High-Voltage Connection to Rear of Panel (Optional)

Panels can be extended optionally by a rear cable compartment (Figure 67). In this case the cable connection can be done from top or from bottom.

This rear connection compartment permits connection to high voltage behind the panel. The variants of the cable connection options (depending on the rated nominal current) correspond to the explanations in Overview of Cable Connection System.

The preassembled sheet metal housing of the rear cable compartment is screw-fastened to the panel on the construction site.

The current transformers are located in the rear cable compartment. The front earth bar has a connection to the rear into the rear cable compartment.
