INSTALLATION NOTES
A
Actuators with appliance cables are numbered.
Provide overload protection and disconnect as required.
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.
Actuators may be connected in parallel if not mechanically linked. Power
consumption and input impedance must be observed.
Meets cULus requirements without the need of an electrical ground
connection.
