appropriate power supply to motor, Fig.
21 & 22. Size wire for 20 amp circuit. See
Motor Operating Data Table.
Never operate the motor on line
voltage less than 208V. Motor damage may
occur.
IMPORTANT: Use separate circuit for each
power unit. Protect each circuit with time
delay fuse or circuit breaker. For single phase
208-230V, use 20 amp fuse. Three phase 208-
240V, use 20 amp fuse. For three phase 400V
(*E Model) and above, use 10 amp fuse. For
three phase 380V (*S Model) use 16 amp fuse.
For wiring see Fig. 21, Fig. 22, and Fig.22b. All
wiring must comply with NEC and all local
electrical codes.

circuit. See UL 201, Section 15 for proper
wiring requirements for this connection.
*Notes: E or S Model?
To find out if you have a E or S model Power Unit look at the 4th
letter from the end of your lift model number.
EXAMPLE: SPOA10E585 would be a E Model.
Model number can be found on a tag on the side of the lift.
