Functional description
The block diagram shows the functional design of a JOVYCUBE UPS. It normally comprises several
parallel switched single modules. The "ICB", "MBCB", "BCB" and "OCB" switches are used to start and
shut down the UPS as well as to switch over to the bypass. Additionally, for maintenance purposes the
battery can be disconnected from the UPS. The drawing includes the optional static bypass (smart
bypass).

2.1.1
UPS module
One UPS module on its own in fact provides all the functionality of a conventional UPS system, including
a rectifier, inverter and battery charger.
The main benefit of these UPS modules lies in their hot-pluggable and hot-swap capability.
This means that in live operation you can plug additional modules into the UPS cabinet, provided there
are free slots available, and remove modules from it, provided the power supply of the remained
modules is sufficient.
