Cable Trays and Conduit
If cable trays or large conduits are used, see the guidelines in Wiring and
Grounding Guidelines for Pulse Width Modulated (PWM) AC Drives,
publication DRIVES-IN001 .
Select and Verify Control Transformer Voltage
The control transformer in the AFE is used to match the input AC line voltage
of the AFE in an IP21 Rittal enclosure to the 230V control voltage.
Verify that the control voltage is set appropriately for the supplied AC line
voltage. If necessary, use this procedure to change the control voltage.

ATTENTION: To avoid a possible shock hazard that is caused by induced
voltages, unused wires in the conduit must be grounded at both ends. For the
same reason, if a drive that shares a conduit is being serviced or installed, all
drives that use this conduit must be disabled. Disable the drives to help
minimize the possible shock hazard from ‘cross coupled’ motor leads.
