AC Power Electrical Safety Guidelines

Supported Platforms

Make sure that grounding surfaces are cleaned and brought to a bright finish before

grounding connections are made.

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 device within marked electrical ratings and product usage instructions.

To ensure that the device and peripheral equipment function safely and correctly, use

the cables and connectors specified for the attached peripheral equipment, and make

certain they are in good condition.

You can remove and replace many device components without powering off or

disconnecting power to the device, as detailed elsewhere in the hardware documentation

for this device. Never install an equipment that it appears to be damaged.

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.
