2.4. Notes on mounting and commissioning

Do not open the device if water (rain) might ingress: even some drops might damage

the electronic system.

After the bus voltage has been applied, the device will enter an initialisation phase las-

ting 5 seconds. During this phase no information can be received via the bus.

The sensor must regularly be checked for dirt twice a year and cleaned if necessary. In

case of severe dirt, the sensor may not work properly anymore.

As a precaution, the device should always be separated from

bus current for maintenance works.
