7 MAINTENANCE AND INSPECTION INSIDE THE ELECTRICAL CABINET
Even when the main power switch (non - fused circuit breaker) on the electrical
cabinet is turned OFF, parts of the cabinet may still have potential and may
give an electric shock if accidentally touched. Before attempting maintenance
and inspection inside the electrical cabinet, be sure to turn OFF the power at
the circuit breaker for the entire plant. It is necessary to conduct maintenance
with the power being supplied, confirm the state of power supply by checking
the electric wiring diagram and exercise extreme caution.
