E-8 Technical Specifications 590 Series DC Digital Drive
Earthing/Safety Details
Earthing 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 laid 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..
