Step 1: Removing 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.
