Activate the minimum charge you wish to detect.
Turn the screw slowly anti-clockwise
until
the inverter activates. (green LED illuminated).
Check that the inverter goes back to standby
mode a couple of seconds after deactivation of
all charges.
Warning
: In maximum anti-clockwise position
the inverter continues to work even if there is no
load
.
Control
The tension of the batteries is submitted to
control. During their use, the tension must be
between the following ranges :
11.4 V and 16 V in the 12 Volt models,
22.8 V and 32 V in the 24 Volt models,
45.6 V and 61 V in the 48 Volt models.
Outside these ranges the inverter is
automatically disconnected.
These values correspond to a no load situation
and they are automatically adjusted according to
the current of the battery.
The internal temperature and the maximum
power are also submitted to control.
In the case of prolonged overload or deficient
ventilation it is not possible to restart the inverter
until it has cooled down.
Indicators
Green Run - LED (3)
Illuminated: the inverter is connected. A 230 V
tension is present in the outlet.
Blinking : (only SI version) The inverter is in
“ Autom. ” mode and no voltage is detected by
the standby system.
A 230 V tension is intermittently present!
Red Fault - LED (2)
The inverter is stopped :
The tension of the battery is not correct
After an overload, overheating or short circuit
To restart the inverter after a failure, put the
switch (4) in “ OFF ” position for 10 seconds,
then connect again
.
Safety
The inverter is internally protected against
overloads and short circuits. Should this
protection fail, the inverter is equipped with a
fuse (fire protection). If the fuse is broken,
qualified technicians should control the
installation and change the fuse.
Internal fuse
Fuse
Inverter HPSI (CF8 fuse links)
300 A
2212 – 4424
250A 5048
The use of higher fuse value will not improve the
performance of the inverter and will degrade
safety protection !
Alarm contact
A contact with no potential (0,5A - 60V) is
available (12). It warns the user (alarm or control
system) when the inverter has been stopped
due to a failure or is out of use. It is off when the
inverter is working.
Maintenance
The SI inverters do not need any special
maintenance. The casing may be cleaned with a
damp cloth (not wet).
In the case of malfunction, the inverter should
be sent to the salesperson for control.
Legislation
In all cases the assembly and installation must
be done by qualified technicians, observing the
national requirements and rules stipulated. You
will find complete information about this in the
relevant institutions.
Limitation of liability
STUDER INNOTEC cannot control the
installation, use and maintenance of the inverter.
Thus, we are not responsible for damages,
costs or losses resulting from an installation
which is not in accordance with the regulations
or inappropriate use or maintenance.
The customer is always responsible for the use
