• battery test of a single UPS (individual): it is a control command
for a UPS that it is running in a parallel system currently , to make
a battery test equipment by equipment.
• battery test of parallel UPSs: it is a control command of all parallel
UPS, to make the battery test in all the equipments that made it
up.

(see figure 39).
This submenu shows the serial number of the UPS, firmware ver-
sion and model of the equipment.

Setting submenu
• This submenu is exclusively reserved for Service and Technical
Support or authorised personnel and it is only accessible by pass-
word.
Some settings modify the specifications and settings to activate
or deactivate some functions. wrong modifications and/or set-
tings can make possible faults or lack of protection to the own
UPS and even they can affect or damage the load/s, battery or the
own equipment directly.
• Almost all the settings can only be done meanwhile the UPS is on
bypass mode.

Special functions
The UPS has some special functions, that could satisfy a special ap-
plication of the user.
in case you require any of these special functionalists, contact the
KESS Support-Team to change the standard configuration from fac-
tory.
6.4.1.
operating on ECo mode
6.4.1.1. Short description of the ECo mode
• "ECo mode" function allows supplying the load/s from mains di-
rectly, through the internal filters only, meanwhile the energy is
inside the limits, so the UPS allows an "Economy mode" with high
efficiency > 97%.
• when mains is out of tolerances (voltage and/or frequency), or
there are mains failures or blackouts in the power supply, the UPS
will transfer to "normal mode" or "battery mode" depending on
the case and the load/s will be supplied in a safety way.
• nevertheless, the disadvantages are:
load can't be protected at 100 %, because on "line mode"
the load/s are supplied from commercial mains directly and
through the internal filters of the bypass.
The transfer time of the "ECo mode" to "battery mode" is
10ms approximately.
Therefore, this function is not suitable for some sensitive loads or
areas with unstable power supply.
6.4.1.2. To establish the ECo mode function
• The function can be activated or deactivated through the “Set-
ting” submenu (see section 6.3.7).
6.5.
operating as frequency converter
6.5.1.1. Short description of the frequency converter
function
• in the converter mode, the static bypass is disabled and any of the
operating modes of itself, because the input and output frequen-
cies are different (50 or 60 Hz). when input mains fails, either due
to a blackout or wrong, the equipment will transfer to “battery
mode” to supply the load/s properly.
• The output frequency is set to the preset value and required by
the loads. nevertheless, the contra is the capacity of the UPS,
which is derated up to the 70% of the nominal in the "Converter
mode”.
6.5.1.2. To establish the Converter mode function
• The function can be activated or deactivated through the “Set-
