Figure 2. Connection Detail
2. Place the new IS Barrier assembly into position on the front cover. Secure using the existing screws.
3. Plug the IS Barrier assembly into the mating connector attached to the Main PCBA.
4. Inspect and clean the machined flange joint surfaces of both the cover and the box. Surfaces must be
smooth, free of nicks, scratches, dirt or any foreign particle build-up that would prevent a proper seal.
Surfaces must seat fully against each other to provide a proper explosion-proof joint. Clean surfaces
by wiping with a clean, lint-free cloth.
5. Apply a light coat of Killark “LUBG” lubricant to flange surfaces and close the cover. Install and
tighten all cover bolts to 30 ft-lbs. Make certain no cover bolts are omitted. Use only those bolts
supplied with the enclosure.
6. Insure proper grounding to protective earth.
7. Reapply power to the station.
