Protective Earth (PE) Connections
The unit must be
permanently earthed
according to EN 50178 - see below. Protect the incoming mains
supply using a suitable fuse or circuit breaker (circuit breaker types RCD, ELCB, GFCI are not
recommended). Refer to Chapter 7: Circuit Breakers.
IMPORTANT
The drive is only suitable for earth referenced supplies (TN) when fitted with an internal filter.
External filters are available for use on TN and IT (non-earth referenced) supplies.
Each unit must be
permanently earthed
according to EN 50178.
For permanent earthing:
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.
Refer to Appendix C: “Certification".
