SECTION 5 – MAINTENANCE
5.1 SAFETY PRECAUTIONS
Danger!
READ AND UNDERSTAND THIS SECTION THOROUGHLY BEFORE
PERFORMING ANY MAINTENANCE WORK ON OR AROUND THE UPS. READ
THE BATTERY MANUFACTURER’S MANUAL AND MATERIAL SAFETY DATA
SHEETS BEFORE WORKING ON OR NEAR THE BATTERIES.
ONLY NORMAL SAFETY PRECAUTIONS ARE REQUIRED WHEN THE UPS IS
OPERATING WITH ALL CABINET DOORS CLOSED. HOWEVER, THE UPS
AND BATTERY CABINETS MUST BE KEPT FREE OF STANDING PUDDLES OF
WATER, EXCESS MOISTURE, OR DEBRIS. DEBRIS CAN CONSIST OF
EXCESSIVE DUST IN AND AROUND THE UNIT, AS THE COOLING FANS IN
THE UPS WILL PULL THIS DUST INTO THE UNIT.
Danger!
ONLY FACTORY TRAINED OR AUTHORIZED PERSONNEL SHOULD ATTEMPT
TO INSTALL OR REPAIR THE UPS OR ITS BATTERY SYSTEM. IMPROPER
INSTALLATION HAS PROVEN TO BE THE SINGLE MOST SIGNIFICANT
CAUSE OF START-UP PROBLEMS. SERVICE PERSONNEL SHOULD WEAR
INSULATING SHOES FOR ISOLATION FROM DIRECT CONTACT WITH THE
FLOOR (EARTH GROUND), AND SHOULD MAKE USE OF RUBBER MATS
WHEN PERFORMING MAINTENANCE ON ANY PORTION OF THE UNIT WHILE
IT IS UNDER POWER. HIGH AC AND DC ELECTRICAL VOLTAGES ARE
PRESENT THROUGHOUT THE UNIT(S) AND INCORRECT INSTALLATION OR
SERVICING COULD RESULT IN ELECTROCUTION, FIRE, EXPLOSION, OR
EQUIPMENT FAILURE.
Danger!
SPECIAL SAFETY PRECAUTIONS AND LOCKOUT TAGOUT PROCEDURES
ARE REQUIRED FOR ALL OPERATIONS INVOLVING THE HANDLING,
INSTALLATION, OR MAINTENANCE OF THE UPS SYSTEM AND ANY
ASSOCIATED BATTERY CABINETS. FAILURE TO FOLLOW SAFETY
PROCEDURES COULD RESULT IN DEATH, INJURY OR DAMAGE TO
EQUIPMENT.
