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 page 10).
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.
