1. Introduction
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 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. 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 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 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 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 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.
IP66 drives provide their own pollution degree 2 environments. IP20 drives must be installed in a pollution degree 2 environment,
mounted in a cabinet with IP54 or better.
Drives 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 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
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 Drives Sales
Partner for further assistance.
