2. The equipment is not capable of withstanding the 500 V electrical
strength test as defined in clause 6.3.13 of EN 60079-11:2012. This
must be taken into account during installation.
3. The measured capacitance between the equipment enclosure and
metallic conduit adapter is 21pF. This must be considered only when
the Model 781S is integrated into a system where the process
connection is not grounded.
