The eWON must be fastened on a 35mm DIN rail compliant with EN50022. A fixing latch is therefore fastened at the
bottom of the housing in order to put the device in place or remove it.
To put the unit in place, insert the top slider into the upper part of the rail, with the eWON tiled around 20°. Then
draw the latch at the bottom downwards with a screwdriver and at the same time put the unit right by rotating it.
Release the pin, the eWON is now safely fastened.
Important: Be careful when mounting the unit on the DIN-rail as doing it improperly could damage either
the fixing latch and/or the DIN-rail itself.
