■ Overview
The neutral isolating valves are in the same position on all
terminals using 8WH4 plug-in technology.
A 10 mm x 3 mm busbar is used.

Installation instructions: to ensure that the neutral busbars are
securely mounted, the support brackets must be placed at the
beginning and end of each terminal strip (in the case of longer
terminal strips: every 20 cm).
