Installation confirmation
After the installation of the inverter, please pay attention to check the installation of the inverter:
1. Does the current carrying capacity of the input power cable and motor cable meet the actual load requirements?
2. Is the selection of the peripheral accessories of the inverter correct and the installation accurate? Does the installed cable meet its current carrying capacity requirements? Includes input reactor, input filter, output reactor, output filter, and braking resistor.
3. Is the inverter installed on flame retardant materials? Are the heating accessories (reactors, braking resistors, etc.) kept away from flammable materials?
4. Have all the control cables been routed separately from the power cables? Whether the cabling takes into account EMC characteristics.
5. Have all the grounding systems been properly grounded according to the requirements of the inverter?
6. Is the installation spacing of all the inverters installed in accordance with the requirements of the manual?
7. Is the installation method of the inverter consistent with the requirements in the manual? Install as vertically as possible.
8. Confirm whether the external terminal of the inverter is tightened and whether the torque meets the requirements?
9. Are you sure that there are no screws, cables, or other conductive objects left inside the inverter? If you have one, take it out.
