Buffer components, maximum number and compatibility
A maximum of two buffer components can be used with a basic unit. Maintenance-free buffer
modules with integrated energy-storage device (electrolytic capacitors, double-layer
capacitors) are available as buffer components to buffer shorter power failures. There is also
a UPS module and battery modules (with lead or lithium iron phosphate batteries) as
external energy storage device to buffer longer power failures.

Note
It is possible to use different buffer modules in one system. This means that a buffer time of
400 ms (100 ms + 300 ms) can be realized, for example.

Note
Using SITOP BUF8600 and SITOP UPS8600 in one system
If a buffer module and a UPS module are used in a system, then the buffer module is first
charged, and in the buffer mode is the first to be discharged. After the buffer module has
been discharged, then the UPS module takes over the buffering. In the buffer mode, the
UPS module does not charge the buffer module that has already been discharged.
