5.2 Internal Connections in the Event of Control Cabinets Being Supplied
Separately
Inadequately qualified and untrained skilled personnel
can damage the system!
This can cause considerable damage to equipment.
Only qualified skilled personnel trained by the manu-
facturer may establish the internal connections of the
individual control cabinets (if they are supplied sepa-
rately).
All the cables for establishing electrical connections between the
individual control cabinets feature end-of-wire markings. This
means that they can be connected safely to the correct terminals.
The cables may only be connected at the designated connection
points.
Where possible, coded connectors ensure that plug connections
cannot be reversed.
The power lines must be tightened with the required torque to es-
tablish a reliable electrical connection (Table 1).
Unconnected protective earth conductors (PE) can
damage the system!
This can cause considerable damage to equipment.
Connect the protective earth conductor (PE) of the AC
control cabinet to the earth bar.
The cables are connected as follows:
Open the control cabinet door.
Remove the connection cover from the connection terminals.
Open the partition plates in the floor of the cabinet.
Insert the cables to be connected from below.
Fix the cables to the respective connections by securing the
cable lugs using an open-ended spanner.
Secure the protective earth conductors (PE) to the designated
unit frames.
Secure the cables on the cable clamp rail to provide strain re-
lief.
Check to ensure that the cables are secured correctly and
tighten the fixing bolts if necessary.
