Description
On options M13 and M78, the connection straps for the power cables, the clamping bar for
mechanically securing the cables, an EMC shield bus, and a protective ground busbar are
located within the tophat.
The busbars for connection from above are fully mounted when the system is delivered.
For transport reasons, the tophats are delivered separately and must be mounted on site.
With options M23, M43 and M54, plastic ventilation grilles and filter mats are also supplied.
Based on the number of cables and the cable cross-sections used, holes must be drilled for
attaching cable glands through which cables will be inserted.
