4.4.3. Normal operating with Peak Shaving (
With mains present, in a similar way to section 4.1.1, the rectifier
converts the AC input voltage into DC, but only providing
power to the DC bus up to the set limit. The rest of the power
that the inverter needs is obtained from the battery group.
In the event that, in this situation, the end of autonomy of the
batteries is reached (minimum discharge voltage level), the
equipment will stop the inverter, and will connect bypass voltage
to the output or not, depending on the configuration parameter
chosen by the user.
For the network return, the behavior is similar to that described in
4.4.2, also acting the "Walk-in Time" and the "Walk-in Delay".
4.4.4. Operating with non-active inverter ().
The inverter is non-active due to alarm conditions like overloads,
over temperatures, etc... In this case the rectifier is still charging
the batteries in order to keep their optimal charge status.
The inverter is also non-active if the start up has not been done
through the keypad of the control.
In both cases, the output voltage of the UPS comes from the emer-
gency bypass line through the static bypass switch (Fig. 25 and 26),
on condition that the EPO is inactive.

). 4.4.5. Manual bypass operating ().

When it is required to make any maintenance service to the equip-
ment, it can be disconnected from mains without breaking the
power supply of the system and affecting it to the critical load.
The UPS can only be intervened by technical or maintenance staff,
by means of the manual bypass switch (respect the corresponding
operative instructions later on stated).
4.4.6. Frequency converter operating.
The SLC CUBE3+ PS
converters, always incorporating batteries, being able to operate
from 50 to 60 Hz or vice versa.
In equipment configured as frequency converters, there is no static
bypass or manual bypass.
Consequently, all functions, readings, alarm messages, parameter
settings, as well as related switch operations will not be applicable
or operational and will not be taken into account.
can be factory configured to work as frequency
