ATTENTION
Any battery cabinet must have its own fuses on its output terminals “+” and “-“.
Remember that those fuses must be able to open the dc voltage.
If using the “Rapid” fuse, type gG/gL NH,
the MAXIMUM size of the battery fuse must be below 2 times the nominal battery capacity.
If using the “Ultra Rapid” fuse, type aR NH,
the MAXIMUM size of the battery fuse must be below 2.5 times the nominal battery capacity.
For example: battery type 150Ah we can use 250A gG/Gl or 315A aR.

Pag. 52/53 MT-HC3TK15E1599NP-US 00
4.1.1 Residual Current Detector (RDC)
A differential switch (RCD) must be inserted into the mains supply input (CPStream).
The differential switch located CPStream must have the following characteristics:
- Sensitivity 500mA;
- sensitive to d.c and unidirectional pulses (class B)
- insensitive to transient current pulses
- class A or class B
- delay greater or equal to 0,1s
In the standard version, where there is no isolation transformer in the by-pass line, the neutral input from the mains
supply is directly connected to the output from the CPS.
INPUT NEUTRAL CONNECTED TO OUTPUT NEUTRAL
THE ELECTRICAL SYSTEMS LOCATED CPSTREAM AND DOWNSTREAM OF THE CPS ARE IDENTICAL
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 CPS,
possibly coordinated with those on the input.
4.2 Mains, load and battery connections
THE FOLLOWING OPERATIONS DESCRIBED IN THIS CHAPTER MUST BE PERFORMED BY
TRAINED PERSONNEL.
THE FIRST CONNECTION TO BE MADE IS THE GROUND/EARTH CONNECTION TO THE TERMINAL
MARKED 'PE'. THE CPS CANNOT OPERATE WITHOUT CONNECTION TO THE GROUND/EARTH SYSTEM.
Before connecting, ensure that that the CPS equipment is totally isolated from any external power sources, battery and
mains line, and that all of the CPS switches are open, in particular:
- the CPS mains supply input is completely isolated
- all of the switches on the CPS: SWIN, SWBY, SWOUT, SWMB, are in the OFF position
- the output switch of the battery cabinet is in the open position
- always ensure that no hazardous voltages are present by measuring with a multi-meter.
For the power cable connection to the CPS terminal board refer to installation diagram supplied with USER
MANUAL
.

MT-HC3TKE301406NP-US 00 pag 11/53
4.2.1 Configuration with single mains supply
NOTE: The feed must be three-phase
with neutral. The CPS cannot work
without input neutral (*).
F - For the installation of the protective
devices on the input, refer to the
“connection table”.
(*)The operation without input neutral
is admitted only with transformer
(delta-star) on the input line .
The links between the SWIN and SWBY switches are pre-fitted.
The cables must be terminated using pre-insulated crimp terminals and should be connected as shown in installation
diagram supplied.
4.2.2 Configuration with split bypass input
NOTE: The by-pass supply must be
three-phase with neutral. The CPS
cannot work without input neutral
on the by-pass line (*).
F - For the installation of the
protective devices on the input, refer
to the “connection table”.
(*) The operation without input
neutral is admitted only with
transformer (delta-star) on the input
bypass line .
- remove the links between mains
line and by-pass line
The cables must be terminated using
pre-insulated crimp terminals and
should be connected as shown in
installation diagram supplied.

Pag. 52/53 MT-HC3TK15E1599NP-US 00
4.3 Backfeed protection
The CPS 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 by-pass line during operation from the inverter. If the fault occurs when the CPS 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 CPStream 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 CPS input.
4.3.1 Emergency power off device (EPO)
The CPS 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 CPS
b - EPO switch (not provided).
On the CPS , the jumper on the EPO terminals (page 16) 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.

4.4 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 CPSMUST NOT OPERATE WITHOUT AN EARTH CONNECTION
Before making the connection, open all the switches on the device and ensure that the CPS is completely isolated from
the power sources: battery and AC power line. More specifically, check that:
- the CPS input line or lines are completely isolated;
- the battery cabinet disconnector / fuse (if present) is open;
- all the CPS disconnectors - SWIN, SWBY, SWOUT and SWMB - are in the open position;
- 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 CPS and with the battery cabinet, if present.
Input neutral
The power supply to the CPS input (by-pass line) must be three-phase with neutral.
The neutral conductor is necessary only on by-pass line.

4.6 Connection of signals and remote commands
To the position of the signal and remote connection, refer to the “INSTALLATION DRAWINGS” supplied with the
CPS.
4.6.1 EPO connector (emergency power off control)
If the jumper on the connector is opened, the voltage on the CPS output
will be cut.
The CPS is factory-fitted with the EPO terminals shortcircuited. If this
input is used, the CPS 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 CPS will keep the load powered using
the energy in the batteries.
4.6.2 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:
- ALARMS
- RL1 Bypass / fault, the contact changes position when the CPS switches the load onto the
by-pass line either during normal operation (e.g. due to overload) or as a result of a
fault in the inverter stage;
- RL2 Battery discharging, the contact changes position when the load is powered from the
battery due to a mains power failure;
- RL3 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);
- COMMAND
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 CPS switches the power supply of
the load onto the by-pass line (load is not protected should there be a mains outage).
- In “EMERGENCY OPERATION”,
if the STOP INVERTER command is received, the CPS shuts down (load is not
powered).
With the jumper present, the CPS remains switched on the by-pass line when the
mains power supply is restored.
With no jumper present, the CPS will restart in NORMAL OPERATION.

MT-HC3TKE301406NP-US 00 pag 17/53
The position of the contacts shown is without the alarm present. The contacts can take a max. current of 1A with
250Vac.

display panel), 2 inputs (programmable from the panel) and one 12V DC
maximum 100mA auxiliary input.
4.6.7 MULTI I / O (optional)
The function of this accessory is to convert external signals from the CPS(e.g. temperature of environment, temperature
of battery premises, etc.) into signals by means of relay contacts or via serial output RS485 in MODBUS protocol.
It has the following characteristics:
- 8 inputs (e.g. humidity, smoke, etc. sensors)
- communication with the CPS via serial port
- 8 relays configurable with 8 events on the CPS
- RS232 output port with configurable messages
- RS 485 output port MDBUS /JUBUS with configurable messages.
4.6.8 REMOTE PANEL (OPTIONAL)
The remote panel allows the CPS to be monitored from a distance and the user to have a detailed overview of the state
of the machine in real time. Using this device, it is possible to keep the electrical mains, output and battery
measurements etc, under control and to detect any alarms.
For details relative to use and connection, refer to the specific manual.
4.6.9 Dual Bus System – UGS (optional)
Two independent systems may be configured with Dual Bus with a single source or a separate source.
The synchronization option (UGS) keeps the outputs of the two systems always synchronized, regardless of the input
variations and when the system is running from the battery. Each system may be made up of a maximum of 4 parallel-
connected CPSs. This system has been designed for configurations using STSs (Static Transfer Switches) since this
guarantees switching from one uninterruptible source to another without affecting the loads.

4.6.10 SWOUT and SWMB aux - External temperature sensor(optional).
A = connection to external output CPS switch
auxiliary;
B = connection to external bypass CPS switch
auxiliary ;
T = external temperature sensor connection.
SWOUT and SWMB aux
Terminals to be used for the connection of the
auxiliary contacts of switches inserted in the
CPS system, see also the section on “Insertion
of additional system sectioning devices” on
page 35.
Inserting additional disconnectors to
supplement those already in the CPS means
that the whole equipment can be replaced
without interrupting the power supply to the
load.
- Q01 additional output disconnector, Q02
additional disconnector of the external
maintenance by-pass.
The auxiliary contacts Q02 must be connected
to terminals B.
Contact Q02 must be in the opposite position
(auxiliary open with switch closed, vice versa
with switch open)
