can be followed:
1. Test the input and output terminals to ensure that the unit is completely isolated
from Mains and UPS
2. Remove the Covers from both sides of the UATS Shelf
3. Remove the four cable looms from the UATS, ensuring that you know where they
came from.
4. Replace the UATS Shelf
5. Wire the Cable looms into the replacement UATS and replace all of the covers.
6. Switch the UPS back on and check that it's working properly.
