SPS Installation and Maintenance Manual
Figure 13. Frangible Coupling
6.
Caution: The following steps should be performed by 2 people.
7. One person should support the SPS while the other person removes the 4
bolts attaching the SPS to the mounting base.
8. Lift the SPS off of the mounting base bolts, and support the SPS on the
mounting base, next to the bolts.
9. Pull the wind cone power cable out of the SPS mounting leg.
10. Using a pipe wrench, remove the frangible coupling from each of the 2
SPS legs.
11. Using pipe wrenches, separate the 2 flanges from each of the frangible
couplings. Discard the old frangible couplings.
12. Thread a new frangible coupling on to each of the 2 mounting legs.
13. Thread a flange on to each of the 2 frangible couplings.
14. Tighten each flange and frangible coupling to each mounting leg. After
tightening, make sure the holes in each flange align with the bolts on the
mounting base.
15. Reinstall the wind cone power cable through the mounting leg, and into
the battery enclosure.
16. Lift the SPS on to the mounting base, while guiding the mounting legs on
to the 4 mounting bolts. Install a lock washer and nut on to each of the 4
mounting bolts.
17. The bottom nuts on the mounting bolts are used to level the SPS. Place a
level on the top surface of the battery compartment, and adjust the 4
bottom nuts until the battery compartment is level in all directions.
18. Tighten the top nut on each of the 4 mounting bolts to secure the SPS to
the mounting base.
19. Reconnect the wind cone power cable, using the procedure described in
Section 4.3.4.
20. Install the fuses, using the procedure described in Section 4.3.6.
21. Reinstall the battery enclosure cover.
