Wiring Diagrams
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 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).
46
Actuators may be controlled in parallel. Current draw and input
impedance must be observed.
47
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.
