Activate the circuit breakers of the manual by-
pass board in the following order: Output, Input
and Bypass [devices version B, with independent
bypass line].
The LCD touch screen will light up and the rectifier pilot
light will initially light in red. The rectifier enters the
normal operating status (amber icon) and, after around
20 seconds, the rectifier indicator stops flashing and re-
mains green. After initialisation, the static bypass is ac-
tivated, supplying voltage to the output terminals from
the AC mains with the bypass indicator lit in green.

You can quickly see if the UPS status is NORMAL, LOW-
LEVEL ALERT (WARNING) or ALARM. They change in colour
and flashing frequency. Although both the colours and the
flashing frequencies of the RGB LEDs can be programmed,
by default they are as shown in .
6.3. OPERATIONS OF THE MANUAL BYPASS SWITCH
(MAINTENANCE).
6.3.1. Procedure to switch from normal mode to
maintenance bypass mode.
This procedure is applicable to transfer the load power from
the inverter output [Normal Mode] to the manual bypass switch
[Maintenance Bypass Mode].
Before performing this operation, read the display mes-
sages to ensure that the bypass power is stable [device
input voltage] and that the inverter is synchronised with the
bypass voltage. This is important to avoid the risk of inter-
rupting the power supply to the load.
1.
Click on the icon
BYP Transf.
"Inverter" indicator on the diagram will flash green and the
"Status" indicator will turn red. In addition, the acoustic
alarm will be activated. The load will be transferred to the
static bypass and the inverter will be set to standby.
To silence the acoustic alarm, click on the
the "Status & Ops" menu. This action cancels the au-
dible alarm, but does not delete the warning message on the
screen, which disappears when the alarm condition ends.
2.
Remove the mechanical lock of the manual bypass switch
from the external panel and switch it to "On". The load will
be fed directly from the mains via the manual bypass.
When a protection board is provided instead of a manual
bypass, the mechanical bypass lock must be removed, at
the back of the cabinet, and the bypass switch set to "On",
as this switch will not be located in the switchboard. It is
recommended in this operating mode [Bypass mode] and
condition [manual bypass board defect] to perform the fol-
lowing actions:
Remove the fixing screws of the lateral trim strips.
ˆ
Remove the fixing screws of all MPs and MBS.
ˆ
Slightly pull the handles on each one until they are pro-
ˆ
truding by about 4-5 cm from their housing in order to
unplug them from their connector on the backplane of
the device.
Before any change of operating mode and after car-
rying out the possible corrective actions, it is neces-
sary to correctly insert the modules to their original position
and fix them with their screws.
3.
Switch the protection or the battery circuit breaker of the
battery cabinet to the "Off" position.
4.
Switch the circuit breakers of the manual bypass board to
the "Off" position in the following order: Output, Input and
Bypass [devices version B, with independent bypass line].
5.
Initiate the necessary maintenance tasks.
