Infeed from above (option M13), motor connection from above (option M78)

Cable Entry from Above
With options M13 and M78, the cabinet unit is equipped with an additional hood. The
connection straps for the power cables, the clamping bar for mechanically securing the
cables, an EMC shield bus, and a PE busbar are located within the hood.
The hood adds an extra 405 mm to the cabinet height. The busbars for connection from
above are fully mounted when the system is delivered. For transport reasons, the hoods are
delivered separately and must be mounted on site. With options M23, M43 and M54, plastic
ventilation grilles and filter mats are also supplied.
A 5 mm aluminum mounting plate (with no holes) is fitted in the roof of the cover for feeding
in the cables. Depending on the number of cables and the cross-sections used, holes for
attaching cable glands for feeding in the cables must be drilled in this mounting plate on site.
Note
The control cables and optional brake resistors are connected as before from below.
Attaching the Hood
1. Remove the crane transport assembly (if fitted).
2. Options M43 and M54 only:
Use the sealing tape provided to attach the contact surfaces of the hood to the top of the
cabinet.
3. Fit the hood to the roof of the cabinet at the positions specified (fixing points for the crane
transport assembly).
4. To secure the power cables, remove the front panel of the hood.
