to 130 kW, the system indicates an overload condition, because the redundant module is not
taken into account in calculating the UPS’s maximum output capability.
When modules are added to the system or removed from the system, the value of
total number of modules must be adjusted. You may or may not at that time also
want to change the number of redundant modules.

8.2.1.3.1.
Model type
Indicate the maximum output power of your system. Here, assume no redundant modules, so that
all modules are considered when calculating the maximum potential system output.
This factory default setting should not be changed.
8.2.1.3.2.
Multi-system mode
Indicate that the UPS will be operating in parallel configuration (multi-system mode).
A password may be required to modify this setting. If you do not have the appropriate password,
contact your distributor or sales agent.
8.2.1.3.3.
ECO mode
In ECO mode (also called standby mode), under normal conditions the load is powered from the
bypass line. In the event of a problem with the bypass input, the load is transferred to the inverter.
ECO mode can result in an energy savings of at least two percent, because the inverter is used
much less than it would be otherwise. This is at the expense of a small increase in the possibility
of the load being subject to irregularities in the input voltage, during transfer of the load from the
bypass line to the inverter. In the decision to use ECO mode or not, much depends on the normal
quality of the mains voltage and on the sensitivity of the load.

Enabled
Make a checkmark here enable the ECO mode function on the UPS.
Analyse grid
Checkmark this field if you want the UPS software to decide the reliability
of the mains voltage.
Custom reliability
Indicate your judgement of how reliable the mains voltage is.
If you have selected the “Analyse grid” option, the UPS software may
change the reliability later based on its observations.
