The cabinet heater option increases the inside temperature of the cabinet above the ambient temperature, preventing condensa-
tion in the cabinet. Each cabinet has 1 cabinet heater. The heater element is self regulating. The external supply is connected to
terminal -XD1.1. When the drive is not in run state, the control relay -QAM changes the supply to the output terminals (-XD4). When
the drive is in run state, the control relay disconnects the supply to the cabinet heater. The function is disabled when MCB –FCE is
open.
