Up to 2 cables (plugs) can be connected per phase for 600-mm-wide panels and up to 3 cables
(plugs) per phase for 450-mm-wide panels.
After cable installation on the three phases, one arcing plate each must be mounted in the
cable compartment. In like manner, the associated floor plate of the pressure-resistant floor
cover must be mounted after each installed row of cable T-plugs (see page 97, "Mounting the
pressure-resistant floor cover").
NOTE!
The arcing plates in the cable compartment have been pre-assembled at the factory. For cable
installation, the arcing plates must be removed.
After cable installation, position the arcing plates as close as possible to the front in

accordance with the cable T-plugs used.
Do not exceed the distance of 10 mm to the cable T-plugs.

After installation, the arcing plates must not touch the cable T-plugs.

While installing the arcing plates, take care not to damage the cable T-plugs.
