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.
This variable speed drive product (BFI drive) 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 BFI 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 BFI drive, including the specified
environmental limitations.
Do not perform any flash test or voltage withstand test on
the BFI drive. Any electrical measurements required should
be carried out with the BFI drive disconnected. Internal
surge arrestors are fitted, intended to protect against
damage due to mains borne spikes, which will result in the
product failing the flash test.
Electric shock hazard! Disconnect and ISOLATE the BFI
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
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.
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 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 BFI 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 BFI 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.
IP55 drives can be installation in a pollution degree 2
environment. IP66 outdoor drives can be installed in a pollution
degree 4 environment. IP20 drives must be installed in a pollution
degree 1 environment. If it is necessary to install IP20 drives in an
environment with a higher pollution degree, then the drive must be
installed inside an enclosure that provides the drive with a pollution
degree 1 environment.
BFI drives are intended for indoor use only, unless specifically
stated as being suitable for installation outdoors and installed in
accordance with the Manufacturers guidelines.
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 BFI 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. This may cause the drive protection to activate,
resulting in a trip and loss of operation.
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 BFI drive. In the case
of suspected fault or malfunction, contact Beijer Electronics for
further assistance.
