Locate the emergency power-off switch for the room in which you are working so that
if an electrical accident occurs, you can quickly turn off the power.
Do not work alone if potentially hazardous conditions exist anywhere in your workspace.
Never assume that power is disconnected from a circuit. Always check the circuit before
starting to work.
Carefully look for possible hazards in your work area, such as moist floors, ungrounded
power extension cords, and missing safety grounds.
Operate the services gateway within marked electrical ratings and product usage
instructions.
For the services gateway and peripheral equipment to function safely and correctly,
use the cables and connectors specified for the attached peripheral equipment, and
make certain they are in good condition.
In Case of Electrical Accident
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 rated minimum 20 A in the building
installation.
