8. Two cabinet attachment brackets are provided for securing each cabinet at the top and
bottom. A flat bracket joins the top of the cabinets and a larger flat bracket joins the
cabinets at the bottom. Attach the flat bracket to the cabinet tops first.
9. Remove the left-hand and right-hand screws from the adjacent top door hinges of the
battery cabinets. Align the holes in the small flat bracket from the field kit over these
screw holes. Replace the screws in the hinges, securing the bracket to the cabinets.
10. Locate the large flat bracket from the field kit. Place the bracket over the bolts on the
bottom side of the adjacent lower hinges on the battery cabinets.
11. Secure the bracket to the hinges with hardware from the field kit.
12. Route the ground wire (from the field kit) from the ground stud in one battery cabinet,
under the lower battery tray and through the cabinet to cabinet cable access area in the
side of the cabinets, and attach to the ground stud in the other battery cabinet. Hardware
is provided on each ground stud.
13. If installing additional battery cabinets, repeat Steps 5 through 12 to join each additional
battery cabinet; otherwise, proceed to Step 15.
14. If not already installed, mount the hanger brackets to the top appropriate side of the last
battery cabinet using M4 screws.

4.3.4 Separate Battery Cabinet Electrical Connections
Use this procedure to wire a separately located battery cabinet to the UPS cabinet. All battery
cabinets will arrive at the site with each battery connection string electrically disconnected. If
you are installing more than one battery cabinet, the first battery cabinet will be the only cabinet
directly connected to the UPS.
1. Locate the battery breaker sensing cable in the right-hand battery cabinet. Route this
connector into the cabinet to the immediate left and mate with the matching connector in
that cabinet.
2. Locate the battery wiring harness under the bottom tray in the right-hand battery cabinet.
Route this harness into the cabinet to the immediate left and connect to the (+) lead to
the (+) battery terminal and the (-) lead to the (-) battery terminal.
3. Repeat Steps 1 and 2 for each battery cabinet, and then proceed to Step 4.
4. Refer to the wiring diagram to connect the external wiring from the first battery cabinet
to the UPS cabinet.
5. Locate the UPS-to-battery cabinet breaker sensing cable inside the first battery cabinet.
Mate the connector on this cable with the matching connector in the cabinet. Route the
other end of this cable through conduit (top or bottom entry) to UPS cabinet and connect
to terminal strip TB2.
6. Connect and route cables from positive (+) and negative (-) terminals in the bottom of
the first battery cabinet through conduit (top or bottom entry) to UPS cabinet terminals
E4 and E5.
