For more information go to www.p65warnings.ca.gov Piping The valves should be mounted in a weather-protected area in a location that is within the ambient limits of the actuator. Allow sufficient room for valve with actuator and for service. The preferred mounting position of the valve is with the valve stem vertical above the valve body, for maximum life. However, the assemblies can be mounted with valve stem vertical above the valve or up to 45° in relation to the horizontal pipe. The actuators should never be mounted underneath the valve, as condensation can build up and result in a failure of the actuators. Do not reverse flow direction.

Power consumption and input impedance must be observed. Actuators may also be powered by 24 VDC. A 500 Ω resistor (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. Contact closures A & B also can be triacs. A & B should both be closed for the triac source and open for triac sink. 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 with plenum cable do not have numbers; use color codes instead. 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.
