5.1 Installation
The switch actuator and meter is installed optionally in a flush-type
box or in a surface box.
Installation must only be performed in industrially available switch-
boxes (mounting boxes) according to DIN 49073-1 or surface box
-
es according to DIN 60670-1 (e. g. Abox 025 or Abox 040).
Devices with electronic power supply units (e. g. TV sets or high
voltage LED lamps) do not represent ohmic loads. They can gen
-
erate inrush currents of up to 100 A. The switching of such consum-
ers leads to a premature wear of the actuator. In such cases, the
use of inrush current limiters at the switching outputs is recom-
mended.
The circuit the device and the load are connected to must be pro-
tected with a circuit breaker according to EN 60898-1 (triggering
characteristic B or C, max. 16 A nominal current, min. 6 kA breaking
capacity, energy limiting class 3). Installation guidelines according
to VDE 0100 resp. HD384 or IEC 60364 must be observed. The cir-
cuit breaker must be easily accessible to the user, and must be
identified as disconnect device for the unit.
