Chapter 2 Quick startup

2.1 What this chapter contains

This chapter introduces the basic principles required during installation commissioning. Users can
realize 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 dealers or
HITACHI 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 HITACHI offices.
3. Check whether the interior surface of packing box is improper, for example, in wet
condition, or whether the enclosure of the inverter is damaged or cracked. If yes, contact
local dealers or HITACHI offices.
4. Check whether the nameplate of the inverter is consistent with the model identifier on the
exterior surface of the packing box. If not, contact local dealers or HITACHI offices.
5. Check whether the accessories (including user's manual, control keypad and extension
card units) inside the packing box are complete. If not, contact local dealers or HITACHI
offices.

2.3 Application confirmation

Check the following items before operating on the inverter.
1. Verify the load mechanical type to be driven by the inverter, and check whether overload
occurred to the inverter during actual application, or whether the inverter power class needs
to be enlarged?
2. Check whether the actual running current of load motor is less than rated inverter current.
3. Check whether the control precision required by actual load is the same with the control
precision provided by the inverter.
4. Check whether the grid voltage is consistent with rated inverter voltage.
5. Check whether the functions required need an optional extension card to be realized.

2.4 Environment confirmation

Check the following items before use.
1. Check whether the ambient temperature of the inverter during actual application exceeds
40° C, if yes, derate 1% for every additional 1° C. In addition, do not use the inverter when
the ambient temperature exceeds 50° C.
Note: For cabinet-type inverter, its ambient temperature is the air temperature inside the
cabinet.
2. Check whether ambient temperature of the inverter during actual application is below
-10° C, if yes, install heating facility.
