Power Wiring
Note:
For specified EMC emission and immunity performance, install to EMC Installation Instructions. Refer to Chapter
10: “Certification for the Drive” - for more information
Terminal tightening torque for Frame 3 power connections is 20 lb.in (2.26Nm).
Protect the incoming mains supply using the specified fuse, or RCD circuit breaker Type B.
IMPORTANT:
We do not recommend the use of circuit breakers (e.g. RCD, ELCB, GFCI), however, where their use is mandatory, they
must:
•
Operate correctly with dc and ac protective earth currents (i.e. type B RCDs as in Amendment 2 of IEC755).
•
Have adjustable trip amplitude and time characteristics to prevent nuisance tripping on switch-on.
