IMPORTANT SAFETY INSTRUCTIONS
Save These Instructions.
This manual contains important instructions that should be followed during installation and maintenance of your Series 600T UPS and batteries.
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.
