1. WARNINGS
1.1 General warnings
• The Power+ drive must be tted by professionally qualied personnel on a
complete unit or system as part of a xed installation.
• This device features dangerous voltages, and consequently failure to
observe the instructions contained in this user manual may cause serious
harm to people and damage to things.
• The system design, installation, commissioning and maintenance of
the drive are operations that are reserved solely for qualied personnel,
who understand all of the safety warnings, installation, operating and
maintenance instructions contained in this user manual code +0300050EN,
available, including prior to purchase, at www.carel.com, under“Literature”.
1.2 Fundamental safety rules
Before performing any maintenance work:
• disconnect Power+ and external control circuits from the power
supply, moving the main system switch to“o”; wait at least 5 minutes;
• always check, using a suitable multimeter, that there is no dangerous
voltage across the terminals;
• always make sure the motor has stopped completely. Motors that
are still freely rotating may produce dangerous voltages at the Power+
terminals, even when this is disconnected from the power supply;
• check the temperature of the heat sink: coming in contact with the
heat sink may cause burns.
When Power+ is connected to the mains, motor terminals U, V, W are
live, even if the motor is not running.
Do not measure insulation resistance or dielectric rigidity directly on
Power+, or with Power+ connected.
The control terminals are isolated from the mains voltage. Nonetheless,
the relay outputs may have a dangerous control voltage even when Power+
is not connected to the mains.
The level of safety provided by the enabling inputs on Power+
(excluding the “Safety Torque O ” input when used in compliance with the
standards) is not sucient in critical applications without adopting
further independent safety measures. For all applications where malfunctions
may cause serious harm to people and damage to things, the risks must be
assessed and additional safety measures adopted
Observe all the general and local safety standards concerning
installations of high voltage devices, as well as the regulations for the correct
use of the personal protective equipment.
Use this device only for the purposes specied by the manufacturer.
Do not make any modications or replace any components unless
recommended by the manufacturer, as these actions may cause re, electric
shock or other damage.

2. INTRODUCTION
Power+ is a drive designed to control compressors with sensorless-brushless
permanent magnet (PM) motors (BLDC/BLAC) or asynchronous induction
motors. For the latter, vector or V/f control can be selected. The drives can
also be used in some applications with fans and pumps, and consequently
the device oers exible use in the air-conditioning and refrigeration
sectors. It is tted for panel installation or with heat sink outside of the panel.
Conguration and programming, as well as the Run/stop controls and speed
reference, are managed by a CAREL pCO controller or any controller device
via RS485 serial connection using the Modbus® protocol in master mode.
To suppress current harmonics:
• on single-phase models, during installation a toroidal coil, supplied with
the drive, needs to be connected for active power factor correction (PFC);
• on three-phase models, connection of a DC choke is optional (available for
purchase as an accessory), if compliance with EN61000-3-12 is required.
2.1 Functions and main features
In summary:
• compact dimensions for assembly in electrical panels;
• operation at ambient temperatures from -20 to 60°C;
• can be installed in residential and industrial environments;
• connection via serial network to Master programmable controller;
• network address can be congured by setting the dipswitches directly on
the drive;
• can control various types of compressors;
• safety digital input (Safety Torque O );
• dedicated input for PTC thermistor or thermostat to monitor motor
overtemperature;
• panel installation or with heat sink outside of the panel, to optimize the
dissipation of heat inside the electrical panel;
• electrical connections can be made without needing to remove the plastic
cover;
• programmable acceleration curve to adapt to the required specications
when starting compressor;
• high switching frequency to limit motor noise;
• detailed information on drive status via numerous read-only variables;
• protection functions for the drive (short-circuit, overcurrent, earth fault,
overvoltage and undervoltage on the bus, overtemperature), motor
(overtemperature and limitation of current delivered) and system (Safety
Torque O input, communication failure).
2.2 Models

3. INSTALLATION
Important: avoid installing the drive in environments with the
following characteristics:
• relative humidity higher than 95% or with condensation;
• strong vibrations or knocks;
• exposure to water sprays;
• exposure to aggressive and polluting atmospheres (e.g.: sulphur and
ammonia fumes, saline mist, smoke) to avoid corrosion and/or oxidation;
• strong magnetic and/or radio frequency interference (thus avoid
installation near transmitting antennae);
• exposure of the drive to direct sunlight and the elements in general.

3.3 Dimensions
The overall dimensions of the drive vary based on the size of the heat sink (size
1 and size 2 for models with forced air cooled nned heatsink and size 3 for
Coldplate models) and the type of assembly (panel or with heat sink outside
of the panel, see the paragraph on “Drilling and assembly”), as the position
of the fastening brackets aects the total height. The side brackets are only
needed for assembly with the heat sink outside of the panel. For single-phase
models, the dimensions increase because the coil for power factor control
circuit (PFC) also needs to be connected. For three-phase models space may
also be required for a DC choke for limiting the power factor. All the brackets
have a 5.5 mm diameter hole.

3.4 Drilling and assembly
For installation with the heat sink outside of the panel, make a hole with
dimensions of the dashed rectangle, where the heat sink will be  tted, and
holes for fastening the brackets. These are inserted in the slots between the
heat sink and the plastic cover. For panel installation, only use the top and
bottom brackets, which are inserted in the slots above and below the heat
sink.

Note:
• on single-phase models leave space to t the PFC coil;
• on three-phase models space may be needed to t a DC choke (see par.
3.8).
3.6 Electrical installation
Important:
• before carrying out any maintenance work, disconnect the drive and
the external control circuits from the power supply by moving the main
system switch to“o ”. Once power has been disconnected from the drive,
wait at least 5 minutes before disconnecting the electrical cables;
• always make sure the motor has stopped completely. Motors that
are still freely rotating may produce dangerous voltages at the Power+
terminals, even when this is disconnected from the power supply.

ENG
“Power+” +0300050EN - rel. 2.3 - 08.06.201211
Note: the control signals terminal unit 1...8 and the relay terminals unit
9, 10 are double isolated from each other and with respect to the power
terminal board.
Important:
• in the European Union, all units that incorporate the drive must comply
with the Machinery Directive 2006/42/EC. Specically, the manufacturer
of the unit is responsible for the installation of a main switch and the
conformity to standard EN 60204-1;
• for xed installations according to IEC61800-5-1, a disconnect device is
required on the circuit between the power supply and the drive;
• only use permanently wired power input connections; the drive must be
earthed: the earth wire must be sized for the maximum fault current that is
normally limited by the fuses or a circuit breaker.
3.7 Conformity to EMC standards
Power+ is designed in compliance with the high EMC standards. All models
are supplied with an internal EMC lter, designed to reduce the emissions
taken towards the power supply line in conformity with harmonised European
Standards. It is the installer’s responsibility that the device or system within
which Power+ is incorporated is in compliance with the Standards in force
in the country of use. The Standard in force within the European Union is the
EMC 2004/108/EC Directive. Power+ is intended to be incorporated inside
xed installation devices, only installed by specialised sta.
Conformity with the EMC Standard means that the indications given in the
“Electric connections” paragraph are respected and, as it also depends on
wiring topology, it must be checked on the nal machine as envisioned by
the Final Product Standard.
3.8 Electrical connections
For installation proceed as shown below, with reference to the general
connection diagram (par. 3.10).
Important:
the following warnings must be observed when connecting the drive:
• separate as much as possible the probe and digital input cables (at least 40
cm) from the power cables to avoid possible electromagnetic disturbance.
Never lay power cables (including the electrical panel cables) and probe
signal cables in the same conduits;
• the cables must be sized according to the table in paragraph 9.1;
• when the fuses are used, these must be chosen according to the data
shown in the table in paragraph 9.1, and must comply with the national
and local standards in force. In general, use type gG fuses for IEC and type
T for UL, with a blow time less than 0.5 s;
• when a magnetic circuit breaker (MCB) is used, it must be of type B, rated
according to the data shown in the table in paragraph 9.1;
• avoid installing cables connected to the control terminal block in the
immediate vicinity of power devices (contactors, circuit breakers, etc.).
Reduce the path of the cables as much as possible, and avoid spiral paths
that enclose power devices.
Use cables rated to 90 °C, and if the temperature of the terminals exceeds 85
°C, use cables rated to 105 °C. Use cable terminals suitable for the terminals
and the cables used. Loosen each screw and insert the cable ends, then
tighten the screws and lightly tug the cables to check correct tightness. For
fork cable terminals, do not exceed the maximum width shown in the gure.

Fig. 3.h
Important: the tightening torque is:
• power terminals: 1 Nm;
• control terminals: 0,5 Nm.
Important:
In the unscrewing phase, do not force the screw further when it is fully
home.
The drive must be earthed: to do this, use either the screw terminal (earth
symbol ), or the screw (PE symbol ) on the side of the heat sink, in accordance
with local standards in force. To minimise EMC problems, use a power cable
with earth wire included, connected to terminal . The power supply earth
must be connected directly to the earth bar in the electrical panel, without
branches to other devices; the earth wire size must be greater than or equal
to the phase wires; the earth impedance must be compliant with national
and local standards; in compliance with UL requirements, the protective
earth connections (PE) must be made using eyelet lugs. On single-phase
models, also connect the PFC coil. On three-phase models, where necessary
connect the optional DC choke in place of the jumper that closes terminals
C1 and C2. See the “Terminals C1 and C2” paragraph.
Power supply
Connect the power cables: for single-phase models connect the power
supply to terminals L1/L and L2/N, for three-phase models to terminals L1, L2,
L3; for the size of the cables and the type of fuses, see the table in paragraph
9.1.
Important:
• do not connect the power supply to terminals U, V, W;
• make sure the voltage, frequency and number of phases in the power
supply match the ratings of the specic model.
Terminals C1 and C2
Important:
The use of terminals C1 and C2 depends on the model and diers based on
the type of power supply: single-phase or three-phase.
Models with 200/240 Vac single-phase power supply
Connect the PFC coil supplied with the drive to terminals C1 and C2.
Important:
Never short-circuit terminals C1 and C2.
The PFC coil does not require connection to earth.
See paragraph 3.12 for dimensions of the PFC coil.

Fig. 3.k
Earth leakage current
As for all inverter devices, earth leakage current greater than 3,5mA may
occur. The drive is designed to produce the minimum possible leakage
current. The current depends on the length and the type of motor cable, the
eective switching frequency, the type of earth connection used and the
type of RFI lter installed.
If a residual-current circuit breaker (RCCB) is to be used, the following
conditions apply:
• it must be a type B device (suitable to protect the equipment against
leakage current with a DC component);
• Individual RCCBs should be used for each drive.
Motor
Connect the motor power cable: use four-wire cable, the impedance of the
earth wire must be less than or equal to the impedance of the phase wires.
For the size and maximum length of the cable according to the model, see
the table in paragraph 9.1. To ensure conformity to the EMC directive, use
shielded cable with the shield that covers at least 85% of the surface of the
cable, with low impedance for high frequency signals. The cable can also be
laid in steel and copper cableways.

Motor protector
Connect a PTC thermistor motor protector to terminals 4 and 5: use a cable
with a minimum cross-section of 1 mm2; alternatively, a Klixon thermostat
can be connected (see the general connection diagram). The PTC thermistor
must be selected so that at activation temperature the resistance is > 2600 .
Safety digital input
Connect the “Safety Torque O ” digital input to a safety device (for example,
a maximum pressure switch) with normally closed voltage-free contact, in
series with an external 24 Vac/24 Vdc voltage source, without needing to
observe the polarity for direct current (ref. A). When the contact is open, the
drive stops operating, bypassing the software control. If the Safety Torque
O function is not used, the input must be connected to the auxiliary 24
Vdc available on the terminal block, so as to enable correct operation of the
drive (ref. B).

Attention:
• Make sure that the cooling device is dimensioned and xed to the plate
in a way to dissipate the heat while keeping the temperature of the plate
below 70°C in the various operating conditions and that the overheating
alarm does not intervene.
• Make sure that the cooling device does not cause the formation of
condensate on the inner surface of the plate.
• Clean the contact surfaces of the Power+ plate and of the coldplate and
ensure they couple perfectly.
• The use of thermal compound or similar product, between the contact
surfaces of the Power+ and the coldplate allows better heat coupling.

4. STARTUP
Important: Power+ can pilot various types of compressors with
permanent magnetic motors (PM) brushless BLDC/BLAC sensorless or
asynchronous induction motors. To set the parameters of a particular
compressor, consult the values indicated by CAREL in the document
“Power+: compressors parameters tables”, code +0300051IE, available, also
prior to purchase, upon request.
4.1 Conguration
The conguration of the drive consists in setting the various types of
parameters that regard:
1. the network communication: network address, data communication
baudrate, data communication parity;
2. the selection of the type of motor control;
3. the motor plate data;
4. the motor electric data;
5. motor start-up;
6. the motor control in regenerative functioning mode (load deceleration
with high inertia);
7. the proportional and integral regulation (PI) of the speed.
If the motor electric data (e.g.. resistances, inductance) are not known or are
believed not to reect the eective data (for example due to the length of
the motor cable), the Autotuning function can be used. See paragraph 4.5.
Note: once the communication parameters are set and the type of
motor and control selected, the setting of the parameters of points 3...7
depends on the type of motor.
Network communication
Network address
The conguration and the programming of the Power+ drive, as well as
the run/stop commands and the speed reference are managed by a CAREL
pCO control from any BMS (Building Management System) via RS485 serial
connection with ModBus® protocol. The ModBus® network address that can
be set from 1 to 247. This number is made up from the base address that can
be set from the parameter and the address of the 4 dip-switches present on
the drive, which goes from 0 to 15. By changing the base address in steps of
16, the entire interval can be covered.

Important:
• Autotuning can only be performed when a motor is connected. At the
start of the procedure, the motor must be at a standstill;
• the end of the Autotuning procedure is signalled by the “Autotuning”
parameter and from bit7 of the “Status register”, which are automatically
taken back to 0.
4.6 Controls before commissioning
Before commissioning, check that:
• the drive output current is greater than or equal to the rated current or the
maximum envisioned for the motor;
• the work voltage range is correct
• the section of the power supply cables is correct;
• the maximum section and length of the motor cables is correct and that
they are connected in compliance with the wiring diagrams;
• all of the control inputs are connected correctly.
