split shroud installation will not interfere with or pinch the cables.
3. Position the lower split shroud below the meter body with the arch cutout aligned
with the body cylindrical shape.

4. Lift the lower shroud aligning the four studs of the lower split shroud into the slot of
the upper split shroud. When correctly aligned, fully engage the lower split shroud
with the upper split shroud in the slots of the upper shroud.
5. Install one split shroud clamp onto a lower shroud stud. Align the angled tabs of the
clamps to fit over the angled tabs of the upper shroud. Secure the clamp in place
using a hex nut with attached external tooth lock washer.
6. Tighten the nut with a 7/16 (11 mm) wrench. Repeat this at each of the stud
locations using additional nuts.
7. If required, attach the security wire seals on the Transmitter Enclosure end caps and
through the hex head bolts on the Base Enclosure and if required, install security
seals on the split shroud. Refer to
for detailed sealing instructions.
This completes the split shroud installation procedure.
