3. Safety First
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 drive contains high voltage capacitors that take time to discharge after removal of the power supply. Before working on the
drive, ensure isolation of all voltage sources, this includes Main AC supply, Battery supply, UPS supply.
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.
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 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 drive 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 drive, including the specified environmental limitations.
Do not perform any flash test or voltage withstand test on the drive. Any
electrical measurements required should be carried out with the drive
disconnected.
Electric shock hazard! Disconnect and ISOLATE the drive 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 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 drive power terminals.
When installing the drive on any power supply where the phase-ground
voltage may exceed the phase-phase voltage (typically IT supply networks or
Marine vessels) it is essential that the internal EMC filter ground and surge
protection varistor ground (where fitted) are disconnected. If in doubt, refer
to your Sales Partner for further information.
Danger: Indicates a potentially hazardous situation other
than electrical, which if not avoided, could result in
damage to property.
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 EN 60947-2.
A disconnector with an integrated auxiliary contact that ensures under
all circumstances the switching devices break the load circuit prior to
opening of the main contacts of the disconnector (EN 60947-3).
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 drive 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/run input signals are
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 drive 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.
The drive must be installed in a pollution degree 2 environment, mounted in a
cabinet with IP54 or better.
The drive is 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 drive 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 which can switch state whilst the drive is running.
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 drive. In the case of suspected
fault or malfunction, contact your local Invertek Drives Sales Partner for
further assistance.
Do not operate the drive with any of the enclosure covers removed.
