Step 1: Remove Power
from the Drive

ATTENTION: To avoid an electric shock hazard, verify that the voltage on
the bus capacitors has discharged before performing any work on the
drive. Measure the DC bus voltage at the +DC & –DC terminals of the
Power Terminal Block. 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. 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.
