3.5. Wiring of a control terminal
Observe the following when wiring.
- Use 0.3 to 1.5mm
2
solid/stranded wire (AWG 22 to 16) for control cables.
- Remove the sheath of a cable about 7mm (6mm for FLA, FLB, FLC and G/E) from the end of cable.
- Use a flat-headed screwdriver with its blade 0.6mm in thickness and 3.5mm in width.
- Screw tightening torque for the terminal block screws should be 0.5 to 0.6Nm.
N.B.: Keep the control signal cables 20cm or more separate from the power cables to prevent from
malfunctioning due to electromagnetic noise.
N.B.: Provide an inter-lock system stated in below, when using a programmable controller that has
the open collector output.
When the programmable controller is turned off with the inverter is on, the difference between
each control power potential will cause wrong signals to the inverter as shown in below figure.
Provide an inter-lock so that the programmable controller cannot be turned off when the
inverter power is alive.
