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.
