ATTENTION: To avoid an electric shock hazard, verify that
the voltage on the bus capacitors has discharged before servicing
the drive. Check the DC bus voltage at the Power Terminal
Block by measuring between the +DC and -DC terminals,
between the +DC terminal and the chassis, and between the -DC
terminal and the chassis. The voltage must be zero for all three
measurements.
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.
