3.1 Mechanical Design
The electrical modules are installed in a plastic case with the dimensions 96 mm x 96 mm x 100 mm
(W x H x D). The case is prepared for mounting on a DIN rail.
The top side of the device accommodates the RJ45 Ethernet connector with 2 LEDs and 4 additional LEDs. At
the cover of the battery compartment there is a labeling strip for the configurable LEDs H1/H2 and a battery
symbol that indicates the polarity. The label is also located on the top side and provides among other informa-
tion the most important rated data of the device. A lithium battery is located under the removable cover of the
battery compartment.
The terminals for connecting all inputs and outputs, for the supply voltage and the protective grounding are lo-
cated on the terminal side. The number, type and position of the terminals differs according to device version
and is described in detail in chapter 5.3.
The snap-in unit is mounted in the center of the DIN rail side. The IP Addr. push-button is located in the lower
right corner of the DIN rail side. Pressing it (> 3 s) activates the factory-set default IP address. The default IP
address and the default subnet mask are imprinted on the side panel.
