SAFETYINSTRUCTIONS ANDADDITIONALNOTES
•Installation should only be performed by qualified professionals according to the laws and regulations applicable in each country.
•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 http://zennio.com/licenses.

⚠Important notes:
•To program this device through the KNX bus, the
auxiliary power supply must remain connected
(24 VDC).
•This device is designed for standard electric strikes
(normally-open circuit, i.e., the lock remains closed in the
absence of current). When using fail-safe electric strikes
(normally-closed circuit, i.e., the lock opens in the
absence of current), a 24 VDC normally-closed relay
between the fail-safe electric strike and the device must
be installed.
•Please, use this device only to control one electric strike.
Parallel or serial connection of two or more electric
strikes is not allowed.
•The cable length between the power supply, Securel v3
and the electric strike should be 30 meters maximum.
