HD2 IP55 High-ingress Protection Series Inverters
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 the inverters.
1.
Check whether the packing box is damaged or dampened. If yes, contact local dealers
or IMO 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 IMO 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
IMO 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 IMO 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 IMO 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 different?
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.
Note: For cabinet-type inverter, its ambient temperature is the air temperature inside the
cabinet.
