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:-

no clearance.
Typical drive heat losses are 3% of operating load conditions.
Above are guidelines only and the operating ambient temperature of
the drive MUST be maintained at all times.

3.6. Guidelines for mounting (IP66 Units)
Before mounting the drive, ensure that the chosen location meets the environmental condition requirements for the drive shown in section 9.1
The drive must be mounted vertically, on a suitable flat surface
The minimum mounting clearances as shown in the table below must be observed
The mounting site and chosen mountings should be sufficient to support the weight of the drives
Using the drive as a template, or the dimensions shown above, mark the locations required for drilling
Suitable cable glands to maintain the ingress protection of the drive are required. Gland holes for power and motor cables are pre-moulded into
the drive enclosure, recommended gland sizes are shown above. Gland holes for control cables may be cut as required.
