User manual V.3.1.0 3
1INTRODUCTION
Congratulations! You are about to install and use a device from the Xtender range. You have
chosen a high-tech device that will play a central role in energy saving for your electrical
installation. The Xtender has been designed to work as an inverter / charger with advanced
functions, which can be used in a completely modular way and guarantee the faultless functioning
of your energy system.
When the Xtender is connected to a generator or network, the latter directly supplies the
consumers, and the Xtender works like a battery charger and backup device if necessary. The
powerful battery charger has an exceptional high efficiency and power factor correction (PFC)
close to 1. It guarantees excellent battery charging in all situations. The charge profile is freely
configurable according to the type of battery used or the method of usage. The charge voltage is
corrected depending on the temperature, thanks to the optional external sensor. The power of the
charger is modulated in real time dependent according to the demand of the equipment
connected at the Xtender output and the power of the energy source (network or generator). It
can even temporarily backup the source if the consumer demand exceeds the source capacity.
The Xtender continuously monitors the source to which it is connected (network or generator) and
disconnects itself immediately if the source is missing, disturbed or does not correspond to the
quality criteria (voltage, frequency, etc.). It will then function in independent mode, thanks to the
integrated inverter. This inverter, which has an extremely robust design, benefits from STUDER
Innotec’s many years of experience and expertise in this area. It could supply any type of load
without faults, enjoying reserves of additional power that is unmatched on the market. All your
equipment will be perfectly provided with energy and protected from power outages in systems
where energy supply is unpredictable (unreliable network) or voluntarily limited or interrupted, such
as hybrid installations on remote sites or mobile installations.
The parallel and/or three-phase network operation of the Xtender offers modularity and flexibility
and enables optimum adaptation of your system to your energy requirements.
The RCC-02/03 control, display and programming centre (optional) enables optimum configuration
of the system and guarantees the operator continuous control for all important configurations in
the installation.
In order to guarantee perfect commissioning and functioning of your installation, please read this
manual carefully. It contains all the necessary information relating to the functioning of the inverters
/ chargers in the Xtender series. The setting up of such a system requires special expertise and may
only be carried out by qualified personnel familiar with the applicable local regulations.

personnel. Do not attempt to carry out ongoing maintenance of this product yourself.
The Xtender or the generator connected to it may start up automatically under certain
predetermined conditions.
When working on the electrical installation, it is important to be certain that the source of
DC voltage coming from the battery as well as the source of AC voltage coming from a
generator or network have been disconnected from the electrical installation.
Even when the Xtender has been disconnected from the supply sources (AC and DC), a
dangerous voltage may remain at the outputs. To eliminate this risk you must switch the
Xtender OFF using the ON/OFF button (1). After 10 seconds the electronics is discharged
and intervention may take place without any danger.
All elements connected to the Xtender must comply with the applicable laws and regulations.
Persons not holding written authorisation from Studer Innotec are not permitted to proceed with
any change, modification or repairs that may be required. Only original parts may be used for

STUDER Innotec
Xtender
6 V.3.1.0 User manual
In the event of use in motorised vehicles, the Xtender must be protected from dust, splash water
and any other humid condition. It must also be protected from vibration by installing absorbent
parts.
2.4.2 Precautions for using the batteries
Lead-acid or gel batteries produce a highly explosive gas with normal use. No source of sparks or
fire should be present in the immediate vicinity of the batteries. The batteries must be kept in a well-
ventilated place and be installed in such a way as to avoid accidental short-circuits when
connecting.
Never try to charge frozen batteries.
When working with the batteries, a second person must be present in order to lend assistance in the
event of problems.
Sufficient fresh water and soap must be kept to hand to allow adequate and immediate washing
of the skin or eyes affected by accidental contact with the acid.
In the event of accidental contact of the eyes with acid, they must be washed carefully with cold
water for 15 minutes. Then immediately consult a doctor.
Battery acid can be neutralised with baking soda. A sufficient quantity of baking soda must be
available for this purpose.
Particular care is required when working close to the batteries with metal tools. Tools such as
screwdrivers, open-ended spanners, etc. may cause short-circuits. Consequently occurring sparks
may cause the battery to explode.
When working with the batteries, all metal jewellery such as rings, bracelet watches, earrings, etc.,
must be taken off. The current output by the batteries during a short-circuit is sufficiently powerful to
melt the metal and cause severe burns.
In all cases, the instructions of the battery manufacturer must be followed carefully.
3ASSEMBLY AND INSTALLATION
3.1 HANDLING AND MOVING
The weight of the Xtender is between 35 and 50kg depending upon the model. Use an appropriate
lifting method as well as help from a third party when installing the equipment.
3.2 STORAGE
The equipment must be stored in a dry environment at an ambient temperature of between
-20°C and 60°C. It stays in the location where it is to be used a minimum of 24 hours before being
set up.
3.3 UNPACKING
When unpacking, check that the equipment has not been damaged during transportation and
that all accessories listed below are present. Any fault must be indicated immediately to the
product distributor or the contact given at the back of this manual.

Protected from water and dust and in a place with no condensation.

STUDER Innotec
Xtender
User manual V.3.1.0 7
It must not be situated directly above the battery or in a cabinet with it.
No easily inflammable material should be placed directly underneath or close to the Xtender.
Ventilation apertures must always remain clear and be at least 15cm from any obstacle that may
affect the ventilation of the equipment according to fig. 2b.
In mobile applications it is important to select an installation site that ensures as low a vibration level
as possible.
3.5 FASTENING
The Xtender is a heavy unit and must be mounted to a wall designed to bear such a
load. A simple wooden panel is insufficient.
The Xtender must be installed vertically with sufficient space around it to guarantee adequate
ventilation of the device (see figs. 2a and 2b).
3.5.1 Fastening XTH model
Firstly fix the mounting bracket (18)) supplied with the device using 2 Ø < 6-8 mm >screws**.
Then hang the Xtender on the bracket. Fasten the unit permanently using 2 Ø <6-8 mm> screws**
on to the two notches located at the underside of the case.
3.5.2 Fastening XTM model
Screw on a solid wall (concrete or metallic wall) an M8 screw without washer up to a distance of
1.6 mm of the wall.
Hang the apparatus by having care to release beforehand the trap door of access (17) by
inserting it inside the apparatus using a screwdriver, if you estimate that a complete tightening of
this point of fixing is necessary. In theory complete tightening is necessary only in the mobile
installations.
Dismount the lower plastic cap of the apparatus giving access to the compartment of wiring.
Carefully fix the apparatus with two screws (Ø 6-8 mm) in the two clamp holes (16) inside the
compartment of wiring.
If the Xtender is installed in a closed cabinet this must have sufficient ventilation to guarantee an
ambient temperature that conforms to the operation of the Xtender.
**: These items are not delivered with the device.
It is imperative to ensure complete and safe fastening of the device. A device that is
simply hung may detach and cause severe damage.
In motor vehicles or when the support may be subject to strong vibrations, the Xtender must be
mounted on anti-vibration supports.
3.6 CONNECTIONS
3.6.1 General recommendations
The Xtender falls within protection class I (has a PE connection terminal). It is vital that a protective
earth is connected to the AC IN and/or AC OUT PE terminals. An additional protective earth is
located between the two fastening screws at the bottom of the unit (fig. 2b-(17)).

STUDER Innotec

In all cases, the PE conductor for the equipment must at least be connected to the PE
for all equipment in protection class I upstream and downstream of the Xtender
(equipotential bonding). It is mandatory that the legislation in force for the application
concerned be adhered to.
Tighten of the input (13) and output (14) terminals by means of a no. 3 screwdriver and those for
the “REMOTE ON/OFF” (7) and “AUX.CONTAC” (8) by means of a no. 1 screwdriver.
The cable sections of these terminals must conform to local regulations.
All connection cables as well as the battery cables must be mounted using cable restraints in order
to avoid any traction on the connection.
Battery cables must also be as short as possible and the section must conform with the applicable
regulations and standards. Sufficiently tighten the clamps on the “battery” inputs (fig. 4a (11) and
(12)).

4.1 CHOICE OF SYSTEM
The Xtender may be used in different system types, each of which must meet the standards and
particular requirements associated with the application or site of installation. Only an appropriately
qualified installer can advise you effectively on the applicable standards with regard to the various
systems and the country concerned.
Examples of cabling are presented in appendix I of this manual, fig. 5 and following. Please
carefully read the notes associated with these examples in the tables on p. 33 and following.
4.1.1 Hybrid type stand-alone systems
The Xtender can be used as a primary supply system for grid-remote sites where a renewable
energy source (solar or hydraulic) is generally available and a generator is used as backup. In this
case, batteries are generally recharged by a supply source such as solar modules, wind power or
small hydropower systems. These supply sources must have their own voltage and/or current
regulation system and are connected directly to the battery. (Example, fig. 11)
When the energy supply is insufficient, a generator is used as a back-up energy source. This allows
the batteries to be recharged and direct supply to consumers via the Xtender transfer relay.
4.1.2 Grid-connected emergency systems
The Xtender can be used as an emergency system, also known as an uninterruptible power supply
(UPS) – enabling a reliable supply to a site connected to an unreliable network. In the event of an
interruption to the energy supply from the public network, the Xtender, connected to a battery,
substitutes the faulty source and enables a support supply to the users connected downstream.
These will be supplied as long as the energy stored in the battery allows. The battery will quickly be
recharged at the next reconnection to the public grid.
Various application examples are described in figs. 8a – 8c in appendix I.
The use of the Xtender as a UPS must be carried out by qualified personnel who have
been checked by the responsible local authorities. The diagrams in the appendix are
given for information and as a supplement. The applicable local standards and
regulations must be adhered to.
4.1.3 Integrated mobile systems
These systems are meant to be temporarily connected to the grid and ensure the supply of the
mobile system when this is disconnected from the grid. The main applications are for boats, service
vehicles and leisure vehicles. In these cases, two separate AC inputs are often required, one
connected to the grid and the other connected to an on-board generator. Switching between
two sources must be carried out using an automatic or manual reversing switch, conforming to the
applicable local regulations. The Xtender has a single AC input.
Various application examples are described in figs. 10a – 10b – 10c).
4.1.4 Multi-unit systems
Whatever system is selected, it is possible to realise systems composed of several units of the same
type and the same power output. Up to three Xtenders in parallel or three extenders forming a
three-phase grid or three times two or three Xtenders in parallel forming a three-phase / parallel
grid, may be thus combined.
4.2 EARTHING SYSTEM
The Xtender is a protection class I unit, which is intended for cabling in a grid type TT, TN-S or TNC-S.
The earthing of the neutral conductor (E) is carried out at a sole installation point, upstream of the
RCD circuit breaker (D).

STUDER Innotec
Xtender
12 V.3.1.0 User manual
The Xtender can be operated with any earthing system. In all cases it is imperative that the
protective earth be connected in compliance with the applicable standards and regulations. The
information, notes, recommendations and diagram mentioned in this manual are subject to local
installation regulations in every case. The installer is responsible for the conformity of the installation
with the applicable local standards.
4.2.1 Mobile installation or installation connected to the grid via plug
connector
When the input of the device is connected directly to the grid via a plug, the length of the cable
must not exceed 2 m and the plug must remain accessible.
In the absence of voltage at the input, the neutral and live are interrupted, thereby guaranteeing
complete isolation and protection of the cabling upstream of the Xtender.
The earthing system downstream of the Xtender is determined by the upstream earthing system
when the grid is present. In the absence of the grid, the earthing system downstream of the inverter
is in isolated mode. The safety of the installation is guaranteed by the equipotential bonding.
The connection (link) between the neutrals (C) upstream and downstream of the
Xtender is not permitted in this configuration.
This connection type guarantees the optimal continuity for supplying the Xtender loads. The first
isolation fault will not lead to an interruption in the supply.
If the installation requires the use of a permanent isolation controller this would have to be de-
activated when the TT network is present at the Xtender input.
All sockets and protection class I devices connected downstream of the Xtender must
be properly connected to the earth (earthed socket). The cabling rules above remain
valid, including in installations, in all cases where the Xtender input is connected to the
grid via a plug connector.
4.2.2 Stationary installation
The installation may be equivalent to a mobile installation (with interrupted neutral).
In a fixed installation where the neutral is connected to the earth at a single installation point
upstream of the Xtender, it is permissible to carry out a connection of the neutrals in order to
preserve an unchanged earthing system downstream, independent of the operating mode of the
Xtender. This choice has the advantage of keeping the protection devices downstream of the
Xtender. This connection can be executed according to the examples in appendix 1, or carried
out by modifying the configuration {1486}
In this case the appearance of the first fault will lead to the installation stopping or the
disconnection of the protection devices upstream and/or downstream of the Xtender.
Safety is guaranteed by the equipotential bonding and by any RCD circuit-breakers placed
downstream.
This connection (C) is not permitted if a socket is installed upstream of the Xtender.
4.2.3 Installation with automatic PE-neutral switching
In certain applications, it is desirable to keep the neutral upstream and downstream of the Xtender
separated (C) while re-establishing the earthing system (TN-S, TT or TNC-S) in the absence of voltage
at the input. This can be programmed by the configuration {1485} via the RCC-02/03 remote
control. This modification must be carried out possessing technical knowledge, at the responsibility
of the installer and in conformity with the applicable regulations and standards.
This allows adherence to the requirements for an earth-neutral connection at the source.

4.3 RECOMMENDATIONS FOR DIMENSIONING THE SYSTEM
4.3.1 Dimensioning the battery
The battery capacity is dimensioned according to the requirements of the user – that is 5 to 10
times its average daily consumption. The discharge depth of the battery will therefore be limited
and the service life of the battery will be extended.
On the other hand, the Xtender must have a battery capacity that is large enough to be able to
take full advantage of the performance of the equipment. The minimum capacity of the batteries
(expressed in Ah) is generally dimensioned in the following way: five times the rated power output
of the Xtender / the battery voltage. For example, the model XTH 8048 must have a battery of a
minimum capacity of 7000*5/48=730 Ah (C 10). Because of the inverter’s extreme overload
capacity, it is often recommended that this value be rounded up. An under-dimensioned battery
may lead to an accidental and undesired stopping of the Xtender in the event of high instances of
use. This stoppage will be due to a voltage that is insufficient on the battery, subject to a strong
discharge current.
The battery will be selected with regard to the greatest value resulting from the calculations set out
above.
The battery capacity determines the adjustment of the configuration {1137} “battery charge
current”. A value between 0.1 and 0.2 x C batt. [Ah] (C10) enables an optimum charge to be
guaranteed.
The method proposed below is strictly indicative and in no way constitutes a guarantee
of perfect dimensioning. The installer is solely responsible for good dimensioning and
installation
4.3.2 Dimensioning the inverter
The inverter is dimensioned in such a way that the rated power output covers the power of all the
consumers which will be used at the same time. A dimensioning margin of 20 to 30% is
recommended to guarantee that the Xtender will work well in an ambient temperature of more
than 25 °C.
4.3.3 Dimensioning the generator
The power output of the generator must be the same or more than the average daily power.
Optimally, it should be two or three times this power. Thanks to the smart boost function it is not
necessary to over-dimension the generator. Indeed, the loads those are temporarily higher than
the power of the generator will be supplied by the inverter. Ideally it should not have a power
output by phase that is less than half of the power of the Xtender(s) present at this phase.
The power available downstream of the inverter when the generator is working is the
same as the sum of the two powers.
4.3.4 Dimensioning the renewable energy sources
In a hybrid system, the alternative energy sources such as the solar generator, wind power and
small hydropower should, in principle, be dimensioned in such a way as to be able to cover the
average daily consumption.

4.4 WIRING DIAGRAMS
4.5 CONNECTING THE BATTERY
Lead batteries are usually available in 2 V, 6 V or 12 V block types. In the majority of cases, in order
to obtain an operating voltage that is correct for Xtender usage, several batteries must be
connected in series or in parallel depending on the circumstances.
The various cabling options are presented in figures 5a-5b (12 V), 5c-5e (24 V) and 6a to 6d (48 V) in
appendix I of this manual.
4.5.1 Battery cable cross-section and DC protective devices
The battery cables must also be as short as possible.
It is always preferable to keep the cable at the negative pole of the battery as short as possible.
In order to avoid any further loss and protection redundancy, the XTH does not have an internal
fuse.
A protective device (f) must be installed as close as possible to the battery and sized according to
the below table.
The recommended cable cross-sections are valid
for lengths less than 3 m. beyond this length it is
strongly recommended oversize the battery
cables.
The diagrams shown in the appendix of this document are subsidiary. The applicable
local installation regulations and standards must be adhered to.
The elements referred to with an uppercase letter denote the alternate current (AC)
part.
The elements referred to with a lowercase letter denote the direct current (DC) part.
In multi-unit systems, all Xtenders from the same system must be connected according to
the same battery bank.
The battery cables must be protected by one of the following measures in all cases:
- protection device (fuse) at each pole
- protection device (fuse) on the pole not connected to the earth
