5.2 Installation of the Modules
Installation options
The OLM modules can either be mounted on a 35 mm rail according to DIN EN
50022 or on a flat surface with the help of a mounting plate.
¾ Choose the location so that the climatic and mechanical limit values listed in the
technical specifications can be met.
¾ Make sure there is enough space to connect the bus and voltage supply lines.
¾ Connect the fiber-optic cables before you install the modules. This makes it easier
to connect the fiber-optic cables.
¾ Only install the modules on a rail or a mounting plate that is grounded with low
resistance and inductance. No other grounding measures are necessary.
