7.2.4 Auxiliary Voltage Transformer (-TA4)
The cooling module is equipped with an auxiliary voltage transformer by default. The auxiliary voltage transformer supplies a
24 V DC power supply that distributes power to the control circuits. The auxiliary voltage transformer is protected by a circuit break-
er on the primary side.
If the cooling module is equipped with a cabinet heater, the auxiliary voltage must be provided externally.
