Connecting the Cable
To connect the Echo Charger cable:
1. Route the cable from the engine battery to the Echo Charger port on the
MS2000.
2. Connect the cable to the fuse on the POSITIVE (+) terminal of the engine
battery.
3. Plug the Echo Charger connector into the port on the MS2000.
4. If it is not already connected, connect the engine battery negative terminal to
the engine negative terminal/bus.
This cable must be sized for all the loads on the engine battery (including start
current), not just the Echo Charger.
Step 6: Connecting the Battery Temperature Sensor (BTS)
Installing a battery temperature sensor (BTS) extends the life of the house battery
bank by preventing overcharging in warm temperatures and undercharging in cold
temperatures. With a BTS monitoring the battery temperature, the voltage
delivered to the house battery bank is adjusted according to the battery’s actual
temperature.
A 25-foot (7.6 m) cable is supplied with the BTS, as shown in Figure 13.
WARNING: Energy hazard
Connect and disconnect DC wiring only after opening the disconnect switches or breakers
at all AC and DC sources.
