Earthing and potential

Forum Gateway 560 must be connected to the protective earth conductor
(earth bus-bar of the building’s wiring system) by means of a solid or
stranded wire of at least 2,5 mm

(yellow/green).
Forum Gateway 560: Earthing arrangement
The metal screens of the subscriber and trunk cables must be connected to
the circuit common in the distributor or the patch field. The protective earth
conductor of the 230 V mains cables is connected to the circuit common and
the telephone earth line.
All metal parts of a Forum Gateway 560 are mechanically and thus
electrically coupled in order to provide protection through the protective
earth conductor and the telephone earth line.

when installation work on the system is interrupted or terminated. Unused
