Options
Startup with Battery If enabled, it allows the UPS to be started when there is a power failure
Restart If enabled, it allows automatic restarts
Output
Voltage It sets the output voltage value [V]
Frequency
It sets the output frequency value [Hz]
- Rated Value: it allows the output frequency value to be set (50 or 60
[Hz]) regardless of the supply voltage frequency.
- Automatic Select.: if enabled the UPS measures the input voltage
frequency and synchronises the output to the same value. If disabled
the UPS uses the Nominal Value as the setting.
Inverter (*)
It sets the output configuration and the load applied:
- Single-phase: just one single-phase output
- Three-phase 120°: three-phase output suitable for supplying
three-phase loads (e.g. a motor)
- Three separate phases: three single-phase output lines separate
from each other
Phases
at starting (**)
Phase L1
It allows to program for each output the starting
configuration:
- Always On: the phase is always on during starting;
- Always Off: the phase is always off during starting;
Last Status: phase restored to the state before shutdown
Phase L2
Phase L3
Input
PLL enabling
If enabled, the UPS synchronises the output sinusoid with that of the
input. If disabled, the output voltage is not synchronised with the input
and is signalled by the flashing of the status indicator (green)
PLL range
Allows you to select the frequency range in which the UPS
synchronizes output voltage with input voltage:
- NORMAL: UPS synchronizes to the frequency variations
of ± 2% of the nominal value;
- EXTENDED: UPS synchronizes to the frequency variations
of ± 14% of the nominal value;
- CUSTOM: set by user (see main menu);
Extended PLL range
If enabled, the UPS synchronises the output voltage with the input for
frequency variations of ±14% of the nominal value. If disabled, the UPS
synchronises for variations of frequency of ±2%.
Input Dip Enabling It allows to enable/disable input Dip function
7.2.2 UPS settings
(*) Available in the “Service Mode” only (**) Available only with 3 phase independent inverter
ATTENTION:
Please refer to paragraph 2.4 to set the CONFIG INVERTER parameter correctly.
° available when PLL range is set on CUSTOM option.
Note:
the PLL function sees to it that the unit’s output frequency is synchronised with the input frequency, guaranteeing
that the passage for zero occurs at exactly the same time. Hence, if activated, even if the bypass triggers (e.g. due
to an overload), the input-output synchronisation is always guaranteed.
ATTENTION
If the PLL function is disabled the automatic bypass function is disabled automatically as well. If the overload is
prolonged the UPS switches off (see “Overload permitted” in the Technical Description chapter).
