Power consumption must be observed. 48Parallel wiring required for piggy-back applications.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.Apply only AC line voltage or only UL-Class 2 voltage to the terminals of auxiliary switches. Mixed or combined operation of line voltage/safety extra low voltage is not allowed.
