OVERVIEW
The new three-phase/single-phase TRIPOWER X31 HE 10 – 15 – 20 kVA series (VFI-SS-111 type) have been designed using
the latest technology available today so as to guarantee users maximum performance. The use of the new control PCBs based
on multiprocessor architecture (DSP + P inside) together with high frequency IGBT technology offers excellent performance both
in the input stage (absorbed current harmonic distortion ≤ 3%) and in output (output voltage distortion ≤ 1%).
Thanks to these and many other features plus the easy-to-use design, this new series represents a new reference standard for
single-phase output TRIPOWER X31 HE systems.
Depending on user requirements, there are two different versions available:
Optional Small Size
The Optional Small Size version stands out by its
compact size and new, modern design. These features
make it suitable for any environment.
Standard
The Standard version, offers longer autonomy than
the Optional Small Size version, thanks to the
possibility to double the number of batteries inside the
cabinet.

BATTERY BOX (OPTIONAL)
THE BATTERY BOX IS AN OPTIONAL ACCESSORY. THIS TRIPOWER X31 HE RANGE HAS BATTERY BOX VERSIONS
OF THE SAME SIZE AND MATCHING STYLE.
The Battery Box contains batteries that increase the operating time of the UPS during prolonged black-outs. The number of
batteries contained in it will vary according to the type of TRIPOWER X31 HE to which the Battery Box is to be installed. The
utmost attention must be paid to ensure that the battery voltage of the Battery Box corresponds to that supported by the UPS.
Optional Small Size Standard
Additional Battery Boxes may be connected in a chain to obtain the desired autonomy time during a power failure.
This series of Battery Box contains two separate strings of batteries, one with a positive voltage and the other with a negative
voltage with respect to the neutral terminal (N).

SEPARATE BYPASS INPUT (OPTIONAL)
THE DI (OPTIONAL) VERSION OF THE TRIPOWER X31 HE SERIES HAS SEPARATE BYPASS AND INPUT LINES.
The TRIPOWER X31 HE series with separate Bypass ensures a separate connection between the input and bypass lines.
The TRIPOWER X31 HE output is synchronised with the bypass line so as to safeguard against incorrect voltage changeovers in
the alternate phases, in the event of automatic bypass or closing of the maintenance switch (SWMB).
INTERNAL TRANSFORMER
THE OT (OPTIONAL) VERSION OF THE TRIPOWER X31 HE SERIES DIFFERS FROM THE OPTIONAL SMALL SIZE
VERSION IN THAT IT USES AN ISOLATION TRANSFORMER INSTEAD OF THE BATTERIES.
This series of TRIPOWER X31 HE uses an isolation transformer connected to the UPS output terminals.
NOTE: A separate bypass line is supplied on this UPS version.
The transformer is connected to the TRIPOWER X31 HE output terminals, so the values displayed are those of the
quantities measured upstream of the transformer.
The presence of the transformer inside the UPS modifies the system neutral arrangements.
The installation of a remote maintenance bypass parallel to the UPS is incompatible with inclusion of the
transformer. In any event, if the remote maintenance bypass is inserted, make sure, at the time the remote bypass
switch is closed, that the UPS is isolated from the system by opening the input and/or output switches.
ADDITIONAL INTERNAL BATTERY CHARGERS
THE AC (OPTIONAL) VERSION OF THE TRIPOWER X31 HE SERIES DIFFERS FROM THE OPTIONAL SMALL SIZE
VERSION IN THAT SOME ADDITIONAL BATTERY CHARGERS ARE USED INSTEAD OF THE BATTERIES.
This series of TRIPOWER X31 HE must be used together with an external Battery Box and is suitable for applications requiring
long back-up times.
NOTE: A separate bypass line is supplied on this UPS version.
The additional internal battery charger cards are powered directly on mains power and have pseudo-sinusoidal wave form
absorption.
If the input switch is closed but the I/O switch is open (UPS switched off) the battery chargers operate independently.
Open the input switch (SWIN) to totally shutdown the UPS and the additional battery chargers.

** The following formula can be used to calculate the fan capacity: Q [mc/h] = 3.1 x Pdiss [kcal/h] / (ta - te) [°C]
Pdiss is the dissipated power of all the installed apparatus at the installation premises expressed in kcal/h.
ta= environmental temperature, te= external temperature. To account for leaks, increase the value obtained by 10%.
The table shows an example of the fan capacity with (ta - te)=5°C and with nominal resistive load (pf=0.8).
(N.B.: The formula applies if ta>te; otherwise an air conditioner should be installed).
*** The dispersion current of the load is added to the dispersion current of the UPS on the earth protection conductor.

ELECTROMAGNETIC COMPATIBILITY
This TRIPOWER X31 HE product conforms to the current electromagnetic compatibility (EMC) regulations (C2 class). It may
cause radio interference in the home environment. The user may have to adopt supplementary measures.
This product is for professional use in industrial and commercial environments. Connections to USB and RS232 connectors must
be made with the cables provided, or at least with shielded cables less than 3 metres long.
INSTALLATION ENVIRONMENT
When choosing the site in which to install the TRIPOWER X31 HE and the Battery Box, the following points should be taken into
consideration:
 Avoid dusty environments
 Check that the floor is level and capable of withstanding the weight of the TRIPOWER X31 HE and the Battery Box
 Avoid cramped environments that could impede the normal maintenance activities
 The relative humidity should not exceed 90%, non-condensing
 Check that the ambient temperature, with the TRIPOWER X31 HE running, remains between 0 and 40°C
The UPS may be operated with an ambient temperature of between 0 and 40°C. The recommended
working temperature for the UPS and the batteries is between 20 and 25°C. In fact, if the battery has an
average life of 5 years with a working temperature of 20°C, the life is halved if the working temperature is
increased to 30°C.
 Avoid installing the equipment in places exposed to the direct sunlight or hot air
To keep the temperature of the installation room within the range indicated above, there must be a system for eliminating the
dissipated heat (the TRIPOWER X31 HE kW / kcal/h / B.T.U./h dissipation values are shown in the table on the previous page).
The methods that may be used are:
 Natural ventilation
 Forced ventilation, recommended if the outside temperature is less (e.g. 20°C) than the temperature at which the
TRIPOWER X31 HE or Battery Box is to be operated (e.g. 25°C)
 Air-conditioning system, recommended if the outside temperature is higher (e.g. 30°C) than the temperature at which the
TRIPOWER X31 HE or Battery Box is to be operated (e.g. 25°C)

INSTALLING THE TRIPOWER X31 HE AND THE BATTERY BOX
When installing the equipment, the following points should be considered:
 The wheels are to be used exclusively for fine positioning, and thus for small distances only.
 The plastic parts and the door are not to be used for gripping or pushing the TRIPOWER X31 HE.
 Sufficient space should be left in front of the equipment for it to be turned on/off and maintenance operations to be
performed on it (  1.5 mt )
 The rear part of the TRIPOWER X31 HE should be set at least 30 cm from the wall, to enable the air blown by the
ventilation fans to flow away correctly
 No objects should be left on its top surface
Having set the equipment in position, secure it by engaging the brake rod (see "Front Views of the TRIPOWER X31 HE" point 8)
situated below the connecting terminals.
(Standard version only): In seismic areas or for mobile systems, the brackets used to fasten the unit to the pallet (ramps) can
be reused to anchor the UPS to the floor (see the figure below). In normal conditions, the brackets are not necessary.

ELECTRICAL CONNECTIONS
WARNING: a 4-wire three-phase distribution system is required for the three-phase input connection. The
UPS must be connected to a power supply line made up of 3 phases + neutral + PE (protective earth) of TT, TN or
IT type. Therefore, the phase rotation must be respected.
Optional TRANSFORMER BOXES to convert the distribution systems from 3 wires to 4 wires are available.
WIRING DIAGRAMS FOR CONNECTING TO THE ELECTRICAL SYSTEM
NOTE: for the following diagrams, in cases of single-phase connections on the input line, instead of 3P=N, please read P+N.

Separate bypass:
if the separate bypass option is present, protective devices must be present on both the main power supply line and the bypass
line.
Note: the neutral of the input line and that of the bypass are commoned inside the equipment, so they must refer to the same
potential. If the two power supplies were different, an isolation transformer would have to be used on one of the inputs.

and a battery charger charged with 4A.
** In versions with additional internal battery chargers (optional), the maximum input current on lines L2 and L3 must be increased
by 7A.
SHORT CIRCUIT
If a failure occurs on the load, the TRIPOWER X31 HE protects itself by limiting the value and duration of the current output (short-
circuit current). These values also depend on the operating status of the TRIPOWER X31 HE at the time of the failure; there are
two different cases:
 TRIPOWER X31 HE in NORMAL OPERATION: the load is switched instantaneously to the bypass line (I2t=11250A2s):
the input line is connected to the output without any internal protection (blocked after t>0.5s)
 TRIPOWER X31 HE in BATTERY OPERATION: the UPS protects itself by providing a current equivalent to about 1.5
times the rated current for 0.5s and turns itself off after this time has elapsed
BACKFEED
The TRIPOWER X31 HE has internal protection against backfeed through metal separating devices.
There is an output on the relay board (optional) for activating a releasing device to be installed upstream from the TRIPOWER
X31 HE.
The TRIPOWER X31 HE has an internal device (redundant bypass power supply) which, when a failure occurs on
the machine, activates the bypass automatically, thus keeping the load powered without any internal protection and
without any limitation to the power supplied to the load.
Under these emergency conditions, any disturbance present on the input line will affect the load.
See also the “USE” section of the “Redundant Auxiliary Power Supply for Automatic Bypass” paragraph.
