Series Use for 48V Applications
A series connection for 48V applications is allowed when using two individual
power supplies, two DC-UPSs and two battery modules.

Using the Inhibit Input
The inhibit input is a feature to disable the battery mode on purpose. This can
be the case when buffering should actively be stopped to save battery capacity
(for example, when machines are not in use for a long period) and to have
shorter recharging times or if there is a service event where the application
must be turned off.
Buffering can be inhibited or stopped:
- When a static voltage is applied to the inhibit input terminals, there
will be no buffering after the input voltage is switched off.
- When, during the battery mode, a short voltage pulse with a minimum
length of 250 ms is applied to the inhibit input terminals, the output
switches off and stay off until the input voltage recovers.
Batteries are charged when the inhibit mode is activated or a voltage is applied
to the inhibit input terminals. See
