2.2 Power Terminal
The upper cover must be removed in order to connect the electrical leads.
Basically, the Power terminals are divided into three portions:
l
The Power line input, (R, S, T) receives power for the operation of the inverter.
l
The Motor line output, (U, V, W) delivers Variable Frequency output to motor leads.
l
Brake resistor connect to B, P, terminal. (The inscription of terminals may be PR or PB.)
Note: Must connect Earth properly.
!
WARNING: Never connect power line to U, V, W, P, N, B, PR, BR.
2.3 Connect Power line input to Inverter
!
WARNING and CAUTION
l
Between the power line and the inverter, add NFB for system protection.
l
There are static sensitive components inside the Printed Circuit Board. Avoid touching the boards or
components with your hands or metal objects.
l
Only the terminal screws may be touched with the insulated screwdrivers when connecting the leads.
l
Make sure to connect the power terminals tight and correctly.
l
Make sure that the power source supplies the correct voltage and is designed for the necessary current.
l
Make sure the motor is configured to match the input voltage.
l
Protective EARTH terminal marked with
must be connected properly.
l
Take care that the appropriate circuit breakers with the specified current rating are connected between the
power supply and the inverter.
2.4 Connect inverter output to Motor
!
WARNING
Do not insert contactors between inverter output and motor.
For every model, "U, V, W " are the three phase output terminals, they should be connected to motor leads
directly.
2.5 Control terminal connection
!
CAUTION
All the input/output control signal lines, or remote panel lines and communication lines must be laid separately
from the high current power/motor/brake lines. They must not be fed through the same cable conduit/trucking.
