IMPORTANT: 115/230 Volt single phase models are
shipped from factory with motor wired for 230 volts. If
power supply is 115 volts, remove motor canopy and
reconnect motor as shown in Figure 8. Do not try to run
motor as received on 115 volt current.
8. Motor has automatic internal thermal overload
protection. If motor has stopped for unknown
reasons, thermal overload may restart it
unexpectedly, which could cause injury or property
damage. Disconnect power before servicing motor.
9. If this procedure or the wiring diagrams are
confusing, consult a licensed electrician.
Connection diagram for dual voltage, single-phase
motors. Your dual-voltage motor's terminal board
(under the motor end cover) will match one of the
diagrams below. Follow that diagram if necesary to
convert motor to 115 Volt power.
Connect power supply wires to L 1 and L 2 . For 3-phase
motors, or if motor does not match these pictures,
follow the connection diagram on the motor nameplate.
The motor is set for 230 volts when shipped.
To change the motor to use 115 volts:
1. Turn off power
2. Remove the back motor cover.
