Note 2) Weight of grommet type. Add 10 g for conduit type, 30 g for DIN terminal type, 60 g for conduit terminal type respectively. �� Refer to “Glossary of Terms” on page 139 for details on minimum operating pressure differential, the maximum operating pressure differential, maximum system pressure.
