Connecting the AGS-N to a Generator
With the AGS already mounted, ensure the 8-port terminal block is
removed before proceeding with wiring the generator. Use the info
in this section to wire the AGS’s terminal block to the generator.
CAUTION: DO NOT plug in the 8-port terminal block until all
the wiring to the AGS controller is complete and you are ready
to perform the functional operation tests (Section 4.0).
CAUTION: You must use a fuse rated at
5 amps to protect all
power circuits connected to the AGS (do not fuse the negative
connection on Terminal #4). Ensure the fuse is correctly rated
for the wire size used. Refer to national/local codes for rating
and type. Normally, a minimum #16 AWG (1.31 mm
2
) wire
is required in order to use a 5-amp fuse.
Info: The green 8-port terminal block accepts CU/AL
conductors from #30 to #12 AWG (0.05 to 3.31 mm
2
).

Connections
When connecting devices together (via a network communications
cable), the return path (i.e., battery negative) of each battery
powered device must be at the same potential (i.e., electrically
common with each other—see Figure 2-9). This prevents a high-
impedance path developing between the connected devices, which
can cause the network cable to become the DC return path to the
battery—possibly resulting in permanent damage to all connected
devices on the network. This also requires that the battery negative
connection of each device be always connected before connecting/
disconnecting any battery positive.
