Hazard information
For secure operation, the device has to be installed
in a power distribution panel according to VDE
0603, DIN 43871 (low-voltage sub-distribution
board), DIN 18015-x. The installation must be car-
ried out on a mounting rail (DIN rail) according to EN
60715. Installation and wiring have to be performed
according to VDE 0100 (VDE 0100-410, VDE 0100-
510 etc.). Please consider the technical connection
requirements (TAB) of your energy supplier.
Before installation and connection of the device,
mains voltage must be disconnected and live
parts in the surrounding must be covered.
The device has not been designed to support
safety disconnection.
Devices with electronic power supply units (e.g.
high voltage LED light sources) are no ohmic
loads. They can generate inrush currents with
more than 100 A. Switching such kind of loads
may lead to premature wear of the actuator. In
such cases, we recommend to use switch-on
current limiters at the switching outputs.
The device may only be operated within domes-
tic environment, in business and trade areas as
well as in small enterprises.
