Provide overload protection and disconnect as required. Actuators may also be powered by 24 VDC. Two built-in auxiliary switches (2x SPDT), for end position indication, interlock control, fan startup, etc. 45 Actuators may be powered in parallel. Power consumption must be observed. 48 Parallel wiring required for piggy-back applications. 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. 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.
