The heater prevents humidity condensation inside the cabinet when the drive is not
powered. The power output of the semiconductor-type heating elements depends on
the environmental temperature.

not needed by cutting the supply voltage off.
ACS800-07 frames n×R8i, ACS800-17 and ACS800-37: The drive switches the
