  • Page 2 Thank you for purchasing CERUS Variable Frequency Drives! SAFETY INSTRUCTIONS Always follow safety instructions to prevent accidents and potential hazards from occurring. In this manual, safety messages are classified as follows: WARNING Improper operation may result in serious personal injury or death. Improper operation may result in slight to medium personal injury CAUTION or property damage.
  • Page 3 Wiring and periodic inspections should be performed at least 10 minutes after disconnecting the input power and after checking the DC link voltage is discharged with a meter (below DC 30V). Otherwise, you may get an electric shock. Operate the switches with dry hands. Otherwise, you may get an electric shock.
  • Page 4 OPERATING PRECAUTIONS (1) Handling and installation Handle according to the weight of the product. Do not stack the inverter boxes higher than the number recommended. Install according to instructions specified in this manual. Do not open the cover during delivery. Do not place heavy items on the inverter.
  • Page 5 Always apply permissible range of voltage to the each terminal as indicated in this manual. Otherwise, it could lead to inverter damage. (4) Operation precautions When the Auto restart function is selected, stay away from the equipment as a motor will restart suddenly after an alarm stop.
