2.5. Instructions for assembly and operational
start-up.
Never expose actuators to water (e.g. rain) or dust. This can damage the electronics.
You must not exceed a relative air humidity of 80%. Avoid condensation.
After the bus voltage has been applied, the device will enter an initialisation phase last-
ing a few seconds. During this phase no information can be received or sent via the
bus.
For KNX devices with safety functions (e.g. wind or rain blocks), it is important to set
up periodical monitoring of the safety objects. The optimal ratio is 1:3 (example: if the
weather station sends a value every 5 minutes, the actuator must be configured for a
monitoring period of 15 minutes).
