3 Mounting

To protect the module against mechanical stress it must be mounted so that it
lies completely flat on an even mounting surface. To do so, three cylinder screws
with hexagon socket (M5 x L) to DIN 912 or DIN 7984 must be used.
preferred
To avoid contact corrosion between the mounting screws and the module
housing, do not use any stainless steel screws or nickel-plated
screws!
In very corrosive environments such as extremely salty air, we recommend
to use screws with surface finishing on a zinc/nickel basis with thick-film
passivation and sealing. For normal corrosive requirements zinc-plated
screws are sufficient.

4 Electrical connection

To guarantee the electrical interference protection of the module, the
housing must be connected to GND (e.g. to the ground of the vehicle).
Due to the maximum operating temperature of 85 °C and the internal
heating of the unit, the respective minimum rated temperature of the con-
nection cable must be taken into account.

4.1 M12 sockets

Use sockets with gold-plated contacts.
Use protective caps (supplied) for unconnected connectors of the I/O module.
4.2 Tightening torque of the cover screws (terminal chamber)
To close the terminal chamber the cover screws are tightened with a tightening
torque of 1.2 Nm.
