Motor Cable Length
Motor cable length is given to ensure performance of only the drive, not the suitability of the motor when
connected to a drive at this distance.
Maximum motor cable length is 164 ft (50 m).
See Figure 7 for installation notes.
Figure 6. Motor Cable Installation Notes.
Wiring Connections
NOTE: See Figures 11 through 13 for wiring schematic and terminations.
1. Do not mix control, motor, and input wiring in the same conduit. Run separate wire types with maximum
possible separation.
WARNING:
Failure to follow appropriate VFD wiring practice can result in sub-standard system operation and
may damage control components.
2. Route shielded, twisted pair, 24-gauge minimum cable for control wiring in separate conduit into enclosure
(Figures 6 through 8). Connect control wiring per job drawings and Figure 10.
NOTES:
• Terminate shield at control device.
• Control wiring is 12 to 26 AWG and tightening torque is 5 lb-in.
3. If applicable, route communications wiring (P1) in separate conduit into enclosure (Figures 8 through 10).
Continue to route communications wiring to VFD and terminate per SED2 VFD Startup, Operation, and
Maintenance Manual (125-3201).
CAUTION:
If applicable, route communications wiring with maximum separation from all other wiring. If wiring
through bypass enclosure, run communication wiring with maximum separation possible from all
other wiring.
