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 Ωresistor (ZG-R01) converts the 4 to 20 mA control signal to 2

to 10 VDC.

Actuators are provided with a numbered screw terminal strip instead of

a cable.

Meets cULus requirements without the need of an electrical ground

connection.

!WARNING! LIVE ELECTRICAL COMPONENTS!

During installation, testing, servicing and troubleshooting of this

product, it may be necessary to work with live electrical components.

Have a qualified licensed electrician or other individual who has been

properly trained in handling live electrical components perform these

tasks. Failure to follow all electrical safety precautions when exposed to

live electrical components could result in death or serious injury.
