1. Introduction
1.1. Important Safety Information
Please read the IMPORTANT SAFETY INFORMATION below, and all Warning and Caution information elsewhere.
Danger: Indicates a risk of electric shock,
which, if not avoided, could result in damage to
the equipment and possible injury or death.
This variable speed drive product (Optidrive) is intended
for professional incorporation into complete equipment or
systems as part of a fixed installation. If installed incorrectly
it may present a safety hazard. The Optidrive uses high
voltages and currents, carries a high level of stored electrical
energy, and is used to control mechanical plant that may
cause injury. Close attention is required to system design
and electrical installation to avoid hazards in either normal
operation or in the event of equipment malfunction. Only
qualified electricians are allowed to install and maintain this
product.
System design, installation, commissioning and maintenance
must be carried out only by personnel who have the
necessary training and experience. They must carefully
read this safety information and the instructions in this Guide
and follow all information regarding transport, storage,
installation and use of the Optidrive, including the specified
environmental limitations.
Do not perform any flash test or voltage withstand test on the
Optidrive. Any electrical measurements required should be
carried out with the Optidrive disconnected. Internal surge
arrestors are fitted, intended to protect against damage due
to mains borne spikes, which will result in the product failing
the flash test.
Electric shock hazard! Disconnect and ISOLATE the Optidrive
before attempting any work on it. High voltages are present
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
per 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.
Within the European Union, all machinery in which this product
is used must comply with Directive 98/37/EC, Safety of
Machinery. In particular, the machine manufacturer is responsible
for providing a main switch and ensuring the electrical equipment
complies with EN60204-1.
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.
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.
The entry of conductive or flammable foreign bodies should be
prevented. Flammable material should not be placed close to
the drive.
Relative humidity must be less than 95% (non-condensing).
Ensure that the supply voltage, frequency and no. of phases (1 or
3 phase) correspond to the rating of the Optidrive as delivered.
Never connect the mains power supply to the Output terminals
U, V, W.
Do not install any type of automatic switchgear between the
drive and the motor. This may cause the drive protection to
activate, resulting in a trip and loss of operation.
Wherever control cabling is close to power cabling, maintain
a minimum separation of 100 mm and arrange crossings at
90 degrees.
Ensure that all terminals are tightened to the appropriate
torque setting.
Do not attempt to carry out any repair of the Optidrive. In the
case of suspected fault or malfunction, contact your local Invertek
Drives Sales Partner for further assistance.
Danger: Indicates a potentially hazardous situation
other than electrical, which if not avoided, could
result in damage to property.

2.1.4. Low Harmonic Variants
The majority of the Optidrive Eco product range is based on a low harmonic solution using film capacitor technology to achieve
compliance with EN 61000-3-12 without the need for any additional equipment. This standard specifies limits for harmonic currents
for equipment connected to public low-voltage systems with input current > 16A and <= 75A per phase. It is important to understand
which models from the product range are of the low harmonic technology which is detailed below.
The Optidrive Eco three phase 200V (200-240V) input and three phase 400V (380-480V) input drives frame sizes 2 up to and
including frame size 5 are a lower harmonic drive using film capacitor technology. Please refer to the product rating tables in section
2.1. Drive Model Numbers for confirmation.
General Information and Ratings
In short, this means that the low harmonic drives do not require an input choke and should not have one installed – drives outside of
the above frame sizes and supply voltage / number of phases, are of standard electrolytic capacitor design and could benefit from
the use of input chokes if further harmonic reduction is required.
2.2. Identifying the Drive by Model Number
Each drive can be identified by its model number, shown below. The model number is on the shipping label and the drive nameplate.
The model number includes the drive and factory fitted options.

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
enclosures:

discharge to safe voltage levels. Failure to observe this precaution could result in severe bodily injury or loss of life.
Only qualified electrical personnel familiar with the construction and operation of this equipment and the hazards involved
should install, adjust, operate, or service this equipment. Read and understand this manual and other applicable manuals
in their entirety before proceeding. Failure to observe this precaution could result in severe bodily injury or loss of life.

4.2. Protective Earth (PE) Connection
4.2.1. Grounding Guidelines
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.
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.
Electrical Installation
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 4.3. EMC Compliant Installation on page 20.

The cable shield should be terminated at the motor end using an EMC type gland allowing connection to the motor body through
the largest possible surface area. The shield must also be terminated at the drive end, as close as practically possible to the drive
output terminals. Where drives are mounted in a steel control panel enclosure, the cable screen may be terminated directly to the
control panel backplate using a suitable EMC clamp or gland fitted as close to the drive as possible. The drive earth terminal must
also be connected directly to this point, using a suitable cable which provides low impedance to high frequency currents. For IP55
and IP66 drives, connect the motor cable shield to the gland plate or internal ground clamp.

Control Cable
8
A shielded cable with low impedance shield. Twisted pair cable is recommended for analog signals.
Connect the Optidrive according to section 4.9. Control Terminal Wiring, ensuring that motor terminal box connections are correct.
There are two connections in general: Star and Delta. It is essential to ensure that the motor is connected in accordance with the
voltage at which it will be operated. For more information, refer to section 4.6. Drive and Motor Connection.
It is recommended that the power cabling should be 4-core PVC-insulated screened cable, laid in accordance with local industrial
regulations and codes of practice.

4.4. Incoming Power Connection
Power should be connected to the L1 and L2 terminals for single phase drives, L1, L2 and L3 for three phase drives. Phase
sequence is not important.
For compliance with CE and C Tick EMC requirements, a symmetrical shielded cable is recommended.
A fixed installation is required according to IEC61800-5-1.
For units without an internal isolator / disconnect, a suitable disconnecting device installed between the Optidrive and the AC
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.
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 11.5. Output Power and Current ratings. The fuses must comply with any local codes or regulations in place. In
general, type gG (IEC 60269) or UL type J, T or CC 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.
When the power supply is removed from the drive, a minimum of 30 seconds should be allowed before re-applying the power.
A minimum of 10 minutes should be allowed before removing the terminal covers or connection.
The maximum permissible short circuit current at the Optidrive Power terminals as defined in IEC60439-1 is 100kA.
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
Electrical Installation
will result in a “Ph-Seq"trip.
4.5. Input Chokes
The majority of the Optidrive Eco product range is based on a low harmonic solution using film capacitor technology to achieve
compliance with EN 61000-3-12 without the need for any additional equipment. This standard specifies limits for harmonic
currents for equipment connected to public low-voltage systems with input current > 16A and <= 75A per phase. It is important to
understand which models from the product range are of the low harmonic technology which is detailed below.
The Optidrive Eco three phase 200V (200-240V) input and three phase 400V (380-480V) input drives frame sizes 2 up to and
including frame size 5 are a lower harmonic drive using film capacitor technology.
In short, this means that the low harmonic drives do not require an input choke and should not have one installed – drives outside
of the above frame sizes and supply voltage / number of phases, could benefit from the use of input chokes if further harmonic
reduction is required.
The low harmonic drives must NOT be used with input chokes. Please see section 2.1.4. Low Harmonic Variants on page 8
for a description of which drives fall into the low harmonic category. Input chokes may be required on the standard (non low
harmonic) drives to reduce the harmonics generated or if the incoming supply impedance is low or the fault level / short circuit
4
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.

4.6. Drive and Motor Connection
The drive inherently produces fast switching of the output voltage (PWM) to the motor compared to the mains supply, for motors
which have been wound for operation with a variable speed drive then there is no preventative measures required, however if the
quality of insulation is unknown then the motor manufacturer should be consulted and preventative measures may be required.
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 used, 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.
The motor earth must be connected to one of the Optidrive earth terminals.
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 cable screen should be terminated at the motor end using an EMC type gland allowing connection to the motor body through
the largest possible surface area.
Where drives are mounted in a steel control panel enclosure, the cable screen may be terminated directly to the control panel
using a suitable EMC clamp or gland, as close to the drive as possible.
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.
4.7. Motor Terminal Box Connections
Most general purpose motors are wound for operation on two supply voltage. This will be indicated on the nameplate of the motor.
The 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.
