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 chafi 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.
