During the transfer of the load on the inverter from ECO
mode, a small interruption (less than 10ms) occurs. It is
very important to ensure that the critical load fed into this UPS
mode, tolerates that interruption time.

4.3.3.6. Status - Frequency converter (CF) mode.
When operating in this mode, activated in the configuration,
the device supplies a fixed output frequency of 50 or 60 Hz,
which may be different from the input power frequency. When
operating in this mode, the UPS's static bypass is inhibited and
the manual bypass switch should not be operated, due to the
consequences this could have on the loads connected to the
output.

4.3.4.1. Basic functions.
Charging at constant
•
The battery charge current corresponds to the formula
I = Kc x C, where Kc is a configuration parameter with a
ch
value between 0.01 and 0.3.
The UPS is designed to provide 100% of its rated power
to the load and additionally has a unique reserve power to
charge the batteries that can be set between 0 and 20% of
the rated power of the UPS, depending on the capacity of
the batteries and the charging current.
Fast charging at constant
•
This voltage can be adjusted according to the requirements
of the battery type. For example, for valve-regulated lead-
acid batteries (VRLA), the maximum fast charge voltage
should not exceed 2.4 V / cell.
Float charging.
•
The float voltage can be adjusted for the type of batteries.
For -VRLA- batteries, the float voltage must be between
2.2 V and 2.3 V. By default it is set to 2.25 V.
Compensation of the floating voltage according to
•
temperature.
The compensation value of this voltage can be adjusted ac-
cording to the temperature and type of batteries. To do so,
it is necessary to install the supplied temperature sensor in
the battery cabinet. The compensation range per cell is 0 to
5 mV / ºC and the default value is 3 mV / ºC.

4.3.4.2. Advanced functions.
Low battery alarm.
•
The low battery alarm is activated prior to the end of dis-
charge -EOD- alarm. When activated, it has a few minutes
of backup at full load.
End of discharge protection
•
When the battery voltage reaches this minimum value, the
accumulator block is disconnected to avoid the deep dis-
charge that could irreversibly damage them. There are two
voltage levels of end of discharge and the actual is calcu-
lated by interpolating the following two values:
-EOD- Voltage / Cell @ 0.6 C Discharge current. By de-
ˆ
fault 1.65 V / cell.
-EOD- Voltage / Cell @ 0.15 C Discharge current. By
ˆ
default, 1.75 V / cell.
The end of backup voltage values are factory configurable
from 1.6 to 1.75 V / cell.
Battery protection disconnection alarm
•
This alarm will be available when using the mechanism
provided for the external batteries, a circuit breaker -MCB-
with an auxiliary contact. The alarm will be activated if the
battery protection -MCB- is switched off.
