Maintenance 5-7
1512A-UM102B-EN-P – June 2013
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.
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.
NOTE: 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.
The fuses may be hot for up to one hour after oper-
ating. Verify the temperature before handling and
use insulated hand protection if needed. Failure to
do so may result in burns.
