7.6 Battery Protection
IM P O R T A N T ! Users m u st ch o o se appro priate switch in g devices to pro tect th e battery fro m sh o rt
circu it an d o verlo ad, etc. W e reco m m en d u sin g th e Vertiv B CB to pro vide a m o re perfect so lu tio n .
The battery is connected to the UPS through the BCB. The BCB is manually closed and has an electronic tripping device
controlled by the UPS control circuit. If the battery adopts rack mounting (or is far away from the UPS cabinet), the BCB will
be installed close to the battery, and the wiring distance of the power and signal cables connected to the UPS shall be
minimized.
The BCB has the following features:
•
Isolation
•
Short circuit protection
•
In case the inverter is locked by battery under-voltage the switch automatically disconnects to avoid the
damage of battery over-discharge
•
If equipped with a remote EPO button, can use the EPO button to remotely disconnect the BCB
•
Protection of mis-operation
To obtain the required backup time, the batteries may be connected in parallel. In this case, each battery string must be
connected to a separate BCB.
