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 chafing; 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 2-5 during the following steps:
1. Unplug the Power Terminal Block from ME-SBC
TM
and ensure the openings
are unscrewed enough to allow the wires to be inserted.
2. Select and connect an appropriately sized red wire

#3 - COM NEG (-) should be sized for 30 amps and the same size. The battery
positive #1 - MAIN POS (+) and #2 - AUX POS (+) lines should be protected
with a 30 Amp fast blow fuse. Wire size should be appropriate for the application.
