Notes:
1. Metal conduit should be used. Connect conduits so the use of Load
Reactor or RC Device does not interrupt EMI/RFI shielding.
2. See Line/Load Reactors described previously in this section.
3. Use same gauge wire for Earth ground as for L1, L2 and L3.
Note 3
See recommended terminal tightening torques in Section 7.
M-Contactor If required by local codes or for safety reasons, an M-Contactor (motor circuit contactor)
may be installed. However, incorrect installation or failure of the M-contactor or wiring
may damage the control. If an M-Contactor is installed, the control must be disabled for
at least 20msec before the M-Contactor is opened or the control may be damaged.
M-Contactor connections are shown in Figure 3-6.
