Electrical connection
The electrical connection of the device should be performed in accordance with VDE
0/100 and the TAB of the responsible EVU.
The expert verification before commissioning should determine that the required
protective measures are available.
The power connection is done using a Harting plug.
If the device is connected to a three-phase mains, the rotating field and the rotation
direction of the pump and ventilator motors should be checked. If necessary, the
rotation direction should be corrected by exchanging two outside wires.
The device connection should occur with a right hand rotation field.
ONLY FOR SPECIAL VOLTAGES
If a power transformer is built into the device, the mains connection is directly made on
the connections of the transformer. The protective sheet over the terminal block has to
be removed first.
