Wiring for Damper Actuators and Control Valves
On/Off, 24V, 120/230V

Observe class 1 and class 2 wiring restrictions.

Transformer sizing = SY actuator draw X 1.25 (safety margin)
(Ex. SY2-24 requires 3.0A x 1.25 = 3.75A,
3.75A X 24 VAC = 90VA Transformer).

Indicates an action or condition that may cause irreversible
damage to the actuator(s) or associated equipment.

Equipment damage!
Power consumption and input impedance must be observed.

CAUTION

Indicates a potentially hazardous situation which, if not avoided,
