SAFETY INSTRUCTIONS AND ADDITIONAL NOTES
•
Installation should only be performed by qualified professionals according to the laws and regulations applicable in each coun try.
•
Do not connect the mains voltage nor any other external voltage to any point of the KNX bus; it would represent a risk for th e 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
