Motor Cable Length
Maximum motor cable length is 164 ft (50 m). Motor cable length is given to ensure performance of only the
SED2, not the suitability of the motor when connected to a SED2 at this distance. See Figure 8 for motor cable
installation notes.
Figure 8. Motor Cable Installation Notes.
Wiring Connections
See Figures 12 and 13 for all E-Bypass wiring.
1. Route shielded twisted pair (recommended wire type) cable, 24-gauge minimum control wiring in conduit
through knockout and into housing (Figures 9 through 11). Connect control wiring per job-specific drawings
and Figure 12.
NOTES:
• Terminate shield at control device.
• Control wiring is 12 to 26 AWG and tightening torque is 5 lb-in.
2. If applicable, route communications wiring (P1) in conduit through knockout and into housing (Figures 9
through 11). Continue to route communications wiring to VFD and terminate per SED2 VFD Startup,
Operation, and Maintenance Manual (125-3201).
NOTE: Communication wiring should be run with maximum separation possible from all other wiring.
3. Route motor wiring in conduit through knockout and into housing (Figures 9 through 11). Connect motor
wiring to motor overload and ground lug. See Tables 4 through 7 for wire sizes and tightening torques.
4. Route input power wiring in conduit through knockout and into housing (Figures 9 through 11). Connect input
power wiring to disconnect switch and ground lug or to circuit breaker and ground lug. See Tables 4 through 7
for wire sizes and tightening torques.
WARNING:
Use only permanently wired input power connections.
