SMART ECO-MODE OPERATING.
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 stabi-
lization 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.
This operating mode is preset from factory as disabled and the
end-user can activate it if he needs it, according to section 7.3.2.
and Fig. 45.
The «Smart Eco-mode» operating mode is not available in
parallel systems.
6.8.
MANUAL BYPASS SWITCH (MAINTENANCE).
6.8.1. Operating principle.
The integrated manual bypass in the UPS is a very useful element,
but undue use can have irreversible consequences both for the
UPS or UPSs that make up the parallel system and for the loads
connected to its output. Therefore, it is important to respect the
manoeuvring over the switches as it is described in the following
paragraphs.
6.8.2. Transference to maintenance bypass.
To shift from normal operating to maintenance bypass:
• Shutdown the inverter.
Through the keypad of control panel
(3)
(see Fig. 40) and from
main screen press
(
)
key to access to «CONTROL AND STATUS
OF THE UNIT» submenu (screen 1.0), and then press
(
)
key. The
screen 1.3 will be displayed, asking you to shutdown the equip-
ment by pressing
(ESC)
. Do so, and then validate the operation
by pressing
(ENT)
. See the diagram of Fig. 39.
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.
•
In parallel systems meanwhile the inverters are started
up, if any manual bypass switch of the UPS or switch-
gear panel board is turned «On» by mistake, the power supply to
the loads will be shifted to the input or bypass mains, ON CON-
DITION that the electrical connections of the auxiliary contacts
of the manual bypass have been already done.
• Remove the screws
(t
2
)
that fixes the mechanical block
(BL)
of the manual bypass switch, located in the switchgear panel
board and take it out.
• Remove the screws
(t
2
)
that fixes the mechanical block
(BL)
of the manual bypass switch
(Q5)
of the UPS or each UPS and
take it/them out.
• Turn the manual bypass switch
(Q5)
of the UPS or each equip-
ment, to «On» position.
• Turn the manual bypass switch of the switchgear panel board
to «On» position.
• Turn the output switch
(Q2)
of the UPS or each equipment, to
«Off» position.
• Turn the output switch or switches of the switchgear panel
board, to «Off» position.
• Turn the switch-fuse holder of each battery cabinet
(Q8)
and/
or the switch-fuse holder or battery switch of the UPS or each
equipment
(Q3)
, to «Off» position
• In equipments or systems with separate static bypass
SLC
CUBE3+ B
:
Turn the bypass switch
(Q4a)
of the UPS or each equipment,
to «Off» position.
Turn the bypass switch or switches of the panel board to «Off»
position.
• For
SLC CUBE3+
equipments:
Turn the input switch
(Q1a)
of the UPS or each equipment, to
«Off» position.
Turn the input switch or switches of the panel board to «Off»
position.
The UPS or system is completely shutdown and out of service
(isolated), with the loads supplied from mains directly, through the
manual bypass of the switchgear panel board.
UPS or system with no panel board, the loads are supplied from
mains directly through the manual bypass of the equipments.
Power supply comes from the input line in
SLC CUBE3+
or static
bypass line in
SLC CUBE3+ B
.
6.8.3. Transference to normal operating.
To shift from maintenance bypass to normal operating:
• For
SLC CUBE3+
equipments:
Turn the input switch or switches of the panel board to «On»
position.
Turn the input switch
(Q1a)
of the UPS or each equipment, to
«On» position.
• In equipments or systems with separate static bypass
SLC
CUBE3+ B
:
Turn the bypass switch or switches of the panel board to «On»
position.
Turn the bypass switch
(Q4a)
of the UPS or each equipment,
to «On» position.
• Turn the output switch or switches of the switchgear panel
board, to «On» position.
