The motor heater option provides the ability to control the supply for the motor anti-condensation heater. The 24 V DC external
supply is connected to terminal -XD1.1 in the lower part of the cabinet. When the drive is not in run state, the control relay -QAM
changes the external supply to the -XDM output terminals. When the drive is in run state, the control relay disconnects the external
supply to the motor heater. The function is disabled when MCB –FCN is open.
