1. Inspection upon receiving ■
Preface
Thank you for choosing the CT-2000FG/ FP inverter unit, this inverter unit is suitable for operating squirrel
cage induction motors. This manual is designed to ensure correct and suitable application. Read this manual
before attempting to install. If any problem occurred when negligence of manual. Please contact our
distributors or sales representatives.
※Application notes
▇ Please do not touch the cercuit boards and components immediately after the poweris was shut down.
▇ Wiring is prohibited when power on, please do not check the components and signal on the circuit
board when operation.
▇ Do not fit capacitors to the output side of the inverter in order to improve the power ratio.
▇ Run a motor that is within the capacity of the inverter unit.
▇ In case of fitting MC between inverter and motor to control motor operation, then the capacity of
inverter must be 6 times the capacity of motor.
Inspection upon receiving
A. Check that the model, the capacity and power voltage specifications are as ordered.
B. Check that no damage has occurred during transportation.
C. Check that none of the internal parts have been damaged or have fallen off.
D. Check that none of the connectors have been damaged or have fallen off.
E. Check that there is no loosening of the terminals or screws of each of the parts.
If said problems occurred when negligence of manual. Please contact our distributors or sales representatives

Installation and storage
1. Storage: If the equipment is not to be installed immediately, it should be stored in a clean and dry
location at ambient temperatures from 20℃to 55℃. The surrounding air must be free of corrosive
contaminants. And please input power a time per half year.
2. Installation place: Places where the peripheral temperature is from -10℃to 40℃, and where the
relative humidity is 90% or less. Avoid installing at places where there is dust, iron particles,
corrosive gas, water spray, direct sunlight or too much vibration. And places where has good
ventilation.
3. Please fix the inverter under the cooling fan if it is installed in the panel. The heating from inverter
will be discharged out of the panel to reduce the temperature and get the better effect of ventilation.
Notice : 10HP(contained) and above inverter are installed as following.
