AC Power Electrical Safety Guidelines for EX Series Switches
CAUTION: For switches 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 switches:
•
Note the following warnings printed on the chassis:
“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 switches 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 switch. The socket
outlet must be near the switch and be easily accessible.
•
For EX Series switches that have more than one power supply connection, you must
ensure that all power connections are fully disconnected so that power to the switch
is completely removed to avoid electric shock. To disconnect power, unplug all power
cords (one for each power supply).
