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 Ω resistor (ZG-R01) converts the 4 to 20 mA control signal to 2 to 10 VDC.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.
