  • Page 9 The wiring procedure for the FVR0.75AS1S-4 is given below as an example. For other inverter types, perform wiring in accordance with their individual terminal arrangement. ① Grounding terminal ( G) Be sure to ground either of the two grounding terminals for safety and noise reduction. It is stipulated by the Electric Facility Technical Standard that all metal frames of electrical equipment must be grounded to avoid electric shock, fire and other disasters.
  • Page 10  Driving 400 V series motor  If a thermal relay is installed in the path between the inverter and the motor to protect the motor from overheating, the thermal relay may malfunction even with a wiring length shorter than 50 m. In this situation, add an output circuit filter (option) or lower the carrier frequency (Function code F26: Motor sound (Carrier frequency)).
