The auxiliary supply terminal option provides an external voltage supply to the –XD1.1 terminal. The external supply must be short-
circuit protected. The power of the external supply depends on other selected cabinet options.

HIGH VOLTAGE
The mains disconnect switch does not disconnect the external voltage supply. Failure to disconnect the external voltage supply
before touching any components in the control compartment can result in death or serious injury.
Disconnect the external voltage supply.
Only qualified personnel must install, start up, and maintain the drive.

The auxiliary voltage transformer is an option fitted internally that allows for the supply to be tapped from the mains. For example, if
the enclosed drive is specified with a fused disconnect, the supply for the auxiliary voltage transformer is taken from between the
drive and the fused disconnect. This configuration allows the control voltage to be disconnected with the main switch.
The transformer has multiple tappings on the primary side for the standard range of voltages on which the drive operates. The fac-
tory default wiring connects to the highest voltage tapping on the primary side, and the trip settings for the -FC4 terminal is set
accordingly. The customer can change the tapping provided the correct voltage is applied and the thermal magnetic circuit breaker
is set accordingly.
