Where the protection type depends on wiring glands, the glands must be certified for the type of
protection required.
The metal housing is a die-casting alloy, which is predominately aluminum.
Before powering the SVI II ESD:
1.
Verify that the pneumatic and electronic cover screws are tightened. This is important to
maintain the ingress protection level and the integrity of the flameproof enclosure.
2.
If the Installation is Intrinsically Safe, then check that the proper barriers are installed and the
field wiring meets local and national codes for an I.S. installation.
Never
install a device, which
was previously installed without an intrinsically safe barrier, in an intrinsically safe system.
3.
Under normal operation, compressed supply gas is vented from the SVI II ESD to the
surrounding area, and may require additional precautions or specialized installations.
4.
If the Installation is Non-Incendive, then check that all the electrical connections are made to
Approved Devices and wiring meets local and national codes.
5.
Verify that the markings on the label are consistent with the application.
6.
Verify that the air supply pressure can not exceed:
a.
For Single Acting 100 PSI (6.8 Bar)
