4.5 OPERATION IN GE CONFIGURATION.

With a generator, the frequency and voltage ranges of the auxiliary mains can be increased to accept the instabil-
ity of the GE and at the same time to avoid operation from the battery or risks of out-of-synchronisation switching
onto the bypass.
The use of the GSS interface, described in the options section, also increases the amount of diagnostic information
exchanged between the continuous power system and the generator.
4.6 “ENERGY SAVER” MODE.
This mode ensures that the UPS system always operates at the highest load efficiency (40-70% of the nominal
power).
This mode can only be activated on UPS connected in parallel and operating in normal mode.
In cases of low load, the system shuts down any unnecessary UPS units, thus increasing the load on the remaining
units.
This leads to higher system efficiency, as the UPS in stand-by are not using any power, while the active units with a
high load are operating at maximum productivity.
When the load increases, the units in stand-by are immediately reactivated to guarantee continuous power supply.
Monitoring the hours of operation means that the hours are distributed on all the UPS, alternating the units that are
shut down from time to time. This prolongs the life of the units and reduces the risk of failure.
