Installation
CAUTION: DO NOT plug in the 8-port terminal block.
After
all the wiring to the controller is complete and all the settings
have been con
fi
gured, a power-up test will be performed
(Section 3.3.1).
DO NOT
plug in the 8-port terminal block
until the power-up test has been successful.
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 3.3 mm
2
).
2.5.1 Power Connections (Terminals 3 and 4)
1. Connect a wire (black) from the monitored battery bank’s
negative terminal to Terminal 4 on the 8-port terminal block.
2. Connect a wire (red) with a 5-amp in-line fuse from the
monitored battery bank’s positive terminal to Terminal 3 on the
8-port terminal block.
2.5.2 Generator Run Sense Connection (Terminal 2 and 4)
Terminal 2 on the 8-port terminal block is used as a generator
run sense (i.e., switched B+ or a positive battery signal from the
hour meter or gen running light). This run sense voltage is used to
determine that the generator is operating and to prevent another
starter crank while the generator is running.
Info:
The run sense signal from the generator to Terminal 2
(positive) and Terminal 4 (negative) must be between 10-40
VDC and only while the generator is running.
3. Connect a wire (preferably not black or red) from the generator’s
run sense output to Terminal 2 on the 8-port terminal block.
4. Connect the negative terminal of the monitored battery bank to
Terminal 4 (power negative) on the 8-port terminal block. Ensure
the negative terminal on the generator battery is referenced/
connected to the negative terminal on the monitored battery.
Info:
The negative side of the run sense signal from the
generator must be in common with the negative side of the
monitored battery bank. This ensures that the positive battery
voltage (to Terminal 3) and the positive run sense voltage (to
Terminal 2) have a common negative reference (to Terminal
4) and are correctly measured by the ME-AGS-S.
