What You Need to Do

To install the Pulse Transformer board:

❐ Step 1: Remove power from the drive

❐ Step 2: Remove the protective covers

❐ Step 3: Remove the existing Pulse Transformer board

❐ Step 4: Configure the new Pulse Transformer board

Step 1: Remove Power from

the Drive

1. Remove and lock-out all incoming power to 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.
