Wiring Connections
NOTE: SQM5… actuators require a single source, single phase power supply.
Wiring connections vary depending on which AGA56…. circuit board is installed.
AGA56.1… circuit boards.
See Figures 7 and 8.
Manual Operation
1. Set the AUTO/MAN switch in the MAN position.
2. Connect ground to the screw located below the shaft release button.
3. Connect neutral to the double terminal block, located on the left side of the gray
switch housing.
4. Only terminal "L" must be to enable manual operation. The actuator can now be
driven to the maximum position (switch cam I) or the fully closed "economy
position" (switch cam II) by using the toggle switch located to the left of the
AUTO/MAN switch.
Automatic Operation
1. Set the AUTO/MAN switch in the AUTO position.
2. Connect ground to the screw located below the shaft release button.
3. Connect neutral to the double terminal block located on the left side of the gray
switch housing.
4. Connect line voltage to terminal A to drive the actuator in the opening direction.
5. Connect line voltage to terminal Z to drive the actuator in the closing direction.
CAUTION:
Do not power terminals A and Z simultaneously. Actuator damage will occur.
