Note) Mass of grommet type. Add 10 g for conduit, 30 g for DIN terminal, and 60 g for conduit terminal type respectively. Also, add 60 g for VX31, 80 g for VX32 and VX33 respectively for bracket option. . Refer to “Glossary of Terms” on page 26, for details on the max. operating pressure differential and the max. system pressure.
