CHAPTER 3
Maintaining and servicing the RTU
19
If you have verified that the battery needs to be replaced, follow
these steps to do so:
1. Open the lid by unscrewing the four screws in the corner of
the addIT RTU.
2. Gently remove the lid (the battery is fixed on the lid and is
connected to the electronics board by means of a connector).
3. Remove the battery’s plug from the PCB connector.
4. Remove the battery pack from the lid (it is taped to the lid)
and replace it with a new one (obtainable from Adcon).
5. Insert the battery plug into the PCB connector.
6. Mount the lid back, taking care that the rubber gasket sealing
the box is not out of place.
WARNING Be sure to mount the rubber gasket properly, so that
the unit’s IP65 environmental protection is not affected.
7. Screw the four screws back in, applying a moderate force.
