The max. permissible ambient temperatures depending on the temperature classes are
specified in the following tables.
Category 1G equipment Category 1G equipment Category 1G equipment Category 1G equipment
For applications requiring equipment category 1G, the process pressure of the media must be
between 0.8…1.1 bar. With the stated permissible ambient temperatures, the 80% consideration
of section 6.4.2/EN 1127-1 is taken into account. The application conditions in areas without
hazardous mixtures are specified in the manufacturer information.
Category 1/2G equipment Category 1/2G equipment Category 1/2G equipment Category 1/2G equipment
For applications requiring equipment category 1/2G, the process pressure of the media must be
between 0.8…1.1 bar. With the stated permissible ambient temperatures, the 80% consideration
of section 6.4.2/EN 1127-1 is taken into account. If OPTIBAR * 5060 VGK5/6/D*A/W C/U/0/H/T are
operated at temperatures higher than those specified in the table above, please make sure by
means of appropriate measures that there is no danger of ignition from the hot surface. The
maximum temperature on the electronics/housing should not exceed the values stated in the
table above. The application conditions in areas without hazardous mixtures are specified in the
manufacturer information.
