1. Introduction
1.1 Safety instruction
The UPS must be installed and maintained exclusively by quailified
staff. See installation and operation instructions before connecting to
the supply.
The UPS must be installed with an earth connection. It has a high
leakage current. The first wire to be connected is the earth wire, which
must be connected to the terminal marked PE (yellow/green).
The UPS generates a leakage current of over 3.5 mA. The leakage
current of the load should be added to that of the UPS on the
protective earth wire.
The UPS needs a neutral connection to work properly. Operation
without Neutral may damage the unit.
A readily accessible disconnect device shall be incorporated in the
building installation wiring for permanently connected equipment.
The UPS generates hazardous electric voltages inside it even when
the input and/or battery switches are open. The inside of the UPS is
protected by safety guards that are not to be removed by non-qualified
staff. All installation and maintenance or other operations that entail
gaining access to the inside of the UPS require the use of tools and
are to be performed exclusively by qualified staff.
The UPS contains an energy source: the batteries. All terminals and
sockets may be powered even when the UPS is not connected to the
mains.
The total battery voltage is potentially hazardous: it may cause an
electric shock. The compartment containing the batteries is protected
by safety guards, which are not to be removed by non-qualified staff.

2
All battery installation and maintenance operations entail gaining
access to the inside of the UPS and require the use of tools: these
operations are to be performed exclusively by qualified staff.
The batteries replaced are to be considered as toxic waste and treated
accordingly. Dispose of used batteries according to the instructions.
Do not throw the batteries into fire: they could explode. Do not attempt
to open the battery casing: no maintenance work can be done on them.
In addition, the electrolyte is hazardous for the skin and eyes and may
be toxic.
Risk of explosion if battery is replaced by an incorrect type.
Do not turn on the UPS if you see any leaks of liquid or a white
powder residue.
Make sure that no water, liquid in general and/or other foreign matter
gets inside the UPS.
Under hazardous conditions, turn off the UPS at the “1/0” main power
switch and open all the isolators present (see the user manual to
locate the “1/0” main power switch and the isolators).
Do not open the battery fuse holders while the UPS is powering the
load from the batteries. An interruption of the battery DC voltage may
cause an electric arc and result in breakage of the equipment and/or
fire.
The energy required to power the load is provided by the batteries in
the event of a power failure. if the battery protection were open, the
load would be powered off.
Fuses have to be replaced with the same type if necessary.
To connect external battery cabinets, use the expansion cable
suggested by the manufacturer in this manual.

3.Installation
3.1 Unpacking
1. Cut the straps
2. Open the carton, take off wood board, accessory pack and PE form.
3. Remove carton upward and take out front PE form.
4. Put the wood board (removed at step2) as figure showed. Make sure
that the slide rests firmly against the pallet so it remains in place during
unloading operations. Pull the UPS from the front with caution when
sliding it off the pallet.
NOTE: All parts of the packaging should be kept for future use.

3.2 Package content
After opening the packaging, it is first necessary to check the contents.
The package must contain:
3.3 Connection
3.3.1 Installation requirements
Warning:
Installation must be performed by qualified personnel. The first
connection to perform is the protective conductor (earth cable),
which must be connected to the screw marketed .
The UPS, when inserted in an installation, does not alter the existing
neutral (system earthing) arrangements.

A differential switch upstream will also be triggered for a fault occurring
downstream of the UPS. In calculating reactivity of this switch, account
must be taken of the leakage current of the UPS (approx. 8 mA) plus that
of the load which come together on the UPS’s earth conductor.

The neutral arrangements are altered only if there is an isolating
transformer or when the UPS operates with a neutral that is disconnected
upstream.
In any case avoid connecting the output neutral with the input neutral
or to the earth as this could damage the UPS.
Reminder : The UPS needs a neutral connection to work properly.
Operation without Neutral may damage the unit.
For installation with change in system earthing arrangement or
galvanic isolation see below schematic
Fig.3-1 Change in SEA or Galvanic isolation

Notice: It is required to install an external isolating device against current
backfeed between Mains input and UPS. After the device is installed, it
must add a warning label with the following wording or the equivalent on
the external AC contactor: RISK OF VOLTAGE BACKFEED. Isolate the
UPS before operating on this circuit, then check for hazardous voltage
between all terminals. The current rating of T - AC contactor should be
more than 1.3 times of UPS capacity

3.3.2 UPS Wiring Connection
To make the mains power and load connections, follow the instructions
below:
Single phase input
Three phase input

16
1. Install a magneto-thermal switch (63A for 6 & 10kVA versions, 125A
for 15 and 20kVA versions) with intervention curve D upstream of the
machine (4 poles for three-phase versions, 2 poles for single-phase
versions).
2. The connection terminals to use for the input and output lines are
located on the backpanel. Unscrew the 4 screws located on the sides
of the cover (one on each side, see figure).
3. Remove the backpanel cover (see figure to the side).
Fig.3-3 Wiring connection
Single-phase version (9E6Ki only)
4. (SINGLE-PHASE CONNECTION 9E6KI): use 3 cables with cross-
section 6 mm2(EARTH, N and L) for the input, and 3 cables with
cross-section 6 mm2for the output (EARTH, N and L).
5. Connect the wires to the relative terminals, following exactly the
instructions given below:
Input line
a - Make sure that the magneto-thermal switch upstream is open.
b - Connect the earth wire to screw A.
c - Connect the neutral wire to terminal 2.
d - Connect the live wire to terminal 1.
Output line
a - Connect the earth wire to screw B.
b - Connect the neutral wire to terminal 3.
c - Connect the live wire to terminal 4.

17
R.E.P.O.
a - The REPO connection (between terminal 5 and 6) is normally open.
For more information please refer to the REPO section of this

6. Tighten the terminals well, close the backpanel cover and secure it with
the screws taken out earlier.
For 10 to 15kVA the suggested tighten force is 1.2~1.6Nm. For 20kVA,
the suggested tighten force is 2.5~3 Nm.
