Safety Instructions I 03
Safety Instructions
INJ-4500 series is intended for professional incorporation into comp lete equipment or systems as part of a xed
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 qualied 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 specied environmental limitations.
Do not perform any ash 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 o the supply.
Ensure correct earthing connections and cable selection as per dened by local legislation or codes. The drive
may have a leakage current of greater than 3.5mA; furthermore the earth cable must be sucient to carry the
maximum supply fault current which normally will be limited by the fuses or MCB. Suitably rated fuses or MCB
should be tted in the mains supply to the drive, according to any local legislation or codes.
The level of integrity oered by the Optidrive control input functions – for example stop/start, forward and
maximum speed is not sucient 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 conrmation 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 sucient 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 ammable 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.

Before Installation
Installation Guide of the INJ-4500
• Carefully Unpack the INJ-4500 and check for any signs of damage.
Notify the shipper immediately if any exist.
INJ-4500 is installed on the motor with a specialized heat-sink custom design by INJUNGTECH.
1. Remove the current motor terminal box.
Note: The gasket installed on the original terminal box
and the screws should be kept and not thrown away.
3. Undo the 4 screws on the inverter.
5. Bolt down the four inner holes located inside
the drive down with the screws provided.
2. Place the heat-sink provided unto the motor. Connect the
motor wires to the inverter output lines. Use the screws from the
motor and bolt down the heatsink unto the motor. Note: The
original gasket should be placed before placing the heatsink.
4. Lift up the inverter top by loosening the gland and by
pushing in the terminal wires.
6. Close the top of the drive and bolt down the 4 corners
with the screws provided.

Wiring Diagram
This manual is intended as a guide for proper installation. Injungtech Co., 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 INJ-4500 contains high voltage capacitors that take time to discharge after removal of the main supply.
Before working on the drive, ensure isolation of the main supply from line inputs. 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 qualied 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.
