13. Electrical: Have a certified electrician run
appropriate power supply to motor, Fig.
21 & 22. Size wire for 20 amp circuit. See
Motor Operating Data Table.
CAUTION
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.

the motor.
NOTE: Assure cord used for connection
between the overhead switch and power
unit is of the type specified in:
UL201, Sections 10.1.1.3 & 10.1.1.4
(Example: SO, G, STO) Size for 25 amp
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.
