13.2 Information for use in damp conditions
The following information is intended to help when installing

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 fit-
tings are mechanically secured.
