COMPLETE SHUTDOWN OF THE UPS OR SYSTEM.
• Shutdown the loads.
• If the equipment or parallel system has an outgoing distribution,
turn its switches «Off».
• Shutdown the inverter of the UPS.
For equipments with alphanumerical display.
Through the control panel keypad (3) (see Fig. 42) and from
main menu, press the key () to access to the «CONTROL
AND EQUIPMENT STATUS» submenu (screen 1.0), and next
press the key (). The screen 1.3 will be displayed, where
to stop the equipment the key (ESC) has to be pressed.
Press the key and confirm the operation by pressing over
(ENT). See the diagram of Fig. 39.
For equipments with touch screen control panel.
– Touch over the «Status and control» icon
– Touch over the «Start/Stop UPS» icon
– The following «Pop up» message will be displayed, It asks to
the end-user if it he is sure about his selection
Confirm the action by touching over «YES».
In parallel systems is necessary to act over one of them
only.
Consider that the UPS or system is still supplying output
voltage through the static bypass.
• Turn «Off» the output switch or switches of the panel board.
• Turn the output switch (Q2) of the UPS or each equipment of
the system, to «Off» position.
• Turn the battery switch, battery protection or both elements
«Off», considering both available topologies and the established
order:
Equipments with a single battery mechanism, either with a
battery fuse holder switch or battery switch and labelled in
the figures of the present document as (Q3).
Equipments with two battery mechanisms, fuse holder
switch (F3) and switch (Q3):
1. Battery fuse holder switch (F3) first.
2. Next the battery switch (Q3).
In parallel systems, repeat the process in each equipment.
• For equipments with external battery cabinets, turn the fuse
holder switch of the battery cabinet/s (Q8) of each UPS to
«Off».
• In equipments or systems with separate static bypass line SLC
CUBE3+ B:
Turn the bypass switch or switches of the panel board, to «Off».
Turn the bypass switch (Q4a) of the UPS or each equipment of
the system, to «Off».
• Turn the input switch or switches of the panel board to «Off».
• Turn the input switch (Q1a) of the UPS or each equipment of
the system, to «Off».
• Break the input power supply of the switchgear panel. The
system will be completely deactivated.
•
Electrical discharge hazard. In case the battery
cabinets or racks are required to be disconnect from
UPS, wait several minutes (5 min. approx), till the electrolytic
capacitors have been discharged.

Emergency Power Off (EPO) is equivalent to a complete shutdown:
• UPS converter or all converters of the system are shutdown
(rectifier and inverter).
• No power supply is supplied to the loads.
The emergency power off (EPO) function can only be activated
through the two pins terminal strip (X50). In a parallel system, it is
not needed to make more connections than the ones done in a single
equipment, because through the communication BUS, any action
over the button will affect to the complete parallel system.

For those less critical applications, the smart and efficient function
«Smart ECO Mode», meanwhile the power supply is available, al-
lows supplying the loads from mains directly through the solid state
static bypass («Off Line» mode).
In case of power supply failure, the system will automatically shift
to its normal operating mode («On Line») and loads will be fed from
the inverter by the energy of the batteries. The «Smart ECO Mode»
operating mode has efficiency benefits like having between a 4 and
4.5 % higher than in normal mode «On Line», so it will be close to
the 100 %.
The «Smart ECO Mode» operating does not assure a perfect sta-
bilization in frequency, voltage or sinewave shape (distortion) as in
normal «On Line», because the figures of these parameters depend
on the static bypass line and its set limits completely.
The detection of any of these parameters can take up to 3 ms, so
it is recommended to assess the use of this operating mode, de-
pending on the required protection level by the loads.
To activate the ECO Mode function, proceed as follows:
• For equipments with alphanumerical control panel.
This operating mode is disabled from factory and the end-
