5.3.4 Resetting the history log

The history log can be reset by entering the HISTORY RESET section; the operation
requires a further confirmation.
Loss of data
The alarms history contains very important data to monitor the device behaviour over
time. We recommend to save the data before deleting it.

5.3.5 Setting the RS485 user interface parameters

The parameters regarding the communication via RS485 interface can be set in the
MODBUS RS485 section.
This section allows to set the ModBus address, the communication mode and the data
transmission speed.

5.3.6 New battery

The page NEW BATT is used in case battery circuit breaker BCB is not closed, when
requested, in the start-up phase. In this case the system will start considering the battery
completely discharged and activating the alarm "A10 – BATTERY FAULT".
To set the battery autonomy to 100% it is necessary to access the section and confirm the
operation in the confirmation page.
In case of distributed battery configuration such section is disabled and can be found in the
Settings section of each power module.

5.3.7 Setting the battery

In case the UPS has been tested without knowing the characteristic data of the storage
battery, the BATTERY SETTING section allows to set such data. Each single settable
parameter can be accessed via the following page.
