Safety Precautions
Installing the
Communication Adapter
Module in the Drive Follow these steps to install a communication adapter module:
1. Remove and lock-out all incoming power to the drive.
2. Disconnect the DPI cable from the HIM on the drive.
ATTENTION: Only qualified personnel familiar with drives, power products and
associated machinery should plan or implement the installation, start-up,
configuration and subsequent maintenance of the system. Failure to comply
may result in personal injury and/or equipment damage.
ATTENTION: To avoid an electric shock hazard, ensure that all power to the drive
has been removed before performing the following.
ATTENTION: This drive 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, reference A-B publication 8000-4.5.2, “Guarding Against
Electrostatic Damage” or any other applicable ESD protection handbook.
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.
