10.3 Information for use in damp conditions
The following information is intended to help when installing and operating the product in damp conditions.
1. Cables and pipework must be laid so that condensate or rain water that remains on the pipework/cables cannot enter the
screw fittings of the product's M12 plugs.
2. Check that all cable glands of the M12 plugs and the fittings are mechanically secured.
3. In case of doubt, the housing protection class should be increased with an exhaust air duct to areas free from moisture. To
accomplish this, equip the provided venting connection with suitable pneumatic connections to discharge the exhaust air in
a targeted manner via a pneumatic line. Ensure that the ventilation line is always depressurized, that it is not operated with
throttles, filters or similar components, and that it is laid in such a way that moisture cannot flow back.
