WARNING
EXERCISE EXTREME CARE WHEN HANDLING UPS CABINETS TO
AVOID EQUIPMENT DAMAGE OR INJURY TO PERSONNEL. REFER TO
SEPARATE INSTALLATION MANUAL FOR EQUIPMENT HANDLING
INFORMATION AND INSTALLATION PROCEDURES.
FOLLOW ALL BATTERY SAFETY PRECAUTIONS IN 4.0 -
MAINTENANCE WHEN INSTALLING, CHARGING, OR SERVICING
BATTERIES. IN ADDITION TO THE HAZARD OF ELECTRIC SHOCK,
GAS PRODUCED BY BATTERIES CAN BE EXPLOSIVE AND SULFURIC
ACID CAN CAUSE SEVERE BURNS.
IN CASE OF FIRE INVOLVING ELECTRICAL EQUIPMENT, USE ONLY
CARBON DIOXIDE FIRE EXTINGUISHERS, OR OTHERS APPROVED
FOR USE IN ELECTRICAL FIRE FIGHTING.
EXTREME CAUTION IS REQUIRED WHEN PERFORMING
MAINTENANCE.
BE CONSTANTLY AWARE THAT THE UPS SYSTEM CONTAINS HIGH
DC AS WELL AS AC VOLTAGES. WITH INPUT POWER OFF AND THE
BATTERY DISCONNECTED, HIGH VOLTAGE AT FILTER CAPACITORS
AND POWER CIRCUITS SHOULD BE DISCHARGED WITHIN 30
SECONDS. HOWEVER, IF A POWER CIRCUIT FAILURE HAS
OCCURRED, YOU SHOULD ASSUME THAT HIGH VOLTAGE MAY
STILL EXIST AFTER SHUTDOWN. CHECK WITH A VOLTMETER
BEFORE MAKING CONTACT.
AC VOLTAGE WILL REMAIN ON THE SYSTEM BYPASS (SBB) AND UPS
OUTPUT CIRCUIT BREAKERS, AND THE STATIC BYPASS SWITCH,
UNLESS ASSOCIATED EXTERNAL CIRCUIT BREAKERS ARE OPENED.
CHECK FOR VOLTAGE WITH BOTH AC AND DC VOLTMETERS PRIOR
TO MAKING CONTACT.
WHEN THE UPS SYSTEM IS UNDER POWER, BOTH THE OPERATOR
AND ANY TEST EQUIPMENT MUST BE ISOLATED FROM DIRECT
CONTACT WITH EARTH GROUND AND THE UPS CHASSIS FRAME BY
USING RUBBER MATS.
SOME COMPONENTS WITHIN THE CABINETS ARE NOT CONNECTED
TO CHASSIS GROUND. ANY CONTACT BETWEEN FLOATING
CIRCUITS AND THE CHASSIS IS A LETHAL SHOCK HAZARD.
EXERCISE CAUTION THAT THE TEST INSTRUMENT EXTERIOR DOES
NOT MAKE CONTACT EITHER PHYSICALLY OR ELECTRICALLY
WITH EARTH GROUND.
