5 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
Mounting variants
wrong
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�
6 Electrical connection
To guarantee the electrical interference protection of the module, the hou-
sing 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 hea-
ting of the unit, the respective minimum rated temperature of the connection
cable must be taken into account�
6.1 M12 sockets
►
Use sockets with gold-plated contacts�
►
Use protective caps (supplied) for unconnected connectors of the I/O module�
6.2 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�
6.3 M16 cable gland
Use a suitable cable to ensure ingress resistance of the M16 cable gland�
