1.

Cleaning the adhesive surface

The surface must be free of dirt and moisture, otherwise the module temperature sensor
is likely to fall off after sticking.

• Use the cleaning cloth to wipe the surface of the PV module at the spot where the
sensor is to be affixed. The spot must be located on the underside of the PV module.

2. Remove the masking paper from the pre-mounted double-sided adhesive tape on the module
temperature sensor.

3.

Damage to the PV module if you press the sensor on too hard

It is possible to damage the PV module by pressing the module temperature sensor on too hard.

• Observe the notes on mechanical strength in the PV module manual.

• Stick the module temperature sensor to the clean adhesive surface on the PV module,
pressing it on as firmly as the mechanical strength allows.

4. Lay the module temperature sensor cable to the
mounting location of the connecting terminal plate.

5. Connect one insulated conductor of the module
temperature sensor to Pin 5 and the other to Pin 6
of the connecting terminal plate. This can be done
in any order.
