Wiring Diagrams

INSTALLATION NOTES

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

to 10 VDC.

Control signal may be pulsed from either the Hot (Source) or Common

(Sink) 24 VAC line.

For triac sink the Common connection from the actuator must be

connected to the Hot connection of the controller. Position feedback

cannot be used with a triac sink controller; the actuator internal

common reference is not compatible.

IN4004 or IN4007 diode. (IN4007 supplied, Belimo part number

40155).

Actuators are provided with a numbered screw terminal strip instead of

a cable.

Actuators may be controlled in parallel. Current draw and input

impedance must be observed.

Master-Slave wiring required for piggy-back applications. Feedback

from Master to conrol input(s) of Slave(s).

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.
