at the terminals and within the drive for up to 10 minutes after
disconnection of the electrical supply. Always ensure by using a
suitable multimeter that no voltage is present on any drive power
terminals prior to commencing any work.
Where supply to the drive is through a plug and socket connector,
do not disconnect until 10 minutes have elapsed after turning off
the supply.
Ensure correct earthing connections and cable selection as
defined by local legislation or codes. The drive may have a
leakage current of greater than 3.5mA; furthermore the earth
cable must be sufficient to carry the maximum supply fault current
which normally will be limited by the fuses or MCB. Suitably rated
fuses or MCB should be fitted in the mains supply to the drive,
according to any local legislation or codes.
Do not carry out any work on the drive control cables whilst
power is applied to the drive or to the external control circuits.
The “Safe Torque Off” Function does not prevent high voltages
from being present at the drives power terminals.
Within the European Union, all machinery in which this product is used
must comply with the Machinery Directive 2006/42/EC, Safety of
Machinery. In particular, the machine manufacturer is responsible for
ensuring that the electrical equipment complies with EN60204-1 and
providing a disconnecting device which must be one of the following
types:
A switch-disconnector, utilization category AC-23B (EN 60947-3).
A circuit breaker suitable for isolation in accordance with
For installation in other regions, conformance with local electrical
regulations and codes of practice must be adhered to.
The level of integrity offered by the Optidrive control input functions –
for example stop/start, forward/reverse and maximum speed, is not
sufficient for use in safety-critical applications without independent
channels of protection. All applications where malfunction could cause
injury or loss of life must be subject to a risk assessment and further
protection provided where needed.
The driven motor can start at power up if the enable input signal is present.
The STOP function does not remove potentially lethal high voltages.
ISOLATE the drive and wait 10 minutes before starting any work on it.
Never carry out any work on the Drive, Motor or Motor cable whilst
the input power is still applied.
The Optidrive can be programmed to operate the driven motor at
speeds above or below the speed achieved when connecting the
motor directly to the mains supply. Obtain confirmation from the
manufacturers of the motor and the driven machine about suitability for
operation over the intended speed range prior to machine start up.
Do not activate the automatic fault reset function on any systems
whereby this may cause a potentially dangerous situation.
IP55 and IP66 drives provide their own pollution degree 2
environments. IP20 drives must be installed in a pollution degree 2
environment, mounted in a cabinet with IP54 or better.
Optidrives are intended for indoor use only.
When mounting the drive, ensure that sufficient cooling is provided. Do
not carry out drilling operations with the drive in place, dust and swarf
from drilling may lead to damage.

3.6. Guidelines for Enclosure Mounting (IP20 Units)
IP20 drives are suitable for use in pollution degree 1 environments, according to IEC-664-1. For pollution degree 2 or higher
environments, drives should be mounted in a suitable control cabinet with sufficient ingress protection to maintain a pollution
degree 1 environment around the drive.
Enclosures should be made from a thermally conductive material.
Ensure the minimum air gap clearances around the drive as shown below are observed when mounting the drive.
Where ventilated enclosures are used, there should be venting above the drive and below the drive to ensure good air circulation.
Air should be drawn in below the drive and expelled above the drive.
In any environments where the conditions require it, the enclosure must be designed to protect the Optidrive against ingress of
airborne dust, corrosive gases or liquids, conductive contaminants (such as condensation, carbon dust, and metallic particles) and
sprays or splashing water from all directions.
High moisture, salt or chemical content environments should use a suitably sealed (non-vented) enclosure.
The enclosure design and layout should ensure that the adequate ventilation paths and clearances are left to allow air to circulate
through the drive heatsink. Invertek Drives recommend the following minimum sizes for drives mounted in non-ventilated metallic

Adequate safety earthing must be provided in accordance with local wiring rules and codes of practice. The ground terminal of
each Optidrive should be connected back to the common safety earth bar to maintain touch potentials within safe limits. The ground
terminal of each Optidrive should be individually connected DIRECTLY to the site ground bus bar (through the EMC filter if installed).
Optidrive ground connections should not loop from one drive to another, or to, or from any other equipment. Ground impedance must
conform to local industrial safety regulations and/or electrical codes.
To meet UL regulations, UL approved ring crimp terminals should be used for all ground wiring connections.
The integrity of all ground connections should be checked periodically.
4.2.2. Protective Earth Conductor
The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply conductors.
4.2.3. Motor Ground
The driven motor must be locally connected to a suitable ground location to maintain touch potentials within safe limits. In addition, the
motor ground must be connected to one of the ground terminals on the drive.
4.2.4. Ground Fault Monitoring
As with all inverters, a leakage current to earth can exist. The Optidrive is designed to produce the minimum possible leakage current
whilst complying with worldwide standards. The level of current is affected by motor cable length and type, the effective switching
frequency, the earth connections used and the type of RFI filter installed. If an ELCB (Earth Leakage Circuit Breaker) is to be used, the
following conditions apply:
A Type B Device must be used.
Electrical Installation
Individual device should be used for each Optidrive.
The device must be suitable for protecting equipment with a DC component in the leakage current.
The device should be not sensitive to high frequency leakage current.
4.2.5. Shield Termination (Cable Screen)
The safety ground terminal provides a grounding point for the motor cable shield. The motor cable shield connected to this terminal
(drive end) should also be connected to the motor frame (motor end). Use a shield terminating or EMI clamp to connect the shield to
the safety ground terminal, refer to section 4.13. EMC Compliant Installation on page 28.

4.3. Incoming Power Connection
NOTE For IP20 Frame Size 8 it is important that the input supply phase orientation is correct, i.e. L1>L1, L2>L2, L3>L3, failure to do so
will result in a “Ph-Seq" trip.
Ensure there is at least 30 seconds between each power-on.
4.3.1. Suitability
All Optidrive P2 models are designed for use on a single phase or balanced three phase supply depending on the model.
For all models and ratings when working with an IT Supply network, or any power supply type where the phase to earth voltage may
exceed the phase to phase voltage (such as ungrounded supplies), the internal EMC filter and surge protection must be disconnected before
connecting the supply. Refer to section 10.6. Internal EMC Filter and Varistors – Disconnection Procedure on page 76 for further information.
For three phase supply models, a maximum of 3% imbalance is allowed between phases.
4.3.2. Cable Selection
For 1 phase ac supply, power should be connected to L1/L, L2/N.
For a DC Supply, the main power cables should be connected to L1/L, L2/N.
For 3 phase ac supplies, the mains power cables should be connected to L1, L2, and L3. Phase sequence is not important. Neutral
connection is not required.
For compliance with CE and C Tick EMC requirements, refer to section 4.13. EMC Compliant Installation on page 28. A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the Optidrive
and the main Power Source. The disconnecting device must conform to the local safety code / regulations (e.g. within Europe,
EN60204-1, Safety of machinery).
The cables should be dimensioned according to any local codes or regulations. Maximum dimensions for each drive model are
given in section 10.2. Input/Output Power and Current Ratings on page 72.
4.3.3. Fuse / Circuit Breaker Selection
Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming supply line, according to
the data in section 10.2. Input/Output Power and Current Ratings on page 72. The fuses must comply with any local codes or regulations in place. In general, type gG (IEC 60269) or UL type J fuses are
suitable (exception: Eaton Bussmann FWP series must be used for size 6A & 6B IP20 models); however in some cases type aR
fuses may be required. The operating time of the fuses must be below 0.5 seconds.
Where allowed by local regulations, suitably dimensioned type B MCB circuit breakers of equivalent rating may be utilised in
place of fuses, providing that the clearing capacity is sufficient for the installation.
The maximum permissible short circuit current at the Optidrive Power terminals as defined in IEC60439-1 is 100kA.
The Optidrive provides thermal and short circuit protection for the connected motor and motor cable.

4.3.4. Input Choke
An optional Input Choke is recommended to be installed in the supply line for drives where any of the following conditions occur:
The incoming supply impedance is low or the fault level / short circuit current is high.
NOTE For IP20 Frame Size 8 the input current level will vary according to supply impedance. At minimum a 1% line choke must be
installed. Installing a 4% line choke further helps towards minimising harmonic current distortion and total current levels. 1% and 4% line
chokes are available.
The supply is prone to dips or brown outs.
An unbalanced supply system is used (3 phase drives) where the voltage levels during on load operation exceed the designed 3%
capacity of the Optidrive.
The power supply to the drive is via a busbar and brush gear system (typically overhead Cranes).
In all other installations, an input choke is recommended to ensure protection of the drive against power supply faults.
4.4. Operation of 3 Phase drives from a Single Phase Supply
A special function of Optidrive P2 allows all drives designed for operation on 3 phase supplies to be operated on a single phase
supply of the correct rated voltage at up to 50% of the nominal capacity.
For Example, Model Number ODP-2-64450-3KA4N can be operated on a single phase supply, 380 – 480 volts, with the
maximum output current limited to 45 Amps.
The supply must be connected to the L1 and L2 terminals of the drive.
4.5. Operation with DC Power Supply or Common DC Bus
Optidrive P2 models provide terminals to directly connect to the DC Bus for applications which require this. For further information on
using the DC Bus connections, please refer to your Invertek Drives sales Partner.
4.6. Motor Connection
The drive inherently produces fast switching of the output voltage (PWM) to the motor compared with operation of the motor
directly from the mains supply. Most modern industrial motors are wound for operation with a variable speed drive and will have
insulation rated accordingly. However, on some motors the quality of insulation may be insufficient or unknown. In such cases the
motor manufacturer should be consulted and preventative measures may be required prior to operating with the drive.
The motor should be connected to the Optidrive U, V, and W terminals using a suitable 3 or 4 core cable. Where a 3 core cable
is utilised, with the shield operating as an earth conductor, the shield must have a cross sectional area at least equal to the phase
conductors when they are made from the same material. Where a 4 core cable is utilised, the earth conductor must be of at least
equal cross sectional area and manufactured from the same material as the phase conductors.
Automatic switchgear should not be installed between the drive output and the motor, opening and closing contacts in this circuit
whilst the drive is energised will inevitably reduce the lifetime of the drive and could cause product failure. If an isolator is required
to be placed between the drive and the motor in order to comply with local regulations, the device must not be operated when the
drive is running.
For compliance with the European EMC directive, a suitable screened (shielded) cable should be used. Braided or twisted type
screened cable where the screen covers at least 85% of the cable surface area, designed with low impedance to HF signals are
recommended as a minimum. Installation within a suitable steel or copper tube is generally also acceptable.
The motor earth must be connected to one of the Optidrive earth terminals to provide a low impedance path for common mode
leakage current to return to the drive. This is best achieved in practice by using a cable with suitable shielding which provides a low
impedance path at high frequencies, and ensuring correct, low impedance earth bonding of the motor cable at both ends. For further
information, refer to section 4.13. EMC Compliant Installation on page 28.
4.7. Motor Terminal Box Connections
Most general purpose motors are wound for operation on dual voltage supplies. This is indicated on the nameplate of the motor. This
operational voltage is normally selected when installing the motor by selecting either STAR or DELTA connection. STAR always gives
the higher of the two voltage ratings.

4.8. Connecting a Brake Resistor
Optidrive P2 units feature an internal brake transistor, fitted as standard for all models. The brake resistor should be connected to the
DC+ and BR terminals of the drive. These terminals are shrouded, and the shrouding should be removed to access the terminals.

Electrical Installation
The brake transistor is enabled using P1-05 (Refer to section 6.2. Parameter Group 1 – Basic Parameters on page 37 for further
information).
Software protection against brake resistor overload is carried out within the drive. For correct protection of the brake resistor, the
following settings are required:
Set P1-14 = 201 (where 201 is the default password setting for advanced parameter access).
Enter the resistance of the brake resistor in P6-19 (Ohms).
Enter the power of the brake resistor in P6-20 (kW).

Thermal Overload / Brake Resistor
with internal Over Temperature switch
It is highly recommended to equip the drive with a main
contactor in order to provide an additional thermal overload
protection for the braking resistor.
The contactor should be wired so that it will open when the
resistor overheats, otherwise the drive will not be able to
interrupt the main supply if the brake chopper remains closed
(short-circuited) in a fault situation.
It is also recommended to wire the thermal overload
protection to a digital input of the drive as an External Trip.
