Introduction
The HPSI sinewave inverters have been
designed to meet industrial and domestic needs.
They satisfy the highest demands of comfort,
safety and reliability.
Any device designed for the public electrical
network of 230V / 50 Hz can be connected to
them.
The HPSI inverters are the perfect solution as
sources of tension in any place where the public
network is not available.
Read the connection instructions thoroughly and
give them to the technician who is to install the
inverter so as to prevent any malfunction. Thus
you will have a modern and reliable installation
which meets requirements.
Should you have any doubt or question, do not
hesitate to contact your specialist salesperson
who will give you the best advice.
Note
A deficient assembly could damage the device,
cause function failures or potential damage to
the users.
The working device generates a high tension
which might be fatal in case of contact. So, any
manipulation of the inverter must be carried out
with utmost care. The following points must be
strictly observed :
The installation of the "HPSI" can only be
performed by a qualified technician.
In case of malfunction, only a technician
specially designated and trained by STUDER
INNOTEC is allowed to repair the device.
Warning :
Opening the inverters or using them
incorrectly will result in the immediate
loss of the warranty.
No current or tension generating devices (public
network, generator, ...) may be connected to
the output of the inverter because this could
result in its destruction.
As for the usage of batteries, follow the
manufacturer’s instructions.
Important :
After disconnecting the battery, the output
tension (230V) may still remain for 30
seconds.
The ventilation of the device should never be
obstructed. Should the device be installed in an
enclosed structure, make sure that ventilation is
possible and adequate.
The installation and assembly of the device
must follow the rules stipulated.
This document is an essential part of the
inverter and must always be carried with it and
be at the disposition of anyone working on the
installation.
Applications and Performance
As well as its modern design and its technical
characteristics, the HPSI inverter is also easy
and economical to use in almost all applications.
All devices working within the public electrical
network (230V - 50Hz) may be used with the
inverter (up to its nominal power).
The inverter generates a perfectly sinusoid
output tension, precisely adjusted by a high
technology regulation system.
Thus, the output tension is totally independent of
the charge and the fluctuation of tension in the
battery.
All inverters in the HPSI series are protected
against overloading and short circuits.
Due to obvious safety reasons, the inverter is
not automatically reactivated after a failure
(overload, short circuit,…).
Assembly
Location
HPSI could be used as a desk-top apparatus or
could be rack mounted.
If the inverter is rack mounted, the cabinet
should be correctly ventilated in a way to insure
cold air at input of the fan.
Keep a distance of at least 3U (~15 cm)
between each units.

STUDER INNOTEC
Users’ and Installers’ Handbook HPSI V2.0 E page4
The place where the inverter is to be mounted
should meet the following requirements :
•Out of reach of non authorised persons.
•In a dry place with no condensation.
•No inflammable material in the same room.
•Not directly on top of the batteries.
•Adequate ventilation. Keep min. 10 cm
distance to other object
Air-flow path
Connection
Check the switch (4) is in “ OFF ” position.
First connect the 230V outlet (6) to the user
device, so as to prevent any possible accidental
contact.
Check the tension and polarity of the
battery !
The tension of the battery should coincide with
that mentioned in the technical characteristics of
the inverter.
Battery connection :
This connection should done be very
carefully observing the polarity in order not
to damage the device.
Check that the connections are fixed correctly.
Use
After connecting the inverter, make sure the
user devices are correctly plugged in and that
there is no possible contact between the “ Line
OUT ” (6) and a person.
The working device generates high tensions
which could be fatal !
The inverter can be activated by moving the
switch to the “ Auto ” position. The “ on ”
indicator -green LED -(3) is illuminated.
If no user device is connected, the LED blinks
after some seconds, which indicates that the
“ standby ” mode has started. If a user device is
plugged in, the green LED remains illuminated,
indicating the uninterrupted presence of 230V in
the outlet. If you wish to deactivate the standby
mode, put the switch in “ Lock ” position. The
inverter will be then working continuously.
Warning :
With the “lock” mode, the no load
consumption of the inverter is 15 to 20
times greater !
Remote control
The inverter can be controlled remotely with a
switch (bi-stable) connected to the (5)
connector on the Back side of the device.
The main switch (4) has priority over the
working mode of the device. If the remote
switch is close, the inverter is out of use.
Adjustments
Standby Level (1)
The activation of the inverter, when working in
automatic mode, is dictated by the detection of a
load. With this function, it is possible to adjust
the minimum load detected between 0,3 and 20
Watts. This level is factory adjusted to 2
watts and so no further adjustment will
probably be needed.
Adjustment procedure
Make sure that no device is connected.
Check for the presence of hidden users such as
television, fax, video, … which often have a
standby mode and remain working even after
being turned off !
Put the switch in “ Autom. ” position.
Introduce a screw driver N°2 in the adjustment
knob (1) provided.
Turn clockwise until tight
Wait until the green LED blinks.

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.

If a ground fault detector (FI) is used, this short should be done.
•There is capacitive splitter on both output and input of the inverter. This mean
that half the output voltage is present between any output wire (blue or Braun)
and the earth wire (Yellow/green).
•If a “real neutral” is needed; you have to make a short between the blue wire and
the yellow/green wire. This point can also be tied to ground if there is an existing
ground.
•Every ground point of appliances or plug should be tied together.
•One side or the other of plus or minus battery input could also be tied to ground
if needed.
•A “real neutral is an absolute need if there is a FI ground fault detector used as
safety device.
In any case, he installation of an inverter should follow the specific rules in force in
the country of installation.
STUDER SOLARTECHNIK do nott assume any responsibility for damages, costs or losses arising
from using STUDER inverters, or in any way resulting from an installation which is not in
accordance with the in force regulations or for an inappropriate use of the inverter.
