Before connecting cables, check that the BCB box has been installed properly and that the
circuit breaker on the BCB box is OFF.
Take protective measures, wear insulated gloves and shoes, and stand on the insulated pad
when connecting cables.
Do not simultaneously touch positive and negative terminals to avoid electric shocks when
connecting battery cables.

The BCB box is wall-mounted or rack-mounted. Cables are routed in from the bottom and
out from the top. Reserve sufficient space on the top and bottom of the BCB box.

two cables are routed from batteries or the UPS to the same wiring terminal on the BCB
box, crimp the cable on both sides of the terminal.
Connect cables according to terminal silk screen and wiring diagrams in this document.
