5. Whether the altitude on the site is higher than 1000 m. If yes, derate the machine by 1%
for every increased 100 m.
6. Whether the ambient humidity is higher than 90% or condensation occurs. If yes, take
extra protective measures.
7. Whether there is direct sunlight or biological invasion in the application environment. If
yes, take extra protective measures.
8. Whether there is dust or inflammable and explosive gas in the application environment.
If yes, take extra protective measures.
2.1.4 Installation confirmation
Check the following items after the installation of the VFD is complete.
1. Whether the input power cables and motor cables meet the current-carrying capacity
requirements of the actual load.
2. Whether the peripheral accessories are correctly selected and properly installed, and
whether the installation cables meet the current-carrying capacity requirements of the
accessories, including the input reactor, input filter, output reactor, output filter, DC
reactor, brake unit, and brake resistor.
3. Whether the VFD is installed on non-flammable materials, and whether its heat-emitting
accessories (such as reactor and brake resistor) are kept away from inflammable
materials.
4. Whether all the control cables are wired separately from power cables, and whether
electromagnetic compatibility (EMC) specification requirements are taken into full
account during the wiring.
5. Whether all the grounding systems are properly grounded according to the
requirements of the VFD.
6. Whether all the installation spacings of the VFD meet the requirements stated in the
manual.
7. Whether the installation of the VFD meets the requirements stated in the manual.
8. Check that the external connection terminals are tightly fastened and whether the
torque meets the requirements.
9. Whether screws, cables, or other conductive items drop into the VFD. If yes, take them
out.
2.1.5 Basic commissioning
Complete the basic commissioning as follows before using the VFD.
1. Perform autotuning if required. Remove the motor load, if possible, to perform dynamic
parameter autotuning; and if the load cannot be removed, you can perform static
autotuning.
2. Adjust the ACC/DEC time according to the actual operation conditions of the load.
