Indicates a potentially hazardous situation which, if not
avoided, could result in damage to property.
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.
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.
The level of integrity offered by the Optidrive control 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.
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 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.
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.
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. 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.
Flammable material should not be placed close to the drive
Parameter P1-01 can be set to operate the motor at up to 120,000 rpm, hence use this parameter with care.
If it is desired to operate the drive at any frequency/speed above the rated speed (P1-09/ P1-10) of the motor, consult the
manufacturers of the motor and the driven machine about suitability for over-speed operation.
Carefully inspect the Optidrive before installation to ensure it is undamaged
The Optidrive VTC has an Ingress Protection rating of IP20 or IP)) depending on the model. Units should be installed in a suitable
enclosure.
Optidrives are intended for indoor use only.
Do not perform and flash test or voltage withstand test on the Optidrive. Any electrical measurements required should be carried out
with the Optidrive disconnected.
The entry of conductive or flammable foreign bodies should be prevented
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
Wherever control cabling is close to power cabling, maintain a minimum separation of 100 mm and arrange crossings at 90 degrees

3.2. Before Installation
Carefully unpack the drive and check for any signs of damage. Notify the shipper immediately if any exist.
Check the drive rating label to ensure it is of the correct type and power requirements for the application.
Store the Optidrive in its box until required. Storage should be clean and dry and within the temperature range –40°C to +60°C
3.3. General Installation
The Optidrive should be mounted in a vertical position only on a flat, flame resistant vibration free mounting using the integral mounting
feet.
The Optidrive must be installed in a pollution degree 1 or 2 environment only.
Do not mount flammable material close to the Optidrive
Ensure that the minimum cooling air gaps, as detailed in section 3.4 are left clear

Optidrive VTC –User Guide
8 www.invertek.co.uk
3.4. Enclosure mounting
For applications that require a higher IP rating than the IP20 offered by the standard drive, the drive must be mounted in a suitable metallic
enclosure. The following guidelines should be observed for these applications:
For IP20 Optidrives, install in a suitable enclosure, according to EN60529 if specific Ingress Protection ratings are required.
Enclosures should be made from a thermally conductive material
Where vented enclosures are used, there should be venting above and below the drive to ensure good air circulation –see the diagram
below. 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.
Enclosure Front View
Enclosure Side View
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:-

4.1. Grounding the Drive
This manual is intended as a guide for proper installation. Invertek Drives Ltd cannot assume responsibility for the compliance or the
non-compliance to any code, national, local or otherwise, for the proper installation of this drive or associated equipment. A hazard
of personal injury and/or equipment damage exists if codes are ignored during installation.
This Optidrive contains high voltage capacitors that take time to discharge after removal of the main supply. Before working on the
drive, ensure isolation of the main supply from line inputs. Wait ten (10) minutes for the capacitors to 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.
Grounding Guidelines
The ground terminal of each Optidrive should be individually connected DIRECTLY to the site ground bus bar (through the filter if installed).
Optidrive ground connections should not loop from one drive to another, or to, or from any other equipment. Ground loop impedance must
confirm to local industrial safety regulations. To meet UL regulations, UL approved ring crimp terminals should be used for all ground wiring
connections.
The drive Safety Ground must be connected to system ground. Ground impedance must conform to the requirements of national and local
industrial safety regulations and/or electrical codes. The integrity of all ground connections should be checked periodically.
Protective Earth Conductor
The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply conductor.
Safety Ground
This is the safety ground for the drive that is required by code. One of these points must be connected to adjacent building steel (girder, joist), a
floor ground rod, or bus bar. Grounding points must comply with national and local industrial safety regulations and/or electrical codes.
Motor Ground
The motor ground must be connected to one of the ground terminals on the drive.
Ground Fault Monitoring
If a system ground fault monitor is to be used; only Type B devices should be used to avoid nuisance tripping.
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.
When shielded cable is used for control and signal wiring, the shield should be grounded at the source end only, not at the drive end.
4.2. Wiring Precautions
Connect drive according to section 4.4 Connection Diagram, 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 Motor Terminal Box Connections.
For recommended cabling and wiring sizing, refer to section 9.2 Rating tables.
It is recommended that the power cabling should be 3-core or 4-core PVC-insulated screened cable, laid in accordance with local industrial
regulations and codes of practice.
4.3. Incoming Power Connection
For 1 phase supply power should be connected to L1/L, L2/N.
For 3 phase supplies power should be connected to L1, L2, and L3. Phase sequence is not important.
The Optidrive should be connected to a fixed supply using a suitable disconnecting device between the Optidrive and the AC Power
Source. The disconnecting device must conform to the local safety code / regulations.
The cables should be dimensions according to any local codes or regulations. Guideline dimensions are given in section 9.2.
Suitable fuses to provide wiring protection should be installed in the incoming supply line, according to the data in section 9.2. The fuses
must comply with any local codes or regulations in place. In general, IEC type gG or UL type T fuses are suitable. The operating time of
the fuses must be below 0.5 seconds.
Where allowed by local regulations, suitably dimensioned circuit breakers may be utilised in place of fuses. Thermal overload protection
is not required, as the Optidrive provides thermal protection for the motor and motor cable. Guideline dimensions are given in section
9.2.
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 5 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.
An Input Choke should be installed in the supply line for frame size 1 to 3 Optidrives where any of the following conditions occur:-
oThe incoming supply impedance is low or the fault level / short circuit current is high
oThe supply is prone to dips or brown outs
oAn imbalance exists on the supply (3 phase drives)
oAll installations of Frame Size 2 drives on 575 Volt Supply

In all other installations, an input choke is recommended to ensure protection of the drive against power supply faults. The
recommended chokes can be found in the Invertek Stock Drives Catalogue
For compliance with CE and C Tick EMC requirements, a symmetrical shielded cable is recommended.
4.4. Connection Diagram
4.5. Motor Connection and Cables
The motor should be connected to the Optidrive U, V, and W terminals.
To comply with EMC requirements, a shielded cable should be used, with the shield bonded to earth at the Optidrive and the motor.
4.6. 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.

4.7. Dynamic Brake Resistor Connections
For drives that have a dynamic brake transistor, an optional external braking resistor can be connected to +DC and BR when required. The brake
resistor circuit should be protected by a suitable thermal protection circuit. Further information can be found in the Advanced User Guide.
