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.
 For equipments with alphanumerical control panel.
Through the keypad of control panel (3) (see Fig. 42) 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 shut-
down the equipment by pressing (ESC). Do so, and then validate
the operation by pressing (ENT). See the diagram of Fig. 39.
 For equipments with touch screen control panel.

– The following «Pop up» message will be displayed, It asks to
the end-user if it he is sure about his selection
Are you sure ?
YES NO

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.
• 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. Those equipments with touch screen,
it will be shown in the flow diagram of main screen with the
icon.
• 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 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 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.
