Check whether the ambient temperature of the VFD in actual use is lower than -10°C. If

yes, use heating facilities.
When the altitude exceeds 1000m, derate by 1% for every increase of 100m. When the

altitude exceeds 2000m, configure an isolation transformer at the VFD input end. It is
not recommended that the VFD be used at the altitude higher than 5000m.
Check whether the humidity of the actual usage site exceeds 90% and condensation

occurs. If yes, take additional protective measures.
Check whether the actual use site may be exposed to direct sunlight or may have the

chance of ingress of foreign objects. If yes, take additional protective measures.
Check whether there is dust, explosive gas, or flammable gas in the actual use site. If

yes, take additional protective measures.

2.5 Installation confirmation

Check the following after the VFD installation:
Check whether the load ranges of the input power cable and motor cable meet the

actual load requirement.
Check whether correct accessories are selected for the VFD, the accessories are

correctly and properly installed, and the installation cables meet the requirements of
all components (including the reactor, input filter, output reactor, output filter, DC
reactor, braking unit and braking resistor).
Check whether the VFD is installed on non-flammable materials and the

heat-radiating accessories (such as the reactor) are away from flammable materials.
Check whether all control cables and power cables are run separately and the routing

complies with EMC requirement.
Check whether all grounding systems are properly grounded according to the

requirements of the VFD.
Check whether all the installation clearances of the VFD meet the requirements in the

operation manual.
Check whether the installation conforms to the instructions in the operation manual.

It is recommended that the VFD be installed uprightly.
Check whether the external connection terminals of the VFD are tightly fastened and

the torque is appropriate.
Check whether there are screws, cables, or other conductive items left in the VFD. If

yes, get them out.
