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.
