Baldor MN1851 manual Motor Connections for UL, Motor Connections for CE

X1 Motor Connections Motor connections are shown in Figures 3-11 and 3-12.

It is important to connect the motor leads U, V and W correctly at the X1 connector of the control. Incorrect wiring can cause erratic operation including moves at peak force until the overcurrent limit trips. This will result in a display of “7” and a “6” on the monitor. If erratic movement of the motor occurs, turn off power immediately and check the connections of the motor, hall sensors and encoder.

	Notes:
Baldor	1. Metal conduit or shielded cable should be used. Connect
Control	conduits so the use of Load Reactor* or RC Device* does not
	interrupt EMI/RFI shielding.

2.Use same gauge wire for Earth ground as is used for L and N. (VDE (Germany) requires 10mm2 minimum, 6AWG).

	U	V		W			3.		Reference EMC wiring in Section 8.
Note 1								4.	Motor and encoder are phase sensitive. Connect only as
									instructed.
						Note 2			For three phase controls, this is labeled “PE”.

Note: For CE compliant installations, connect unused leads within the motor cable to “PE” on both ends of the cable.

M-ContactorIf 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 3-13.
