Section 5: Inspection, Testing and
Maintenance
For complete instructions regarding inspection and testing of
Magnum DS switchgear and switchboards prior to start-up and oper-
ation, see Section 5 of IB01901001E. Read and follow all instructions
regarding safety practices described therein.
DANGER
ENERGIZING THE SWITCHGEAR FOR THE FIRST TIME IS POTENTIALLY
DANGEROUS. THEREFORE, ONLY QUALIFIED PERSONNEL SHOULD BE
PRESENT WHEN THE EQUIPMENT IS ENERGIZED. IF PROBLEMS CAUSED
BY DAMAGE OR POOR INSTALLATION PRACTICES HAVE NOT BEEN
DETECTED IN THE CHECKOUT PROCEDURE (PREVIOUSLY DESCRIBED),
DEATH, PERSONAL INJURY OR SERIOUS DAMAGE MAY RESULT WHEN
POWER IS APPLIED.
For instructions regarding periodic maintenance of switchgear/
switchboard devices, bus and connections, as well as replacement
parts, see Section 6 of IB01901001E. Read and follow all instructions
regarding safety practices described therein.
DANGER
WHEN ENERGIZED, A CIRCUIT BREAKER IS PART OF A HIGH POWER
SYSTEM. BEFORE ATTEMPTING ANY INSPECTION OR MAINTENANCE,
BE SURE THAT ALL PRIMARY AND CONTROL CIRCUITS HAVE BEEN
DE-ENERGIZED AND GROUNDED AS REQUIRED. ALSO MAKE CERTAIN
THAT PROPER STEPS HAVE BEEN TAKEN TO BE SURE THAT THEY WILL
REMAIN DE-ENERGIZED UNTIL ALL WORK IS COMPLETED. FAILURE TO DO
SO MAY RESULT IN DEATH, BODILY INJURY OR ELECTRICAL SHOCK.
