3 INSTALLATION
3.1 Tools and equipment required
Installation of the Masterlink MICC involves only
eight wires and two 6 pole modular
communication cables (RJ12, cross wired). The
following sections describe a basic installation
such as you would find on an average boat, RV
or in a solar application.
First gather all the tools you need for the
installation of the Masterlink MICC.
We recommend as a minimum tool kit:
x A saw to make the panel cut-out
x A 10-mm drill to make holes for feeding
through the wiring between the panel, the
shunt and the batteries.
x A 14 mm spanner for shunt connections
x Wire stripper and crimper
x 2 mm and 5 mm flat blade screwdrivers.
A complete set of spanners, pliers and
wrenches may be helpful during the installation
of the Masterlink MICC.
3.2 Materials needed for installation
Make sure you have all the parts you need for
the job:
x A 500A/50mV shunt (supplied with the
Masterlink MICC)
x Cable(s) long enough to easily reach from
the batteries to the Masterlink MICC
(maximum length of the cables: 25 meters /
80ft.):
x Either: One cable 4x2x0,25 mm² shielded
twin twisted pair
x Or: One cable 2x0.25 mm² shielded
twisted pair and three normal 2-core
cables 2x0,25 mm²
x Two 6 pole modular communication cables
(RJ12, cross wired; see figure 1) to connect
the Masterlink MICC to the Mass Sinus
inverter and the Mass charger.
x Three inline fuse holders with 2 Amp fuses
(do not install the fuses before the
installation is completed).
x An as short as possible heavy-duty battery
cable to run from one shunt bolt to the main
battery. The size of this cable is usually
35-70 mm² but can vary depending on the
system. (Consult your Mastervolt dealer if
the wire size is unknown.) This cable is
commonly available from your Mastervolt
dealer or at marine and auto shops.
x Cable terminals and cord end terminals.
x If an external low battery alarm is required: a
normal cable 2x0.25 mm². The maximum
Mastervolt
