This is important to maintain the ingress protection level and the integrity of the flameproof enclosure.
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 IS
installation. Never install a device, which was previously installed without an intrinsically safe barrier, in an intrinsically safe system.
In non-incendive installations, check to ensure that all the electrical connections are made to approved circuits which meet local and jurisdictional
installation codes.
Verify that the markings on the label are consistent with the application.
