Chapter 4 Joining the Cabinets
If you are installing additional cabinets to the UPS, join the cabinets before installing
the electrical connections between the cabinets.
To join the cabinets:
1. Position the cabinets to the left of the UPS, leaving enough space between
cabinets to remove the knockouts.
NOTE Position the Extended Battery Cabinet (EBC) to the far left of the UPS and Options Cabinet (if
installed).
NOTE A maximum of four EBCs can be installed.
NOTE If you have two Options Cabinets, position the cabinet with the maintenance bypass switch (MBS)
closest to the UPS.
2. Remove the front door of all cabinets (see pages 10 and 11).
3. For EBCs only or EBCs and Options Cabinets, continue to Step 4. For Options
Cabinets only, proceed to Step 8.
4. Remove the knockout on the top left side of the UPS and the top right side of
the EBC (see Figure 10).
If you are installing more than one EBC, remove both knockouts on the middle
cabinet(s).
5. If you are installing an EBC with an Options Cabinet, continue to Step 6;
otherwise, proceed to Step 11 to install the ground straps.
6. Remove both knockouts from the top sides of the Options Cabinet (see
Figure 10).
7. Remove one edge grommet from the inside rail of the EBC(s). Install the
grommet on the bottom edge of the left knockout of the Options Cabinet (the
knockout closest to the UPS does not need an edge grommet).
If you are installing two Options Cabinets, install edge grommets on both
knockouts of the second cabinet.
8. Remove the rectangular knockout on the right side of the Options Cabinet.
If you have two Options Cabinets, remove the rectangular knockout on the right
side of the second Options Cabinet.
9. Remove the three circular knockouts on the left side of the UPS (see Figure 10).
If you have two Options Cabinets, remove the three circular knockouts on the
left side of the first Options Cabinet.
10. Install three bushings (supplied) in the circular knockouts of the adjacent cabinet.
