AC Power Electrical Safety Guidelines
CAUTION: For devices 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 devices:
•
Note the following warnings printed on the device:
“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.”
•
AC-powered devices 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 must
comply with local and national electrical codes.
•
You must provide an external certified circuit breaker (2-pole circuit breaker or 4-pole circuit breaker
based on your device) rated minimum 20 A in the building installation.
•
The power cord serves as the main disconnecting device for the AC-powered device. The socket outlet
must be near the AC-powered device and be easily accessible.
•
For devices that have more than one power supply connection, you must ensure that all power
connections are fully disconnected so that power to the device is completely removed to prevent electric
shock. To disconnect power, unplug all power cords (one for each power supply).
