1. Preliminary operations
1.1 Removing the packaging and positioning the device
On delivery, the packaging must be inspected to ensure that it is whole and that it has not been crushed or dented.
Check in particular that neither of the two impact resistant devices on the packaging is red; if one of them is red,
follow the instructions on the packaging.
The essential details of the device are provided on the shipping document. The marking, weight and dimensions of
the various items making up the packing list are shown.
Check the state of the device by means of a visual inspection of both the inside and the outside. Any dents seen
mean that it has suffered knocks during shipping, which could compromise the normal operation of the device.
1.2 Storage
In the following situations:
installation not immediately after delivery;
de-installation and storage while awaiting relocation,
place the device in covered premises that are protected from direct contact with atmospheric agents and dust. The
following environmental values are those allowed in the storage area:
Temperature: -25 ÷ + 60 °C
Relative humidity: 30 ÷ 95 % max.
For the installation of a battery cabinet, if provided with the uninterruptible power supply, follow the
instructions given in the specific manual.
The list of material provided may vary depending on the order specifications. As a general rule, the packaging should
include the following: this manual, the installation drawing, the warranty and eventual accessories.
1.3 Handling
The equipment must only be handled by adequately trained personnel. It can be unloaded from the vehicle and put
into place by lifting the box or the wooden deck to which the equipment is secured with a fork-lift truck. A transpallet
or fork-lift truck should be used for the permanent positioning of the equipment, in accordance with the instructions
provided below.
Page 7 to 54

1 Insert the forks of the fork-lift truck in the lower part of the device, from the front or back, and ensure that they
stick out about 30 cm on the other side.
If a transpallet is used, raise the device only as much as is strictly necessary.
2 Secure the device to the transpallet or fork-lift before moving it.
Risk of overturning
In order to avoid the risk of the device overturning, ensure that it is firmly secured to the transpallet or
fork- lift truck by means of appropriate ropes before moving it.
When being moved the cabinet should be handled with care; knocks or drops can damage it. Once in position,
remove the packaging carefully in order not to scratch the device.
The packaging should be removed as follows:
1. Cut the bands
2. Slide away the carton from above.
3. Remove the screws securing the cabinet to the wooden base.
4. If using a transpallet, remove the device from the pallet and set it on the floor, using the same precautions as
set out in the section on Handling.
2. Installation environment
The TRI POWER X33 HIP and the battery cabinet have been designed for indoor installation. The choice of
premises for installation should comply with the points set out below.
2.1 Ambient conditions:
ensure that the floor can support the weight of the UPS and of any battery cabinet that may be used;
avoid dusty environments;
avoid narrow environments that could hinder normal maintenance operations;
avoid placing the device in areas exposed to direct sunlight or heat;
ensure that the ambient temperature conforms to the following:
minimum operating temperature: 0 °C
maximum temperature for 8 hours a day: + 40°C
average temperature for 24 hours: + 35°C
max relative humidty: 95 % without condensation
Max installation height: 1000 m at rated power
(-1% power for every 100 m above 1000 m) max 4000 m
2.2 Dimensions of the premises
For the mechanical dimensions of the cabinets, refer to the “INSTALLATION DRAWINGS” supplied with the UPS
and with the battery cabinet, if present. These drawings provide the following data:
the position of the holes in the base to secure the device to the floor, if applicable;
the view of the floor support for the sizing of a structure to raise the cabinet, if applicable;
the position of cable entry;
the position of the fans on the top of the UPS, for the positioning of a structure to convey the warm air
discharged by the equipment outside the premises, if applicable;
the input, output and battery cables section;
the power dissipated by the equipment (kW).
Page 8 to 54

2.3 Cooling of the premises
The recommended operating temperature for the lifetime of the UPS and of the batteries is between 20 and 25°C.
The lifespan of the battery depends on the operating temperature; with an operating temperature of between 20°C
and 30°C, the lifespan of the batteries is halved. A heat dissipation system is required to keep the temperature of the
premises housing the equipment within the field 20÷25°C.
The heat dissipation needed for the correct operation of the UPS is brought
about by the air current made by the fans located inside the UPS (forced
convection) and by the air around the side panels (natural convection).
In order to ensure proper air circulation, and therefore the correct operation of
the UPS, measures must be taken during installation to avoid any obstructions
to the free circulation of air. These include the following:
ensure a distance of at least 60 centimetres from the ceiling, so as not
to hinder air extraction,
leave a free space of at least one metre at the front of the equipment
to ensure both the circulation of the air and installation and
maintenance operations;
With natural convection the thermal load is dissipated to the outside
through the walls; thus a cabinet placed against a wall or in a hollow
dissipates less heat than one located in a free environment.
The following rule must be observed:
leave at least one of the three side walls free: right, left or back.
the side strips must not be mounted for installations where cabinets are placed side by side.
2.4 Air change for battery premises
The room in which the battery box is installed must be provided ventilated so as to keep the concentration of
hydrogen generated during charging within safe limits. The room should preferably be ventilated naturally; if it cannot
be, forced ventilation may be employed. Standard EN 50272-2 regarding air exchange provides that the minimum
aperture must satisfy the following equation:
A = 28 x Q = 28 x 0.05 x n x Igas x C10 (1/10³) [cm²]
where: A = surface free of air input/output opening; Q = air flow to be exhausted [m³/h];
n = number of battery elements; C10 = battery capacity in 10 hours [Ah];
Igas = gas producing current [mA//Ah]
according to the standard:
Igas = 1 in backup charging for VRLA type batteries (*); Igas = 8 in fast charging for VRLA type batteries (*)
(*) for open vessel or nickel batteries, contact the battery manufacture for details.
example calculation
Type of battery: VRLA; Number of elements: 240 (40 mono-blocks)
Capacity: 120Ah; Igas (**): 8 (fast charging)
A = 28 x Q = 28 x 0.05 x n x Igas x C10=28 x 0.05 x 240 x 8 x 120 x 1/10³ = 322 cm2
(**) to increase the safety margin, we take the fast charging condition, well aware that the battery mostly runs in
backup charging mode. Using the backup charging value for Igas would result in a value of one eighth of the above.
The air intake/outlet must be located so as to be most favourable to circulation, e.g.:
openings on opposing walls;
with a minimum distance of 2 m if both on the same wall.

3. TRI POWER X33 HIP in single configuration
3.1 Set-up of the electrical system
3.1.1 Input
The UPS input must have a max. current protection device for the section of line coming from the distribution panel
as well as for the two inputs into the TRI POWER X33 HIP : the rectifier line and the bypass line.
The protection device should be sized according to the situation, as follows:
a) single power line
b) main power supply and separate bypass
a) Single power line
The UPS input must have a max. current

3.1.2 Selectivity
The system where the UPS is inserted must be set up in such a way that in the event of a shortcircuit on one of the
lines downstream of the UPS, the fuse on the output opens while the upstream fuse normally works. This is known
as selectivity, and ensures that the remaining feeders maintain the power supply.
In order to select the correct protection devices to be
inserted downstream of the TRI POWER X33 HIP, the
following two operating modes have to be taken into
consideration: mains power supply and battery power
supply.
With mains power supply the output fuse must be selective with the input fuse; the condition is verified for the
following values:
[kVA]
300
400
500
600
800

At least two feeders are necessary in order to use the UPS at rated load with fuses of type gG.
With battery power supply (first fault) in the event of a shortcircuit on one of the outputs (second fault) it must be
possible for the fuse to be open before the inverter shuts down.
If the shortcircuit is of the three-phase type, the inverter can supply a current for 1 second that is 1.8 times the value
of the rated current of the UPS output (with a single phase shortcircuit the current is around 3 times the value).
In the worst-case scenario, that is a three-phase shortcircuit then a smaller current, the condition occurs if:
[kVA]
300
400
500
600
800
Rated output current:
[A]
433

1.8 times the rated output current for 1 second

160
200
250
Fuse size for type aM fuse
[A]
80
100
125
160
200
At least five feeders are necessary in order to use the UPS at rated load with fuses of type gG.
To sum up, when there is a shortcircuit on the output, there are two alternatives if only the line affected by the
shortcircuit is to be isolated; let us consider the example of the 300kVA:
selectivity with both mains power supply and battery power supply;
the load has to be shared between at least five feeders, each sized at 20% of the rated power.
selectivity, with mains power supply only:
since it is considered unlikely that after a first fault a second fault will occur in the limited time of
operation from the battery, it is sufficient to share the output between two lines, each sized for 50% of
the rated power.
Page 11 to 54

3.1.3 Battery
BATTERY CABINET
For connection to the UPS, the battery cabinet must have an overcurrent protection device and a
disconnecting device which ensure the disconnection of both the polarites
The disconnector may be closed only when the UPS is started up regularly; see the section “Start-up
procedure” on page 24.
The function of the fuses is to protect the batteries and the cables from a shortcircuit between the battery cabinet and
the UPS. The following rules should be observed for their sizing:
If rapid fuses of the type gl / gG are installed: the maximum size of fuse to be used is 2 times the battery
capacity in Ah.
If ultra rapid fuses of the type aR are installed: the maximum size of fuse to be used is 2.5 times the
battery capacity in Ah.
For example: the following fuses may be used for batteries of the type 150Ah: 315A type gl/gG or 355A type aR.
For the section of the cable for the UPS to battery connection refer to the following current value:
3.1.4 Neutral conductor
Do not connect the output neutral to ground.
The use of an isolation transformer on the bypass l ine is required should it be necessary to modify the
neutral arrangements downstream of UPS.
300-400kVA
In normal operation SWBY and SWOUT switches are closed, the opening of the SWBY do not change the state of
the neutral output system
300-400kVA
The neutral state is not a function of position of the bypass line switch.

NOTE (*): place the label supplied (The following label, supplied with the UPS, must be displayed on all switching
devices located upstream in the same electrical system as the UPS):
3.1.5 Differential (RCD)
If the TRI POWER X33 HIP protection against electric shock uses differential current devices (RCD), these have to
have the following characteristics:
Sensitivity 300mA
sensitive direct current and unidirectional components (class B)
insensitive to transient current pulses
delay greater than or equal to 0.1 s.
When operating in the presence of mains supply, a differential breaker (RCD) installed on the input will intervene as
the output circuit is not isolated from the input circuit.
When operating without mains supply (from battery) the input differential breaker will intervene only if it is able to
switch as a result of leakage current without any voltage at its poles (for example a differential breaker with an
auxiliary relay is not suitable). However it is possible to install additional differential breakers on the output of the
UPS, possibly coordinated with those on the input.
Page 13 to 54

3.1.6 Backfeed protection
The TRI POWER X33 HIP is provided with a device to prevent voltage backfeed on the input line due to an internal
fault. This protection device works by switching off the inverter if the current flow is faulty, thereby causing voltage
backfeed on the bypass line during operation from the inverter. If the fault occurs when the UPS is operating from the
battery, the load will not be powered.
Should it be required to avoid the shutting down of the inverter in order to keep the load powered by the inverter
even in the event of a double fault, the system can be customized to control the opening coil of a switch located
upstream by reprogramming one of the relays on the “REMOTE COMMANDS AND ALARMS” card.
The control logic allows the function of the relay to be reconfigured, for example for the backfeed alarm, and then the
free voltage contact can be used to control the triggering of a switch located on the UPS input.
3.1.7 Emergency power off device (EPO)
The UPS is pre-set to be connected to a remote emergency power off device as laid down in standard EN 62040-1-
2. If the remote device (not supplied with the equipment) is activated, the inverter output voltage is cut.
The connection procedure is shown below.
a - EPO terminal board located on the UPS
b - EPO switch (not provided).
On the TRI POWER X33 HIP , the jumper on the EPO terminals (page 17) must be removed, and the wires from the
auxiliary contact of the button must be connected in place of the jumper.
The contact must be closed with the button in the rest position and must open when the button is pressed.

3.2 Mains, load and battery connections
The operations described in this chapter must be carried out exclusively by a specialized technician.
The first connection to be made is the earth conductor.
The TRI POWER X33 HIP MUST NOT OPERATE WITHOUT AN EARTH CONNECTION
Before making the connection, open all the switches on the device and ensure that the UPS is completely isolated
from the power sources: battery and AC power line. More specifically, check that:
the UPS input line or lines are completely isolated;
the battery cabinet disconnector / fuse (if present) is open;
all the UPS disconnectors - SWIN, SWBY, SWOUT and SWMB - are in the open position (position 0);
check with a multimeter that there are no dangerous voltages on the terminal board.
For connection of the power cables to the terminal boards, refer to the “INSTALLATION DRAWINGS”
provided with the UPS and with the battery cabinet, if present.
INPUT NEUTRAL
The power supply to the TRI POWER X33 HIP input ( bypass line) must be three-phase with neutral.
The neutral conductor is necessary only on bypass line.
Input line without neutral
The transformer must be inserted either on the mains supply line or on the bypass line (as shown in the drawings).
OPTIONAL
Page 15 to 54

Battery connections
BATTERY CABINET if present:
For connection to the UPS, the battery cabinet must have an overcurrent protection device and a
disconnecting device. This disconnector must be closed only when the UPS is started up regularly. During
connection to the UPS the disconnector must stay in the open position.
CABINET DISCONNECTOR
For systems with more battery cabinets, use a Battery switch cabinet where the cables can be parallel-
connected (refer to the marketing department). For the sizing of the cables and connection procedures,
refer to the “INSTALLATION DRAWING” attached to the battery cabinet.

Bypass / fault, the contact changes position when the UPS switches the
load onto the bypass line either during normal operation (e.g. due to
overload) or as a result of a fault in the inverter stage;
Battery discharging, the contact changes position when the load is
powered from the battery due to a mains power failure;
End of battery discharge, the contact changes position when, during a
mains outage, the remaining time for battery discharge has reached the
minimum value defined. Once this time has passed, the load will remain
unpowered (the factory- set end of discharge pre-alarm value is 5
minutes);
IN 1
Inverter OFF. Connect pin 11 to pin 12 (for at least 2 seconds).
In “NORMAL OPERATION”,
if the INVERTER OFF command is received, the UPS switches the
power supply of the load onto the bypass line (load is not protected
should there be a mains outage).
In “EMERGENCY OPERATION”,
if the STOP INVERTER command is received, the UPS shuts down
(load is not powered).
With the jumper present, the UPS remains switched on the bypass
line when the mains power supply is restored.
With no jumper present, the UPS will restart in NORMAL
OPERATION.
3.3 Connection of signals and remote commands
To the position of the signal and remote connection, refer to the “INSTALLATION DRAWINGS” supplied with the
UPS.
3.3.1 EPO connector (emergency power off control)
If the jumper on the connector is opened, the voltage on the UPS output
will be cut.
The UPS is factory-fitted with the EPO terminals shortcircuited. If this
input is used, the UPS can be shut down in a hazardous situation from a
remote position simply by pressing a button.
If only the power supply is removed, for example by opening the switch of
the power supply panel, the UPS will keep the load powered using the
energy in the batteries
3.3.2 REMOTE COMMANDS AND ALARMS
The card is equipped with a terminal board with 12 positions which has the following:
POWER SUPPLY 1 power supply 12Vdc 80mA(max.) [pins 10 and 11];
ALARMS 3 potential-free change-over contacts for alarms;
COMMAND 1 command programmable from the panel [pins 11 and 12];
The functions of the three contacts and the command may be reprogrammed via the display panel. The ALARMS
and the COMMAND are factory-set in the following way:

The position of the contacts shown is without the alarm present. The contacts can take a max. current of 1A with
42Vac. Or 60Vdc.
Please refer to APPENDIX A for the list of alarms and commands that can be programmed. The change
of function may be made by the technical support personnel.
3.3.3 RS232
2 DB9 connectors are available for RS232 connection. The factory-set
transmission protocol is the following:
9600 baud, -no parity, -8 bits, -1 stop bit.
The transmission speed may be varied from 1200 to 9600 baud, using the
PERSONALIZATIONS menu on the CONTROL PANEL. Depending on the
distance of transmission, the recommended values for the transmission speed
are: 9600 baud 50m, 4800 baud 100m, 2400 baud 200m, 1200 baud 300m.
See the diagrams below for the connection procedure.

For connection with a modem use a cable standard.
See the diagram for connection with a modem.
3.3.4 Parallel (optional)
To be used for the connection of UPSs in parallel configuration. See the chapter “parallel version” on page 34.
3.3.5 SLOTS 2-1
Two slots are available inside the device, at the bottom, to use two
of the communication options
N.B. each card connected precludes the use of a standard RS232 port, as follows. The use of SLOT 2 (aux)
inhibits the use of RS232-2
3.3.6 REMOTE ALARMS (2 optional cards)
6 outputs: potential-free contacts for alarms (programmable from the display panel), 2 inputs (programmable from
the panel) and 1 12V DC maximum 100mA auxiliary input.
3.3.7 MODEM (optional)
Model compatible with the communication standards between the TRI
POWER X33 HIP and the software provided.
N.B. the modem must be connected to an RS232 port (D and E), a
standard RS232 port may not therefore be used.
In order to gain access to the following cards, remove the metal protective panel.
Only trained and authorised personnel must gain access to this area
