Earthing/Safety Details
Grounding
Permanent earthing is mandatory on all units because the earth leakage current exceeds 3.5mA
ac/10mA dc under normal operating conditions. Permanent earthing can be made in two ways:
1.
By using a copper conductor of at least 10mm² cross-sectional area.
2.
By using a second conductor, through separate terminals electrically parallel to the
protective conductor.
Note:
Each conductor itself must meet the local requirements for a protective earth
conductor.
Input Supply Details
(TN) and (IT)
Units with or without external filters are suitable for use on earth referenced (TN) supplies, but
units used with a filter are not recommended for non-earth referenced (IT) supplies..
Earth Leakage Current
>50mA (all models)
