Cable Entry 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
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
• Remove the crane transport assembly (if fitted).
• For option M54 too:
Secure the contact surfaces of the hood on top of the cabinet using the sealing
tape provided.
• Fit the hood to the roof of the cabinet at the positions specified (fixing points for
the crane transport assembly).
• To secure the power cables, remove the front panel of the hood.
