NOTE:
There may have two identification plates, if there is double
approval (VG9_XE6_) asked. When the device is installed,
remove the identification plate which is not valid. If device
is installed to Ex d area, it can't be installed to Ex i area any-
more even if identification plate is changed.
Ex NOTE:
This manual contains technical specifications for sev-
eral types of the ValvGuard. If in doubt, refer to the
type approval certificate of the respective version.
The certificate is delivered with the field device and is also
available from the manufacturer.
