3. When the equipment is installed, particular precautions must be
taken to ensure, taking into account the effect of process fluid
temperature, that the ambient temperature of the electrical
housing of the equipment meets the marked protection type
temperature range.
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. Users are forbidden to change the configuration to ensure the
explosion protection performance of the equipment. Any faults
shall be settled with experts from the manufacturer.
9. During installation, operation and maintenance, users shall
comply with the relevant requirements of the product instruction
manual, GB3836.13- 2013 “Electrical apparatus for explosive gas
atmospheres Part 13: Repair and overhaul for apparatus used in
explosive gas atmospheres”, GB3836.15-2000 “Electrical
apparatus for explosive gas atmospheres Part 15: Electrical
installations in hazardous areas (other than mines)”,
GB3836.16-2006 “Electrical apparatus for explosive gas
atmospheres Part 16: Inspection and maintenance of electrical
installation (other than mines)”, and GB50257- 2014 “Code for
construction and acceptance of electrical device for explosion
atmospheres and fire hazard electrical equipment installation
engineering”.
