resistance of the fastening.

2.3. Notes on mounting and commissioning

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

ge the electronic system.

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

lasting a few seconds. During this phase no information can be received or sent via

the bus.

Addressing of the device at the bus

The device is supplied with the bus address 15.15.255. You can program another ad-

dress into the ETS by overwriting the 15.15.255 address or by teaching via the pro-

gramming key on the circuit board inside the housing.
