2.1 Quick startup

2.1.1 Unpacking inspection

Check as follows after receiving products:
1. Check whether the packing box is damaged or dampened. If yes, contact local
dealers or Kruger offices.
2. Check the model identifier on the exterior surface of the packing box is
consistent with the purchased model. If no, contact local dealers or Kruger
offices.
3. Check whether the interior surface of packing box is abnormal, for example, in
wet condition, or whether the enclosure of the VFD is damaged or cracked. If yes,
contact local dealers or Kruger offices.
4. Check whether the name plate of the VFD is consistent with the model identifier
on the exterior surface of the packing box. If no, contact local dealers or Kruger
offices.
5. Check whether the accessories (including user's manual and control keypad)
inside the packing box are complete. If not, please contact with local dealers or
Kruger offices.

2.1.2 Checking before applying

Check the machine before beginning to use the VFD:
1. Check the load type to verify that there is no overload of the VFD during work
and check whether the power class of the VFD needs to be increased.
2. Check whether the actual running current of the motor is less than the rated
current of the VFD.
3. Check whether the control accuracy required by the load is the same with that of
the VFD.
4. Check whether the grid voltage is consistent with the rated voltage of the VFD.

2.1.3 Environment confirmation

Check as follows before the actual installation and usage:
1. Check whether the ambient temperature of the VFD exceeds 40°C. If it exceeds
40°C, derate 1% for every increase of 1°C. It is not recommended to use the VFD if
the ambient temperature exceeds 50°C.
Note: For the cabinet VFD, the ambient temperature means the air temperature
inside the cabinet.
