IN A POCKET ATTACHED TO THE INSIDE OF LEFT DOOR OF EACH UPS.
FAILURE TO FOLLOW THOSE INSTRUCTIONS AND THE INSTRUCTION
LISTED ABOVE AND ELSEWHERE IN THIS MANUAL COULD RESULT IN AN
EXPLOSION, FIRE, EQUIPMENT FAILURE, OR ELECTROCUTION.

THIS EQUIPMENT CONTAINS CIRCUITS THAT ARE ENERGIZED WITH HIGH
VOLTAGES. ONLY TEST EQUIPMENT DESIGNED FOR TROUBLESHOOTING
HIGH VOLTAGES SHOULD BE USED, PARTICULARLY FOR OSCILLOSCOPES
AND PROBES.
ALWAYS CHECK WITH AN AC AND DC VOLTMETER TO ENSURE SAFETY
BEFORE INITIATING CONTACT OR USING TOOLS. EVEN WHEN THE POWER
IS OFF, DANGEROUSLY HIGH POTENTIAL VOLTAGES MAY EXIST AT
CAPACITOR BANKS. ALWAYS OBSERVE BATTERY PRECAUTIONS WHEN
OPERATING NEAR ANY BATTERIES.
FAILURE TO OBSERVE THESE PRECAUTIONS COULD RESULT IN DEATH,
INJURY OR DAMAGE TO EQUIPMENT.
Danger!
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 THE FILTER CAPACITORS AND POWER
CIRCUITS SHOULD DISCHARGE WITHIN 30 SECONDS. HOWEVER, POWER
CIRCUIT FAILURES CAN OCCUR, SO YOU SHOULD ALWAYS ASSUME THAT
HIGH VOLTAGE MIGHT STILL EXIST AFTER SHUTDOWN. VERIFY THAT
POWER IS OFF USING AC AND DC VOLTMETERS BEFORE MAKING
CONTACT.
