INSTALLATION
3.1
M
ONITOR
Install the battery monitor in a protected, dry and well-visible place so that it can be read at any time. The
mounting cut-out is 88 x 88 mm and the required minimum depth is 40 mm. On the back, there is a 3-poles
terminal for powering the monitor and the communication line to the shunts (single wire). A potential-free
contact (relay output) is available on a 2-poles terminal. The software can be updated with a micro-SD card.
If the power supply of the display is switched-off,
the history is lost. However, the counting of
Ampere hour (Ah) is still performed by the shunt.
3.2
S
HUNT
Install the shunt as close to the battery as possible in a protected, dry place.
The shunt must be connected to
the Minus path of the battery (B-).
On the shunt, following connections are available at the 6 poles connector:

Detailed function
+1
Battery voltage measuring
lead (+1) and power supply for
shunt
This cable is essential to ensure a complete recording of the
battery capacity. It should only be disconnected in winter
storage.
+2
Additional battery voltage
measuring lead (+2)
Optional connection to measure the voltage of an additional
battery (starter battery for instance). This is displayed as
battery n°2 on the monitor.
-T
Minus temperature sensor
(black wire)
Optional temperature sensor for sensing the battery
temperature (two optional versions available 2.8m or 5m,
reference STP-NEW-2.8 or STP-NEW-5.0). The temperature
sensor should be fixed on the outside of the housing of the
battery. The temperature sensor has no active influence on the
capacity calculation or charge but is for information only.
+T
Plus temperature sensor
(blue wire)
LIN
LIN bus communication with
display (two poles available)
The monitor communicates with the shunts via this line.
