Intellitec Battery Disconnect Panel, BD0, 01-00066-004
Warning: The Battery Disconnect system connects directly to the vehicle's positive battery
terminal. Inadvertent shorts across the battery or to ground, may cause severe damage and
injury. Use extreme caution when working with these wires. Always wear safety glasses when
working with the battery connections.
Battery Disconnect provides a simple and safe means of remotely disconnecting
batteries of an RV or boat. With a touch of a remote switch, the batteries will be com-
pletely disconnected, preventing unwanted drain when the RV / boat are put into
storage.
The heart of the system is a unique latching relay developed specifically for this pur-
pose. While this relay is capable of carrying heavy currents, it requires NO power to
stay open or closed. It only draws power during activation. The relay is sealed against
the environments and is designed to withstand the shock and vibration experienced in
the most severe RV or boat applications.
