4. Only be connected to the certified associated
apparatus, the Vortex Flowmeter could be used in the
explosive atmosphere. The connection should be
complied with the requirements of the manual of the
associated apparatus and the Vortex Flowmeter.
5. The enclosure should be taken to protect it from
impact.
6. Any friction should be prevented in order to avoid the
risk of electrostatic charge on the enclosure due to
non-conductive paint.
7. The cable with shield is suitable for connection, and
the shield should be connected to earth.
8. The enclosure shall be kept from the dust, but the
dust shall not be blown by compressed air.
