•
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 equipment that appears to be damaged.
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
