ATTENTION: Servicing energized industrial control equipment can be
hazardous. Severe injury or death can result from electrical shock, burn, or
unintended actuation of control equipment. Hazardous voltages may exist in
the cabinet even with the circuit breaker in the off position. Recommended
practice is to disconnect or lock out control equipment from power sources, and
confirm discharge of stored energy in capacitors. If it is necessary to work in the
vicinity of energized equipment, the safety related work practices of NFPA 70E,
Electrical Safety requirements for Employee Work places, must be followed.
ATTENTION: To prevent electrical shock, ensure the main power has been
disconnected and equipment has been tagged and locked out. Verify that all
circuits are voltage free using a hot stick or appropriate voltage-measuring
device. Failure to do so may result in injury or death.
TIP
The main power fuse has a pop up indicator pin located at one end of the fuse.
When a fuse has opened, the indicator will be in its extended position. The fuse
should be oriented in the fuse clip assembly so that the indicator is at the top.
