AC Power Electrical Safety Guidelines for EX4400
Switches
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
ts only a grounding-type power outlet. Do not circumvent this safety feature. Equipment grounding
must comply with local and naonal electrical codes.
• You must provide an external cered circuit breaker (2-pole circuit breaker on your device current
rang) rated minimum 13 A, 16 A, or 20 A in the building installaon or as per local electrical code.
• The power cord serves as the main disconnecng 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 connecon, you must ensure that all power
connecons 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).
