Spares 6-9
Spares
We recommend that you have one spare module or Power Supply
Unit for every ten in use. In the unlikely event that you should
have problems with the LinkBuilder MSH, you should swap the
faulty item with a spare. This allows you to continue operation
and may also help in singling out a fault, if the replacement solves
the problem.
It is advisable to hold spare replaceable components, such as
fuses and Transceiver Modules, even though they are unlikely to
fail. The bridge module has one replaceable fuse, see Figure 6-1
.
Fuse................................ 12V 2A anti-surge (20mm cartridge)
Only fuses of the same manufacturer, type and rating should be
used with the module.
