After you install the BCB box, adjust the end of discharge (EOD) threshold based on backup
time, which prevents overcurrent disconnection. The default values are as follows:
Backup time < 1 h: Set the EOD threshold to 1.67 V/cell.
3 h > Backup time ≥ 1 h: Set the EOD threshold to 1.75 V/cell.
Backup time ≥ 3 h: Set the EOD threshold to 1.80 V/cell.
Step 3
(Optional) Install a BBB box.

3.2.5 UPS Cable Connection Reference
Context
Keep away from cabinets when preparing cables to prevent cable scraps from entering the
cabinets. Cable scraps may cause ignition during power-on and result in personal injury
and device damage.
After installing cables, clean the cabinet top, bottom, copper bar wiring positions, and
other positions. Ensure that there is no dust or scraps inside and around cabinets.
Prepare terminals onsite. The length of the copper wire should be the same as that of the
part of the terminal that covers the conductor.
Procedure
Step 1
Route a cable into the cabinet and bind it to a nearby beam.
Step 2
Pull the cable to the copper bar to which the cable is to be connected, determine the cable
length, and mark the cable at the position where the cable is to be cut.
Step 3
Pull the marked cable out of the cabinet, cut the cable from the marked position, strip the
cable, and crimp a terminal.
