AC Power Electrical Safety Guidelines

Caution: For switches with AC power supplies, an external surge protective device (SPD) must be used at the AC power source.

The following electrical safety guidelines apply to AC-powered switches:

AC-powered switches are shipped with a three-wire electrical cord with a grounding-type plug that fits only a grounding-type power outlet. Do not circumvent this safety feature. Equipment grounding should comply with local and national electrical codes.
You must provide an external certified circuit breaker rated minimum 15 A in the building installation.
The power cord serves as the main disconnecting device. The socket outlet must be near the switch and be easily accessible.
When a switch is equipped with two AC power supplies, both power cords (one for each power supply) must be unplugged to completely disconnect power to the switch.
Note the following warnings printed on the label next to the power supplies:
“CAUTION: THIS UNIT HAS MORE THAN ONE POWER SUPPLY CORD. DISCONNECT ALL POWER SUPPLY CORDS BEFORE SERVICING TO AVOID ELECTRIC SHOCK.”

“ATTENTION: CET APPAREIL COMPORTE PLUS D'UN CORDON D'ALIMENTATION. AFIN DE PRÉVENIR LES CHOCS ÉLECTRIQUES, DÉBRANCHER TOUT CORDON D'ALIMENTATION AVANT DE FAIRE LE DÉPANNAGE.”
