3. Check that the control accuracy of the load is the same of the inverter.
4. Check that the incoming supply voltage is correspondent to the rated voltage of
the inverter.
2.1.3 Environment
Check as follows before the actual installation and usage:
1. Check that the ambient temperature of the inverter is below 40°C. If exceeds,
derate 1% for every additional 1°C. Additionally, the inverter can not be used if the
ambient temperature is above 50°C.
Note: for the cabinet inverter, the ambient temperature means the air temperature
inside the cabinet.
2. Check that the ambient temperature of the inverter in actual usage is above -10°C.
If not, add heating facilities.
Note: for the cabinet inverter, the ambient temperature means the air temperature
inside the cabinet.
3. Check that the altitude of the actual usage site is below 1000m. If exceeds,
derate1% for every additional 100m.
4. Check that the humidity of the actual usage site is below 90% and condensation is
not allowed. If not, add additional protection inverters.
5. Check that the actual usage site is away from direct sunlight and foreign objects
can not enter the inverter. If not, add additional protective measures.
6. Check that there is no conductive dust or flammable gas in the actual usage site. If
not, add additional protection to inverters.
2.1.4 Installation confirmation
Check as follows after the installation:
1. Check that the load range of the input and output cables meet the need of actual
load.
2. Check that the accessories of the inverter are correctly and properly installed. The
installation cables should meet the needs of every component (including reactors,
input filters, output reactors, output filters, DC reactors, braking units and braking
resistors).
3. Check that the inverter is installed on non-flammable materials and the calorific
accessories (reactors and brake resistors) are away from flammable materials.
4. Check that all control cables and power cables are run separately and the
routation complies with EMC requirement.
5. Check that all grounding systems are properly grounded according to the
requirements of the inverter.
6. Check that the free space during installation is sufficient according to the
instructions in user’s manual.
7. Check that the installation conforms to the instructions in user’s manual. The drive
must be installed in an upright position.
8. Check that the external connection terminals are tightly fastened and the torque is
appropriate.
9. Check that there are no screws, cables and other conductive items left in the
inverter. If not, get them out.
2.1.5 Basic commissioning
Complete the basic commissioning as follows before actual utilization:
