Fuse Removal and
Replacement
Bolt-on Fuse Removal/Installation
Tools required:
3/8 in. drive ratchet, 2 in. extension, 6 in. extension, 12 in.
extension, 1/2 in. socket, 3/8 in. drive torque wrench.
1. Remove the two lower mounting nuts, lock and flat washers from the
mounting studs.
2. Remove the upper two mounting nuts, lock and flat washers from the
mounting studs and remove the fuse from the fuse mounting studs.
3. Install the replacement fuse on the four mounting studs, hold the fuse in
place, and install the upper two flat washers, lock washers and nuts.
Torque nuts to 14.5 N•m (11 lb•ft).
4. Install the lower two flat washers, lock washers and nuts. Torque nuts to
14.5 N•m (11 lb•ft).
5. If interphase barriers were previously removed ensure they are properly
reinstalled.
ATTENTION:
Only personnel who have been trained and understand
the Bulletin 1500 product line are to work on this equipment. Suitable
safety equipment and procedures must be used always.
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.
ATTENTION:
The fuses may be hot for up to 1 hour after operating.
Verify the temperature before handling and use insulated hand
protection if needed. Failure to do so may result in burns.
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 fuse configuration will determine what length of extension
will be required to get at the mounting hardware. The fuse
configuration will also determine what size of interphase barriers
are installed, the lower barriers can be removed to provide better
access to the fuse mounting nuts.
