Important safety information

This variable speed drive product (Optidrive) is intended for professional incorporation into complete equipment or systems. If installed
incorrectly it may present a safety hazard. The Optidrive 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.
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 Optidrive, including the specified environmental limitations.
Please read the IMPORTANT SAFETY INFORMATION below, and all Warning and Caution information elsewhere.
Indicates a potentially hazardous situation which, if not
avoided, could result in injury or death.
Safety of machinery, and safety-critical applications
The level of integrity offered by the Optidrive control 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. Within the European
Union, all machinery in which this product is used must comply with Directive 89/392/EEC, Safety of Machinery. In particular, the
electrical equipment should comply with EN60204-1.
•
Optidrives should be installed only by qualified electrical persons and in accordance with local and national regulations
and codes of practice. The Optidrive has an Ingress Protection rating of IP20. For higher IP ratings, use a suitable
enclosure.
•
Electric shock hazard! Disconnect and ISOLATE the Optidrive 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.
•
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
•
The STOP function does not remove potentially lethal high voltages. ISOLATE the drive and wait 10 minutes before
starting any work on it
•
Parameter P-01 can be set to operate the motor at up to 60,000 rpm, hence use this parameter with care.
•
If it is desired to operate the drive at any frequency/speed above the rated speed (P-09/ P-10) of the motor, consult the
manufacturers of the motor and the driven machine about suitability for over-speed operation.
•
The fan (if fitted) inside of the Optidrive starts automatically when the heatsink temperature reaches approximately 45ºC.
•
Carefully inspect the Optidrive before installation to ensure it is undamaged
•
Indoor Use Only.
•
Flammable material should not be placed close to the drive
•
The entry of conductive or flammable foreign bodies should be prevented
•
Relative humidity must be less than 95% (non-condensing).
•
Ensure that the supply voltage, frequency and single phase input correspond to the rating of the Optidrive as delivered.
•
An isolator should be installed between the power supply and the drive.
•
Never connect the mains power supply to the Output terminals U, V, W.
•
Protect the drive by using slow-blowing HRC fuses or MCB located in the mains supply of the drive
•
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
•
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protection must be
provided in accordance with the National Electrical Code and any additional local codes
1.2.

Electromagnetic Compatibility (EMC)

Optidrive is designed to high standards of EMC and is optionally fitted with an internal EMC filter. This EMC filter is designed to reduce
the conducted emissions back into the supply via the power cables for compliance with harmonised European standards.
It is the responsibility of the installer to ensure that the equipment or system into which the product is incorporated complies with the
EMC legislation of the country of use. Within the European Union, equipment into which this product is incorporated must comply with
89/336/EEC, EMC.
For use on domestic supplies, screened motor cable must be used with the screen terminated to earth on both motor and drive
sides. The installation must be carried out by qualified installation engineers, observing good wiring practice such as power and signal
cable segregation and correct screening techniques to minimise emissions. When installed in this way, the Optidrive with built-in filter
has emission levels lower than those defined in EN61800-3 category C2 for 1
For cable lengths above 5m, the emission levels may exceed those defined by EN61800-3 cat C2. In this case, further mitigation
methods (such as fitting an external filter - Optifilter) must be employed if the emissions limits are to be upheld.
