Three Phase
The operator is field configurable for usage at 208, 240, and 480 Vac. Factory default is 240 Vac. For three phase 575V operators, the operator is
configured at the factory for 575V ONLY.
For 208 Vac Operation
Ensure the motor harness is plugged in to the “208V / 240V” receptacle on the power board. Swap the orange and red
transformer wires (the red wire connects to the 240V position and the orange wire connects to the 208V position).
For 480 Vac Operation
Unplug the motor power harness from the“208V / 240V” receptacle on the power board and plug the harness into the
“480V” receptacle.
1. Make sure the AC power switch on the operator is OFF (the AC power switch will turn the incoming power ON or OFF).
2. Turn off the AC power from the main power source circuit breaker.
3. Run the AC power wires to the junction box on the operator.
4. Remove the junction box cover.
5. Connect the operator wires to line power via the white, black, and green wires in the junction box. Follow the table in the specification section for the
appropriate wire gauge for your application.
6. Replace the junction box cover. Ensure the wires are not pinched.
7. Turn on the AC power from the main power source circuit breaker.
8. Turn on the AC power switch.
NOTE:
To use a heater with the 480V configuration an additional step down transformer is required.
