Safety Instructions
INJ-4500 series is intended for professional incorporation into comp lete equipment or systems as part of a fixed
installation. If installed incorrectly it may present a safety hazard. The INJ-4500 series 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 INJ-4500 series,
including the specified environmental limitations.
Do not perform any flash test or voltage withstand test on the INJ-4500 series. Any electrical measurements
required should be carried out with the INJ-4500 series disconnected.
Electric shock hazard! Disconnect and ISOLATE the INJ-4500 series 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.
The level of integrity offered by the Optidrive control input functions – for example stop/start, forward 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 INJ-4500 series 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 ault reset function on any systems whereby this may cause a potentially dangerous
situation.
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 single phase input correspond to the rating of the Optidrive 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
Danger : Indicates a risk of electric shock, which, if not
avoided, could result in damage to the equipment and
possible injury or death.
