NOTE:
The metallic alloy used for the enclosure material may be at the accessible surface of
this equipment; in the event of rare accidents, ignition sources due to impact and
friction sparks could occur. This shall be considered when the 2130 is installed in
locations that specifically require Class 1, Div 1 equipment.
7. It is the responsibility of the user to ensure:
a. That the joint requirements between the switch and the vessel tank are
compatible with the process media.
b. That the joint tightness is correct for the joint material used.
8. The switch fork is subjected to small vibration stresses as part of its normal
function. As this provides a partition wall, it is recommended that the fork should be
inspected every 2 years for signs of defects.
9. It is the responsibility of the user to ensure that only suitably certified cable entry
devices will be used when connecting this equipment.
