Revision 11 • INSTALLATION AND OPERATING INSTRUCTIONS • NXPLUS C • 802-9081.9

16.6

Connecting auxiliary circuits

The circuit-breaker switchgear NXPLUS C is delivered with operating and control equipment as
ordered.

The operating and control equipment as well as the terminals in the switchgear are identified
in the same way as in the associated circuit diagrams.

If the low-voltage compartment is installed later, the connections of the auxiliary circuits are
completed on site.

Fig. 126: Auxiliary circuits in the 600 mm low-voltage compartment

Fig. 127: Auxiliary circuits in the 900 mm low-voltage compartment

Lay, fix and connect the external cables in accordance with the national standards and
specifications (conductor, shielding, earthing).

Fig. 128: Open the right-hand leaf of the 900 mm low-voltage compartment door (open the

left-hand leaf and undo two bolts on the right-hand leaf)
