Fuses
The G4106 is protected by two 0.5 A pico fuses on the
CMnet (+) and (-) terminals, and by one 3.0 A pico fuse on
the 24 VAC power terminal. See Figure 12 for their
location.
A blown fuse can indicate incorrect wiring , such as
reversed polarity, if the fuse blows during installation. In
most cases, a power surge to the board will be the cause of
the blown fuse.
An RMA is not necessary to replace these fuses. The fuses
are socketed and are field-replaceable. A kit is available
which contains 25 each of the four different types of fuses
that can be used to replace blown fuses (ALC part no.
FUSEPKG).

ALC production codes.
