Replace a fuse
WARNING
Ensure that you replace a fuse with a new fuse of the correct rating. If you do not,
the iL system will not be adequately protected and you can damage the iL system
or cause injury to people.
Note:
You can only change the fuses in fuse holders F7, F8 and F9. A BOC Edwards service engineer
must change other fuses in the Electrics and Pump Control Module (see Figure 1-4).
You can only change the low voltage fuses F7 to F9 for the d.c. electrical supply, the iL Interface
Module and the emergency stop circuit. If any of the internal fuses have failed, you must contact
your supplier or BOC Edwards for advice. Only change a fuse if you have identified and
rectified the cause of the failure.
To change a fuse, refer to Figure 1-4 and use the following procedure. If the fuse immediately
fails when you replace it, there may be an electrical fault: contact your supplier or BOC Edwards
for advice.
