SAFETY INSTRUCTIONS AND ADDITIONAL NOTES
•
Installation should only be performed by qualified professionals according to the laws and regulations applicable in each cou ntry.
•
Do not connect the mains voltage nor any other external voltage to any point of the KNX bus; it would represent a risk for the entire
KNX system. The facility must have enough insulation between the mains (or auxiliary) voltage and the KNX bus or the wires of other
accessories, in case of being installed.
•
Once the device is installed (in the panel or box), it must not be accessible from outside.
•
Keep the device away from water (condensation over the device included) and do not cover it with clothes, paper or any other material
while in use.
•
The WEEE logo means that this device contains electronic parts and it must be properly disposed of by following the instructions at
https://www.zennio.com/en/legal/weee-regulation.
•
This device contains software subject to specific licences. For details, please refer to https://zennio.com/licenses.
