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).
In panel flush mounting devices, the display side accommodates the display, 4 softkeys located below and 4
LEDs of which the H1, H2, and ERROR LEDs can be parameterized. The ERROR LED can only be
parameterized for error messages.
The device top side holds the RJ45 Ethernet plug connector with 2 LEDs. 4 additional LEDs are identical to the
LEDs on the display side. 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 information the most important rated data of the device. A lithium battery is located under
the removable cover of the battery compartment.
SICAM P850/P855 devices can also contain a D-sub connector plug as RS485 interface (see Figure 3-1) as
shown in the ordering information (see Chapter 2.2).

DIN rail devices have a DIN rail support instead of the display. Therefore, this device side is referred to as the
DIN rail side.
