PowerFlex 700L Technical Data

Publication 20L-TD001A 21

Best performance is achieved with three spaced ground conductors, but acceptable performance below 200 HP is provided

via a single ground conductor.

Cable Trays and Conduit

If cable trays or large conduits are to be used, refer to guidelines presented in the Wiring and Grounding Guidelines for

Pulse Width Modulated (PWM) AC Drives, publication DRIVES-IN001.

Power Ratings and Branch Circuit Protection

Frame 2 Drive

Most codes require that upstream branch circuit protection be provided to protect input power wiring.

The Frame 2 drive does not provide input power short circuit protection. The tables below provide drive ratings and

recommended AC line input fuse and circuit breaker information. Both types of short circuit protection are acceptable for

UL and IEC requirements. Sizes listed are the recommended sizes based on 40°C and the U.S. N.E.C.

Other country, state

or local codes may require different ratings.

Fusing

If fuses are chosen as the desired protection method, refer to the recommended types listed below. If available amp

ratings do not match the tables provided, the closest

fuse rating that exceeds the drive rating should be chosen.
