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�
