Before cleaning the device, unplug it from the
socket outlet. Use a dry linen cloth to clean the
device. If the device is particularly dirty, you can
slightly dampen the cloth to clean it. Do not use
any detergents containing solvents for cleaning
purposes. Make sure that no moisture will ingress
into the housing.
If you use the device in a security application it
has to be operated in connection with an UPS
(uninterruptible power supply) in order to bridge
possible power failure according to EN 50130-4.
Do not connect multiple pluggable switches
into one another.
Devices with electronic power supply units (e.g.
TV or high voltage LED light sources) are no ohm-
ic loads. They can generate inrush currents with
more than 100 A. Switching such kind of loads
may lead to premature wear of the actuator.
The device may only be operated within residen-
tial buildings.
