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,
may result in minor or moderate injury. It may also be used to
alert against unsafe practices.
Warnings and Cautions appear at appropriate sections throughout
this manual. Read these carefully.
