Dimensions of ACS 501 Units
Installation Site Power
The ACS 501 is designed for use on a three-phase system. Four wires (three
phase plus a ground wire) are required for the input wiring. Input and output
conductors, and branch circuit protection must be sized to local codes.
At least three (3) separate conduits are required; one each for input power,
output power, and control wiring.
Conduit Size
Figure 3-3 shows a bottom view of R2 and R3 ACS 501 drives, and conduit
sizes to fit wire-entry holes.
