External temperature sensor inputs
Each external NTC 10 kΩ temperature sensor is
supplied with SMARTSHUNT for additional information
of battery status. With it we can calculate even more
precise capacity of battery that changes with
temperature. Besides that, lifetime of battery also
depends on temperature of environment, where
battery is stored. Sensor is supplied on 1 m long cable
that fits in two pin connectors labeled from T1 to T3.
On the other side of cable is ring lug terminal with
mounting whole diameter of 3.7 mm. When installing
system keep in mind that each sensor number refers
to same battery number. For example, sensor T1 is for
battery pack B1, T2 for B2 and T3 for B3.

Shunt
SMARTSHUNT is low side current sense device and it
must be placed between load and ground. Wire the
terminal labelled BATTERY - to battery ground and
LOAD - to ground from system load. Depends on
power needs use suitable cross sections of cables and
screw them with appropriate ring lugs, that are
compatible with shunt's screw thread size of M10.

NMEA2000 compatible M12 connector
M12 5-pin A-coded connector on top of unit is
compatible with NMEA2000 and has standard pinout.
When installing, follow the recommendations of
NMEA2000 network wiring. Always use free Tee
connector on existing network. Make sure that
connectors are tightened together properly to seal
metal contacts inside and prevent oxidation.
