•
Slide the conductors through the conduit.
•
Connect the conductors:
•
Connect the phase conductors of the motor cable to terminals T1/U, T2/V and T3/W. Connect the twisted shield of
the cable to the grounding terminal. (3a)
•
Connect the grounding conductor to the grounding terminal. Connect the phase conductors of the input power
cable as was done for the motor cabling. Use terminals L1, L2 and L3 if no disconnect option is present
optional disconnect is present, connect the input power cable conductors to the disconnect switch at terminals 2T1,
4T2 and 6T3. (3b)
