Table 11 - Recommended Shielded/Armored Wire for AFE in IP21 Rittal Enclosure
Cable Trays and Conduit
If cable trays or large conduits are to be used, refer to guidelines presented in
Wiring and Grounding Guidelines for Pulse Width Modulated (PWM) AC
Drives, publication DRIVES-IN001.
Selecting and Verifying 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, change the control voltage using this procedure.
1. Locate the X3 terminal block ( Figure 28 ).

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