Connection Of The Earthing Circuit; Busbar Connection - efacec NORMAFIX Instructions Manual

8.6 Connection of the earthing circuit

All NORMAFIX components (bars, cables connections, fuses, etc.) are interconnected and
connected to the earth by the same copper circuit.
(*) – Points of connection of the busbar circuit common ground
Tighten the copper bars of the circuit ground to ensure continuity.
Tighten the M8H nuts with 0.9 daNm binary.
In the cell at the edge of the frame, turn the general
collector to the protective earth of the installation
through a copper conductor of 50 mm², M8H bolt,
washer and nut (binary 1.9 daNm)

8.7 Busbar connection

It is not necessary to prepare the contact surfaces (eventually, a simple dust cleaning).
However, if the panels have been stored for a long time, check the contacts for oxidation.
Starting at a switchboard end and always at the rear phase L1.
To access the bus it is necessary to remove the access panels (top of the panel).
