    8000m Series SAFETY INSTRUCTION Read this user manual thoroughly before installation, operation, maintenance or inspection of the variable frequency drive (VFD). In this manual, safety instructions are classified as “WARNING” or “CAUTION”. WARNING: Indicate a potentially dangerous situation which, if not avoided, can result in death or serious injury to personnel.
  • Page 7 8000m Series ■ Wiring ◎Ensure only qualified electrical engineering personnel for wiring work . Otherwise it can cause an electrical shock or damage to the VFD. ◎Make sure VFD is isolated from power supply by the circuit breaker. Otherwise it may cause electrical shock or a fire.
  • Page 8 8000m Series ■ Operating ◎It is only allowed to power on the VFD after the wirng is finished and its cover is reinstalled. It is strictly prohibit to remove the cover of VFD while power is on, otherwise it may cause electric shock.
  • Page 9 8000m Series ■ Maintenance ◎Never touch the VFD the connection terminals when power is on. Otherwise it may cause an electrical shock. ◎Only qualified electrical engineering personnal can be authorized to do the jobs of maintenance, checking, or parts replacement.
