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 -XDN 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.
