Notes:
Control transformer must be properly connected for line voltage (see transformer nameplate).
Do not apply voltage to LCM terminals 12 and 13. Dry contact type only.
Motor must be connected before power is applied. Otherwise, the shunt trip will will trip the motor circuit
protector.
Tachometer is only required when LCM is used in Tach Feedback mode.
Motor circuit protector and this circuit are not provided with the non−combination starters and fuse disconnect
versions.
