13.1 Changing a fuse on the
PNI800 Panel Net Interface
The PNI800 has two fuses. Only one of the fuses is user
replaceable. See Table 29 for more information.
To replace the FU1 fuse, complete these steps:
1 Identify the blown FU1 fuse on the card visually or by
checking for continuity with a multimeter.
2 Insert a screwdriver under the centre of the fuse and
pull it out.
3 Check that the replacement fuse is of the correct
current rating.
4 Put the replacement fuse on top of the connector,
taking care that the current number is facing
upwards, and press it down firmly.
