electric shock hazard, ensure that all power to the power module has been removed before performing any steps of these instructions. ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus capacitors has completely discharged before performing any work on the power module. After removing power to the power module, wait 5 minutes for the bus capacitors to discharge. Remove the lower front cover of the power module. Measure the DC bus voltage at the DC+ TESTPOINT and DC- TESTPOINT sockets on the front of the power module. The voltage must be zero. ATTENTION: HOT surfaces can cause severe burns. Do not touch the heatsink surface during operation of the power module. After disconnecting power allow time for cooling. ATTENTION: This power module contains ESD (Electrostatic Discharge) sensitive parts and assemblies. Static control precautions are required when installing, testing, servicing or repairing this assembly. Component damage may result if ESD control procedures are not followed. If you are not familiar with static control procedures, refer to Allen-Bradley publication , Guarding Against Electrostatic Damage or any other applicable ESD protection handbook.

After removing power to the power module, wait 5 minutes for the bus capacitors to discharge. Remove the lower front cover of the power module. Measure the DC bus voltage at the DC+ TESTPOINT and DC- TESTPOINT sockets on the front of the power module. The voltage must be zero. Remove power before making or breaking cable connections. When you remove or insert a cable connector with power applied, an electrical arc may occur, which can cause personal injury or property damage by: sending an erroneous signal to your system s field devices, causing unintended machine motion causing an explosion in a hazardous environment Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance. 1. Turn off and lock out input power. Wait 5 minutes. L1 L2 L3 I O 2. Verify that there is no voltage at the power module s input power terminals.

Set the cover aside to be reinstalled later. 4. Measure the DC bus voltage at the DC+ TESTPOINT and DC- TESTPOINT sockets on the front of the power module chassis. The voltage must be zero. Step 2: Removing the Top Cover 1. Remove the ten (10) M5 x 16 mm (0.63 in.) long Philips screws that hold the top cover to the power module chassis, and remove the top cover. Set the top cover and screws aside to be reinstalled later. Rear Shield 6X Front Shield 6X TOP Screw M5 X 16mm Long 10X Top Cover Chassis 2. Using the malleable hammer, apply force to the back side of the twelve (12) plastic rivets that secure the front and rear shields to the top cover, and remove them with pliers. Discard the shields and rivets.
