Earthing/Safety Details

Each unit must be permanently earthed according to EN 50178.
Earthing
For permanent earthing, EN 50178 states that:
A cross-section conductor of at least 10mm² is required. This can be achieved either by using a single
conductor (PE) or by laying a second conductor though separate terminals (PE2 where provided) and
electrically in parallel.
Use a copper protective earth conductor of at least 10mm² minimum cross-section. These drives are fitted
with four permanent earthing points.
Conductors must be sized in accordance with Local Wiring Regulations which always take
precedence.
As a guide, refer to the Input Current for the drive given in the Electrical Ratings tables.
Input Supply
Drives without filters are suitable for earth referenced (TN) or non-earth referenced (IT) supplies.
Details External filters are available for use on earth referenced (TN) supplies only.
