2 2 PowerFlex DC Drive - Frame A Pulse Transformer Circuit Board What You Need to Do To install the Pulse Transformer board: Step 1: Step 2: Step 3: Step 4: Step 5: Step 6: Step 7: Step 8: Remove power from the drive Remove the protective covers Remove the Control EMI shield and Control board Remove the Pulse Transformer and Switching Power Supply boards Configure the new Pulse Transformer board Install the new Pulse Transformer board and existing Switching Power Supply board Install the Control EMI Shield and Control board Replace the protective covers and document the change Step 1: Remove Power from the Drive ATTENTION: Remove power before making or breaking cable connections. When you remove or insert a cable connector with power applied, an electrical arc may occur. An electrical arc 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. Remove and lock-out all incoming power to the drive. L1 L2 L3 I O
