Wiring for Multiple SY
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.

NOTES
•
Caution:
Power Supply Voltage.
• Isolation relays must be used in parallel connection of multiple actuators
using a common control signal input.
• "H" (L2) cannot be connected to terminal #3 and #4 simultaneously.
•
Required:
Terminal #7 needs to be field wired to enable heater circuit.
