2 Precautions for Quick Application
2.1 What this chapter contains
This chapter introduces the basic principles required during installation commissioning. Users can
ensure quick installation commissioning by following these principles.
2.2 Unpack inspection
Check as follows after receiving products.
1. Check whether the packing box is damaged or dampened. If yes, contact local sellers or Sourcetronic
offices.
2. Check the model identifier on the exterior surface of the packing box is consistent with the purchased
model. If not, contact local sellers or Sourcetronic offices.
3. Check whether the interior surface of the packing box is improper, for example wet, or whether the
enclosure of the VFD is damaged or cracked. If yes, contact local sellers or Sourcetronic offices.
4. Check whether the nameplate of the VFD is consistent with the model identifier on the exterior surface
of the packing box. If not, contact local sellers or Sourcetronic offices.
5. Check whether the accessories (including user's manual, control keypad and expansion card units)
inside the packing box are complete. If not, contact local sellers or Sourcetronic offices.
2.3 Application confirmation
Check the following items before operating the VFD:
1. Verify the load mechanical type to be driven by the VFD, and check whether overload occurred to
the VFD during actual application, or whether the VFD power class needs to be enlarged.
2. Check whether the actual running current of load motor is less than rated VFD current.
3. Check whether the control precision required by the actual load is the same as the control precision
provided by the VFD.
4. Check whether the grid voltage is consistent with the rated VFD voltage.
5. Check whether the functions required need an optional expansion card to be available.
2.4 Environment confirmation
Check the following items before use:
1. Check whether the ambient temperature of the VFD during actual application exceeds 40°C, if yes,
derate 1% for every additional 1°C. In addition, do not use the VFD when the ambient temperature
exceeds 50°C.
Note: For a cabinet-type VFD, its ambient temperature is the air temperature inside the cabinet.
