and Maintenance of Magnum SB
Insulated Case Low Voltage Power
Circuit Breakers
WARNING
DO NOT ATTEMPT TO INSTALL OR PERFORM MAINTENANCE
ON EQUIPMENT WHILE IT IS ENERGIZED. DEATH OR SEVERE
PERSONAL INJURY CAN RESULT FROM CONTACT WITH
ENERGIZED EQUIPMENT. ALWAYS VERIFY THAT NO VOLTAGE
IS PRESENT BEFORE PROCEEDING. ALWAYS FOLLOW
SAFETY PROCEDURES. EATON IS NOT LIABLE FOR THE
MISAPPLICATION OR MISINSTALLATION OF ITS PRODUCTS.
WARNING
OBSERVE ALL RECOMMENDATIONS, NOTES, CAUTIONS, AND
WARNINGS RELATING TO THE SAFETY OF PERSONNEL AND
EQUIPMENT. OBSERVE AND COMPLY WITH ALL GENERAL
AND LOCAL HEALTH AND SAFETY LAWS, CODES, AND
PROCEDURES.
CAUTION
TESTING A CIRCUIT BREAKER WHILE IN-SERVICE AND
CARRYING LOAD CURRENT IS NOT RECOMMENDED FOR
POWER AND MEDIUM VOLTAGE CIRCUIT BREAKERS. TESTING
THAT RESULTS IN THE TRIPPING OF THE CIRCUIT BREAKER
SHOULD BE DONE ONLY WITH THE CIRCUIT BREAKER IN A
DEENERGIZED SYSTEM OR IN THE TEST OR DISCONNECTED
CELL POSITIONS OR WHILE IT IS ON A TEST BENCH.
PERFORMING TESTS WITHOUT THE EATON-APPROVED TEST
KIT MAY DAMAGE THE TRIP UNIT.
