Notes On Installing The Opencom 510 - Aastra OpenCom 510 User Manual

Installation
Earthing and Potential
For the purpose of potential equalisation, all conductive parts of the
OpenCom 510 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
2,5 mm (yellow/green).
OpenCom 510: 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 con-
ductor of the 230 V mains cables is connected to the circuit common and the tele-
phone earth line.
All metal parts of the communications system are mechanically and thus electri-
cally coupled in order to provide protection through the protective earth con-
ductor and the telephone earth line.
