Installation
CAUTION:
Do not mount the ME-BMK in a closed battery
compartment, or in an area
where water
or any other liquid
can enter the module and cause shorting or corrosion—this
failure is not covered by the warranty.
CAUTION:
Before installing, ensure all AC power is
disconnected from the inverter, and all negative
and positive
battery cables are disconnected from the battery bank.
CAUTION:
Ensure all battery negative circuits are always
connected before connecting or disconnecting battery positive
.
This prevents any communication chips/lines from becoming
the DC return path to the battery—causing permanent damage
to all connected accessories.
Info:
Shunts require freely circulating air. For continuous
operation, do not use at more than 2/3 of its rated current. If
not possible, provide adequate forced ventilation to keep the
shunt operating at a temperature below 60°C (140°F).
Info:
Install the shunt as close to the battery bank as practical.
This helps prevent voltage drop and mistakenly placing a load
between the shunt and the battery.
2.2.1 DC Cable Connections
Once the shunt is mounted, make the following DC connections.
CAUTION:
The shunt must be installed in the negative DC line.
If installed on the positive side, damage may occur.
1. Using an appropriate sized cable, connect the inverter’s DC
negative terminal to the DC shunt’s load side (per Figure 2-1).
Info:
To monitor all of your system’s load currents/
DC loads—including the inverter—those loads must be
connected to the shunt’s load side.
2. Connect the battery side of the DC shunt to the battery’s negative
terminal. Secure both DC
cables to the shunt using the supplied
hardware (per
Figure 2-2). Torque from 16 to 20 ft-lbs.
3. Using an appropriate sized cable, connect the inverter’s DC
positive terminal to the load side of an appropriate DC disconnect/
overcurrent protection device (i.e., DC circuit breaker).
4. Open the DC circuit breaker (or remove the fuse) and connect
its other side to the positive terminal of the battery bank.
2.2 Installation
Procedure
Select a location that is dry and away from extreme temperatures
to mount the ME-BMK sense module and DC shunt. Ensure that you
can access the shunt’s screws and bolts, view the sense module’s
LED, and have access to the 4-port terminal block and the RJ14
communication port.
Note: Refer to Figure 5-1 for sense module and shunt dimensions.
