2.4.3 ME-SBC
TM
Wiring - Remote Volt Sense
The Remote Volt Sense Wire, or the wire connected to #6 - SENSE (+), can
be used to better sense when the batteries are being charged. As the ME-SBC TM
combines the Main and Auxiliary Batteries, the current path distributes
voltage drops throughout the circuit that may cause the ME-SBC TM to cycle
unneccessarily. The Remote Volt Sense Wire, if utilitzed, tells the ME-SBC TM
what the actual voltage is by bypassing the current path and therefore the
voltage drops. The Remote Volt Sense Wire can be connected at the battery
or at the charging source (i.e. Alternator, Solar, Wind, etc).
CAUTION: Before connecting any wires, turn off any connected
battery charger and ensure all negative and positive battery cables
are disconnected from the battery bank.
Info: If installing in a boat, RV or truck, ensure the conductors
passing through walls, bulkheads or other structural members are
protected to minimize insulation damage such as chafi ng; which can
be caused by vibration or constant rubbing.
1. Install and connect the ME-SBC TM as indicated in Section 2.2.2 or Sec-
tion 2.2.3
2. Remote Volt Sense Wire: Install a minimum of an 18 AWG wire between
the Main Battery positive and the #6 - SENSE (+) on the accesories ter-
minal on the ME-SBC TM . The Remote Volt Sense Wire should be fused at
0.25 Amps with a fast blow fuse.
Info: Connect the highest current cable directly to the battery ter-
minal, and in descending order in terms of ampacity, connect the
rest of the cables. The Remote Volt Sense Wire should be the last
connection on the battery. For a detail of this information, please see
the Main Battery positive post in Figure 2-7.
