All fieldboxes have a good resistance against chemicals
and oil. When used in aggressive media (e.g. chemicals,
oils, lubricants and coolants in high concentrations) the
material resistance must in each case be checked in
advance for the specific application.
The sum of the total current of the individual device ports
X0 – X7 for outputs A1 (power supply to devices) and DO
(digital output) should not exceed 850 mA.
Protection class IP67 is only reached if all M12 connectors
and blanking plugs, as well as the viewing window are
properly fastening with screws.
