12. Connecting the storage system temperature sensor

Installing the storage system temperature sensor enables optimum charging to be carried out and extends the lead-
acid battery life.
This chapter explains the requirements and process for connecting the storage system temperature sensor to the
unit. Read carefully before starting the connection process.
INFO
Ingeteam recommends locating the sensor on a battery located in the central area of the storage system. It
should be placed approximately at the center, vertically, of the cell selected, and suitably fixed in accordance
with the installation specifications.
Use a 3-wire PT-100 temperature sensor.
12.1. Safety instructions for connecting the storage system
temperature sensor
CAUTION
Before you start to make the connections, make sure there is no voltage in the inverter. Verify that the AC
protection of the auxiliary genset and the DC protection of the storage system are open, as well as the PV array
and the consumption grid.
Do not switch on the power to the unit until you have successfully made the rest of the connections and the unit
is closed.
When carrying out the connections, respect the polarities marked on the electronic card.
