Rectifier startup and
shutdown.
All of the protections or disconnectors of the system must be
in the 'Off' position and, in particular, that of the the batteries
of the device(F/Q3) and its counterpart (F/Q8) in the accumu-
lator cabinet, when it has an external battery bank.
Since the fuses of the disconnectors are supplied al-
ready installed to prevent them from being lost or mis-
laid, it is important to check that the disconnectors are open
(Off).
Check that the instructions in Chapter 7 of Installation have
been followed.
With the loads in standby, apply mains voltage to the input
terminals:
ˆ Single-phase devices.
Main power supply network terminals (X1) and (X4).
Auxiliary power supply network terminals (for TSS)
(X1A) and (X4A).
ˆ Three-phase devices.
Main power supply network terminals (X1), (X2) and
(X3).
Auxiliary power supply network terminals (for TSS)
(X1A) and (X4A).
Notes regarding types of battery charging.
ˆ Quick charging is carried out automatically when the rec-
tifier is started. Under normal working conditions and if
the batteries are not at 100%, quick charging is activated
until the level is reached.
When a mains failure occurs, the batteries discharge to
a greater or lesser extent. When the mains return, quick
charging is activated automatically.
Quick charging can also be started manually via the control
panel with LCD display (see Screen 2.2 of Fig. 17).
Cyclically, every 6 months, counted from the last activa-
tion, quick charging is activated either automatically or
manually.
ˆ Exceptional charging.
Exceptional charging is forced manually at the will of the
operator via the control panel (see Screen 2.3 of Fig. 17).
8.1.
Startup procedure
Set two-pole battery disconnector with fuses (F/Q3) to 'On.'
In systems with accumulators in a separate cabinet, set two-
pole battery disconnector with fuses (F/Q8) to 'On.'
Set general input switch (F/Q1A) to 'On.'
ˆ In three-phase rectifiers:
If the following alarm message appears on the control
panel display...
PHASE ROTATION ERROR
.. an audible alarm will also sound and the device will not
be able to start, as the input phase sequence will be in-
correct.
SALICRU
ˆ If this occurs, set general input switch (F/Q1A) of the de-
vice and its switch on the protections panel to 'Off.'
Swap two of the phases on the input terminals and repeat
the startup process described so far.
Set general two-pole output switch (F/Q2) to 'On.'
The system is operational.
Start the loads.
8.2.

Shutdown procedure.

Stop the loads.
Set general two-pole output switch (F/Q2) to 'Off.'
Set general three-pole input switch (F/Q1A) to 'Off.'
In systems with accumulators in a separate cabinet, set two-
pole battery disconnector with fuses (F/Q8) to 'Off.'
Set two-pole battery disconnector with fuses (F/Q3) to 'Off.'
The system is completely out of service.
