Note: The cable connected to BCB port X102 must be routed separately from the power cable. It uses dual-insulated
shielded cable (the CSA is generally 0.5mm

when the wiring distance is 25m ~ 50m length), and the two
ends of the shield must be connected to the enclosure securely. The separate safety earth must be connected
between the UPS and BCB box.
Caution
If the corresponding functions are not required, simply leave the corresponding ternimals unconnected.
