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 cha
fi
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
.
