7.10 BCB Cabinet (Optional)

The UPS has three kinds of BCB matching cabinets, and the user can choose the cabinet you need according to actual
requirement. The BCB cabinet can also electrically isolate the UPS from the battery to minimize the danger of the service
personnel at work.

The BCB provides the following functions:

•

Short circuit protection and EOD protection. The BCB opens automatically when the battery voltage drops to
the EOD voltage point.

•

Support the UPS EPO function. The BCB opens automatically when the EPO switch on the touchscreen of the
UPS is pressed.

Overall BCB cabinet

One 1600 A switch included for single battery string use or bus switch of several battery strings.

Divided BCB cabinet (three independent switches included)

connection of each battery string.

Divided BCB cabinet (four independent switches included)

T able 7.3 P aram eters o f B CB cabin et

The BCB cabinet should be installed as close as possible to the battery. It can be installed on a horizontal surface.

Besides the local regulations, to enable routine operation of switches in the BCB cabinet within the BCB cabinet, it is
recommended that clearance around the front of the UPS should be larger than 1200 mm and enough to enable free
passage of personnel with the door fully open. Meanwhile, maintain a clearance of at least 500 mm at the back of the
cabinet to permit adequate circulation of air coming out of the UPS.

To install and connect the BCB cabinet refer to Figure 7.3 on the next page to Figure 7.7 on page 137. There are connection
terminals in the BCB cabinet for connecting the power cables from the UPS and battery. Before powering on the UPS, lead
out the internal signal cables from the BCB cabinet to connect the left port of J22 on the bypass control module.
