Power Wiring All actuators include a barrier that separates the power wiring compartment from the low
voltage wiring compartment. Refer to Table-9 for allowable circuit class for the two wiring
compartments.
Table-9 Actuator Circuit Class.
Refer to Table-10 for selection of proper gage wire for the length of wire run (one run has
two wires).
Table-10 Power Wire Selection.
When multiple 24 Vac actuators are powered from the same transformer, the actuators must
be in phase. Connect the same transformer lead to the “G” terminal on all actuators and
same transformer lead to the “H” terminal on all actuators.
