3. When the altitude exceeds 1000m, derate by 1% for every increase of 100m. When the
altitude exceeds 3000m, consult the local INVT dealer or office for details.
4. Check that the humidity of the actual usage site is below 90% and condensation is not
allowed. If not, add additional protection VFDs.
5. Check that the actual usage site is away from direct sunlight and foreign objects can not
enter the VFD. 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 VFDs.
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 VFD 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, brake units and braking resistors).
3. Check that the VFD is installed on non-flammable materials and the calorific
accessories (reactors and braking 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 VFD.
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 VFD 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 VFD. If
not, get them out.
2.1.5 Basic commissioning
Complete the basic commissioning as follows before actual utilization:
1. Autotune. If possible, de-coupled from the motor load to start dynamic autotune. Or if
not, static autotune is available.
2. Adjust the ACC/DEC time according to the actual running of the load.
3. Commission the device via jogging and check that the rotation direction is as required.
If not, change the rotation direction by changing the wiring of motor.
4. Set all control parameters and then operate.
