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.
