WHEN SERVICING BATTERIES. THE HAZARD OF ELECTRIC SHOCK IS PRESENT
EVEN WHEN THE UPS IS OFF. MAINTAIN BATTERIES BELOW MAXIMUM
RECOMMENDED TEMPERATURE TO AVOID RELEASING SULFURIC ACID VAPORS.
IN CASE OF FIRE INVOLVING ELECTRICAL EQUIPMENT, ONLY CARBON DIOXIDE
FIRE EKTINGUISHERS, OR THOSE APPROVED FOR USE IN ELECTRICAL FIRE
FIGHTING, SHOULD BE USED.
EKTREMR CAUTION IS REQUIRED WHEN PERFORMING MAINTENANCE. LETHAL

INPUT/OUTPUT TERMINALS BATTERY CABINET, AND THE INPUT TRANSFORMER.
ALL INPUT POWER MUST BE REMOVED TO ACHIEVE COMPLETE ISOLATION.
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 AC AND DC VOLTMETERS BEFORE MAKING
CONTACT.
WHEN USING TEST EQUIPMENT WHILE 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
