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 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).
