Wiring Diagrams
Actuators with appliance cables are numbered.
A
Provide overload protection and disconnect as required.
Actuators may also be powered by 24 VDC.
Actuators Hot wire must be connected to the control board common.
Only connect common to neg. (-) leg of control circuits. Terminal
models (-T) have no-feedback.
Actuators may be connected in parallel if not mechanically linked. Power
consumption and input impedance must be observed.
Actuators are provided with a numbered screw terminal strip instead of
16
a cable.
