INSTALLATION NOTES
Provide overload protection and disconnect as required.
Actuators may be connected in parallel. Power consumption and input
impedance must be observed.
Actuators may also be powered by 24 VDC.
Only connect common to negative (-) leg of control circuits.
A 500
Ω
resistor (ZG-R01) converts the 4 to 20 mA control signal to 2
to 10 VDC.
16
Actuators are provided with a numbered screw terminal strip instead of
a cable.
Meets cULus requirements without the need of an electrical ground
connection.
