Connecting the interface terminals
Connecting the interface terminals of several cabinets
If several cabinets are set up as one unit, the interface terminals of the cabinets must be
connected with each other.
Depending on the design of the cabinet, sockets for connecting the interfaces are located on
the left-hand side (viewed from the front), below or above. The connectors are provided at the
same position on the other cabinet.

Ensuring cooling air
The cooling air for the power unit is drawn in from the front through the ventilation grilles in the
cabinet doors. The heated air is sucked out of the cabinet by the fans mounted on top of the unit.
Make sure that the air that is supplied is free of dust or any other electrically conductive
material. Avoid cool air as this could cause condensation.
