Installation
2.4.2 ME-SBC
TM
Wiring Connections - Solenoid Drive
CAUTION:
Before connecting any wires, turn off any battery charger
and loads that are connected to the
battery banks that the ME-SBC
TM
will be combining.
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.
The ME-SBC
TM
should now be mounted, if not please refer to
section 2.2
.
During installation please refer to
Figures 2-6
during the following steps:
1. Unplug the
Power Terminal Block
from ME-SBC
TM
and ensure the open-
ings are unscrewed enough to allow the wires to be inserted.
2. Select and connect an appropriately sized red wire
1
from terminal
#1 -
MAIN POS (+)
on the
Power Terminal Block
to the positive terminal of
the
Main Battery
.
3. Select and connect an appropriately sized red with white stripe wire
1
from
terminal
#2 - AUX POS (+)
on the
Power Terminal Block
to the positive
terminal of the
Auxiliary Battery
.
4. Select and connect an appropriately sized black wire
1
from terminal
#3
- COM NEG (-)
on the
Power Terminal Block
to the negative busbar or
vehicle chassis.
Info:
The negative busbar must connect the negative terminals on
the
Main and Auxiliary Batteries
together.
5. Use an appropriately sized wire
2
to connect each terminal of the solenoid
to the appropriate battery terminal. Please refer to
Figure 2-4
for more
information
6. Connect one side of the solenoid coil to a positive post on the
Main or Aux-
iliary Battery
or one of the main terminal on the solenoid. Use the appropriate
fuse to protect the wire (2 Amp fast blow maximum). For more information,
please consult the solenoid manufacturers installation instructions.
7. Connect the other side of the solenoid coil to
# 4 - SOLENOID (-)
on the
Accessories Terminal Block
.
8. When all the connections are made and checked, plug the
Power Terminal
Block
into the ME-SBC
TM
to supply DC power.
9. Immediately after applying DC power, the LED’s on the ME-SBC
TM
should
come on as the unit goes through a power-up self-test. After the initial self-
test completes, the
Status LED
should be Illuminated. If not, please refer to
the troubleshooting section.
note 1 :
The wires connected to
#1 - MAIN POS (+)
,
#2 - AUX POS (+)
and #3 - COM NEG (-)
should be sized for 30 amp. The battery positive
lines should be protected with a 30 Amp fast blow fuse. Wire size should be
appropriate for the application.
note 2 :
The size of this wire will likely be determined by considering the
3% voltage drop requirements of the charging circuit. Always consult the
solenoid manufacturers installation documentation.
