ELECTRICAL INSTALLATION
Wiring Guidelines
38
Wire Sizing
Size power wire to maintain a voltage drop less than 2% at VFD or motor terminals.
NOTE: Output reactors or filters are not required for 200/230V applications.
Frame A: Use only copper conductors rated for at least 75

C and 600 V. Use cable with a 90

C rating if
ambient environment is greater than 50

C.
Frame B and above: Use only copper conductors rated for at least 75

C and 600 V. Use cable with a 90

C
rating if ambient environment is greater than 40

C (30

C for models CXD-061A-2V, CXD-105A-2V, or
CXD-370A-4V).
460 and 575 V applications: Install a load (output) reactor to protect motor windings if distance from VFD
to a motor is in the range 45-100 ft (13.7-30.5 m). Install output dV/dt filter for a range 100-1000 ft (13.7-
304.8 m) or a sine wave filter for greater distances.
• For submersible pumps, install the output dV/dt filter for 800 ft (243.8 m).
Motor Cable Lengths for Submersible Pumping Applications
Refer to the Franklin Electric AIM Manual for wire gauge and distance information.
Suggested Maximum Motor Cable Lengths for Non-Submersible Applications
• Without output reactor: 13.7 m (45 ft)
• With output reactor: 30.5 m (100 ft)
• With dV/dt filter: 305 m (1000 ft)
