ATTENTION!
Use proper cable lugs for the power and grounding connection cables.
ATTENTION!
Sensitive equipment such as PLCs, temperature controllers, and thermocouple cables, must be kept at
a minimum distance of 0.25 m (9.84 in) from the frequency inverter and from the cables connecting
the inverter to the motor.
DANGER!
Wrong cable connections:
- The inverter will be damaged if the power supply is connected to the output terminals (U/T1, V/T2,
or W/T3).
- Check all the connections before powering up the inverter.
- When replacing an existing inverter by a CFW-11, check if the installation and wiring are according
to the instructions listed in this manual.
