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.
Danger: Indicates a potentially hazardous situation
other than electrical, which if not avoided, could
result in damage to property.
This variable speed drive product (TECDrive) 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 TECDrive 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 TECDrive, including the specified environmental limitations.
Do not perform any flash test or voltage withstand test on the TECDrive. Any electrical measurements required should be carried
out with the TECDrive disconnected.
Electric shock hazard! Disconnect and ISOLATE the TECDrive 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
multi-meter 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. 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.
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 2006/42/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 TECDrive 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 TECDrive 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.
IP20 drives must be installed in a pollution degree 2 environment, mounted in a cabinet with IP54 or better.
TECDrives 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 TECDrive 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
Ensure that all terminals are tightened to the appropriate torque setting
Do not attempt to carry out any repair of the TECDrive. In the case of suspected fault or malfunction, contact your local Invertek
Drives Sales Partner for further assistance.

3.4. 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 TECDrive 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:-

4.2. Protective Earth (PE) Connection
Grounding Guidelines
The ground terminal of each TECDrive should be individually connected DIRECTLY to the site ground bus bar (through the filter if installed).
TECDrive 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
As with all inverters, a leakage current to earth can exist. The TECDrive 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
•The device must be suitable for protecting equipment with a DC component in the leakage current
•Individual ELCBs should be used for each TECDrive

Power & Control Wiring
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.
4.3. Incoming Power Connection
4.3.1. Cable Selection
•For 1 phase supply, the mains power cables should be connected to L1/L, L2/N.
•For 3 phase supplies, the mains power cables should be connected to L1, L2, and L3. Phase sequence is not important.
•For compliance with CE and C Tick EMC requirements, refer to section 4.10 EMC Compliant Installation on page 15.
•A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the TECDrive 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. Maximum dimensions are given in section 9.2.
4.3.2. 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 9.2 Rating Tables. 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; 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 TECDrive Power terminals as defined in IEC60439-1 is 100kA.
4.3.3. Optional Input Choke
•An optional Input Choke is recommended to be installed in the supply line for drives 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)
oThe 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. Part numbers are
shown in the table.

4.4. 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 TECDrive 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.
•The motor earth must be connected to one of the TECDrive earth terminals.
•Maximum permitted motor cable length for all models: 100 metres shielded, 150 metres unshielded.
4.5. 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.

4.6. Control Terminal Wiring
•All analog signal cables should be suitably shielded. Twisted pair cables are recommended.
•Power and Control Signal cables should be routed separately where possible, and must not be routed parallel to each other.
•Signal levels of different voltages e.g. 24 Volt DC and 110 Volt AC, should not be routed in the same cable.
•Maximum control terminal tightening torque is 0.5Nm.
•Control Cable entry conductor size: 0.05 –2.5mm2/ 30 –12 AWG.
4.7. Using the REV/0/FWD Selector Switch (Switched Version Only)
By adjusting the parameter settings the TECDrive can be configured for multiple applications and not just for Forward or Reverse.

This parameter allows a 2nd ramp time to be programmed into the drive.
This ramp time is automatically selected in the case of a mains power loss if P-05 = 2 or 3. When set to 0.00, the drive will coast to
stop.
When using a setting of P-15 that provides a “Fast Stop” function, this ramp time is also used.
In addition, if P-24 > 0, P-02 > 0, P-26=0 and P-27 = P-02, this ramp time is applied to both acceleration and deceleration when
operating below minimum speed, allowing selection of an alternative ramp when operating outside of the normal speed range,
which may be useful in pump and compressor applications.

The Skip Frequency function is used to avoid the TECDrive operating at a certain output frequency, for example at a frequency which
causes mechanical resonance in a particular machine. Parameter P-27 defines the centre point of the skip frequency band, and is
used in conjunction with P-26. The TECDrive output frequency will ramp through the defined band at the rates set in P-03 and P-04
respectively, and will not hold any output frequency within the defined band. If the frequency reference applied to the drive is
within the band, the TECDrive output frequency will remain at the upper or lower limit of the band.
