Wiring
Proportional, 24V, 120/230V
W547-2
Actuators: SY4...5-24MFT SY4...12-120MFT SY4...12-230MFT
Each actuator should be powered by a single, isolated
control transformer.
• Power supply Com/Neutral and Control Signal "–" wiring to a common is
prohibited.
Actuator: SY2…5-24MFT SY2...12-120MFT SY2...12-230MFT
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.
