It’s a vital component for understanding power consumption and ensuring efficient battery management within your RV or mobile setup. Proper functioning of this unit is paramount for reliable system operation and informed decision-making regarding power usage.
Current Shunt
The Current Shunt is a critical component responsible for accurately measuring the flow of current into and out of the battery system. It operates on the principle of sensing voltage drop across a low-resistance conductor, providing a precise indication of amperage. This data is then relayed to the Battery Monitor Unit for calculation of battery state of charge and overall system performance.
Correct installation and wiring of the current shunt are essential for accurate readings; improper connections can lead to significant errors in battery monitoring. The shunt must be placed in the negative battery cable, ensuring all current passes through it. Regular inspection of the shunt and its connections is recommended to maintain system reliability and ensure continued accurate measurements.

Remote Switch (RSW) Functionality
The Remote Switch (RSW) provides a convenient method for controlling accessories connected to the communication bus, offering enhanced power management capabilities. Importantly, battery charging remains unaffected by the operation of this switch. Any standard switch and appropriately sized wiring can be utilized for implementation, providing flexibility in installation and user preference;
Activation of the RSW effectively turns off all accessories linked to the communication bus, conserving energy when not in use. This feature is particularly useful for extended off-grid applications or when storing the RV. For specific cable accessories and compatibility details, refer to the comprehensive resources available on the BMPRO by Setec website, ensuring a seamless and optimized system integration.

Proper installation involves securely mounting the unit and correctly wiring the current shunt and optional Remote Switch Terminal (RSW) for optimal function.
Mounting the Battery Plus 35 11HA
Careful mounting ensures reliable operation and protects the Battery Plus 35 11HA from damage. Select a location that is dry, well-ventilated, and relatively free from vibration. Avoid areas near heat sources or direct sunlight. The unit should be mounted securely to a solid surface using appropriate fasteners – screws are generally recommended, ensuring they are of a suitable length to avoid penetrating internal components.

Consider accessibility for future maintenance or troubleshooting when choosing the mounting location. Ensure sufficient space around the unit for wiring connections. It’s crucial to avoid mounting the unit in a way that strains the wiring harness. Proper mounting contributes significantly to the longevity and accurate performance of the entire system, safeguarding your investment and providing peace of mind during your travels.
Wiring the Current Shunt
The current shunt is a critical component for accurate battery monitoring. It must be installed correctly within the negative battery cable, as close to the battery as possible, to measure current flow effectively. Ensure the battery is disconnected before commencing any wiring. The shunt connects in series with the negative terminal; the negative cable from the battery connects to one side of the shunt, and another cable runs from the other side of the shunt to the vehicle’s negative bus.
Use appropriately sized cable for the current carrying capacity. Secure connections are paramount – use crimped connectors and ensure they are firmly attached. Incorrect wiring or loose connections will lead to inaccurate readings and potentially damage the system. Double-check all connections before reconnecting the battery.
Connecting the Remote Switch Terminal (RSW)
The Remote Switch Terminal (RSW) allows for convenient control of accessories connected to the communication bus. Any standard switch and suitable wire gauge can be utilized for this connection. Importantly, battery charging functionality remains unaffected by the remote switch; it solely controls power to bus-connected accessories. This provides a simple method to isolate and conserve energy when needed;
Connect the switch to the designated RSW terminal on the Battery Plus 35. Refer to the BMPRO/Setec website for compatible cable accessories and detailed wiring diagrams. Proper wiring ensures reliable operation of the remote switch functionality, enhancing system usability and control.
