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.
At the shunt following connections are available at the 6 poles connector:
Pin No Name

The shunt must be connected to
the Minus path of the battery (B-).
Detailed function
This cable is essential to ensure a complete recording of the
battery capacity. It should only be disconnected in winter
storage Due to the very low power consumption in sleep
mode, the shunt does not put any additional load on the
battery.
Optional connection to measure the voltage of an additional
battery (starter battery for instance). This is displayed as a
battery n°2 on the monitor.
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.
The monitor communicates with the shunts via this line.
