8. 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
(Q3)
and its counterpart
(Q8)
in the accumulator
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 mislaid,
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 mains terminals
F, N
.
ˆ
Three-phase devices.
–
Main mains terminals
R, S, T, N
.
• Notes regarding types of battery charging.
ˆ Fast charging is carried out automatically when the recti-
fier is started. Under normal working conditions and if the
batteries are not at 100%, fast 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, fast
charging is activated automatically.
Fast charging can also be started manually via the con-
trol panel with LCD display.
Cyclically, every 6 months, counted from the last acti-
vation, fast 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.
8.1. Startup procedure.
•
Set battery circuit breaker
(Q3)
to ‘On’.
•
In systems with accumulators in a separate cabinet, set two-
pole battery disconnector with fuses
(Q8)
to ‘On.’
•
Set general input switch
(Q1)
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.
ˆ
If this occurs, set general input switch
(Q1)
of the device
and its switch on the protection board 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
(Q2)
to ‘On.’
The system is operational.
•
Start the loads.
8.2. Shutdown procedure.
•
Stop the loads.
•
Set general two-pole output switch
(Q2)
to ‘Off.’
•
The output disconnector of the system
IS NOT OF
THE ON LOAD-DISCONNECTOR TYPE.
•
Set general three-pole input switch
(Q1)
to ‘Off.’
•
In systems with accumulators in a separate cabinet, set two-
pole battery disconnector with fuses
(Q8)
to ‘Off.’
•
Set two-pole battery disconnector with fuses
(Q3)
to ‘Off.’
•
The battery protection of the system and/or of the ac-
cumulator cabinets
IS NOT OF THE ON LOAD-DIS-
CONNECTOR TYPE.
Do not operate on it when the system
is supplying output voltage from the batteries.
The system is completely out of service.
