2.2.2 ME-BMK Sense Module connections
The sense module should now be mounted, refer to figure 2-3 for reference during
the following steps:
1. Run the communications cable between the ME-BMK Sense Module and the in-
verter/charger. This cable is a 2-wire, twisted-pair, telephony standard with RJ11
connectors on each end. A standard telephone cable may be substituted if the
provided remote cable is not able to be used or needs to be longer.
2. Connect the Communications cable into the RJ11 “Comms port” beside the
green label (also referred to as the “Network” port) on the MagnaSine inverter/
charger (see figure 2-1).
3. Unplug the 4-port terminal block from ME-BMK Sense Mode and ensure the
openings are unscrewed enough to allow the wires to be inserted.
4. Using the supplied five foot twisted-pair wire: 1) connect the blue wire from the
#1 terminal on the 4-port terminal block to the small screw on the battery side of
the shunt (negative shunt sense connection); 2) connect the orange wire from the
#2 terminal on the 4-port terminal block to the small screw on the load side of the
shunt (positive shunt sense connection).
Info: Ensure these blue and orange wires stay twisted together up to the
shunt to maintain accuracy.
5. Connect a wire (black) from terminal #3 on the 4-port terminal block to the
negative terminal of the battery and connect a wire (red) with a 2-amp, in-line
fuse from terminal #4 on the 4-port terminal block to the positive terminal of the
battery.
Caution: To prevent damage, the black and red power wires must not be
connected to the input sense terminals (terminals #1 and #2).
6. When all the connections are made and checked, plug the 4-port terminal block
into the sense module and then close the DC circuit breaker (or DC disconnect) to
supply power to the inverter and sense module.
7. Immediately after applying DC power, the LED on the sense module should
come on as the unit goes through a power-up self-test. After the initial self-test
completes, the LED should be on green. If so, your battery monitor system is now
ready for set-up; if not, please refer to the troubleshooting section.
