4 Installation guidelines
4.1 What this chapter contains
This chapter introduces the mechanical and electrical installations of the VFD.
Only well trained and qualified professionals are allowed to carry out the
operations mentioned in this chapter. Please carry out operations according
to instructions presented in Safety precautions. Ignoring these safety
precautions may lead to physical injury or death, or device damage.
Ensure the VFD power is disconnected before installation. If the VFD has
been powered on, disconnect the VFD and wait for at least the time
designated on the VFD, and ensure the POWER indicator is off. You are
recommended to use a multimeter to check and ensure the VFD DC bus
voltage is below 36V.
Installation must be designed and done according to applicable local laws
and regulations. INVT does not assume any liability whatsoever for any
installation which breaches local laws and regulations. If recommendations
given by INVT are not followed, the VFD may experience problems that the
warranty does not cover.
4.2 Mechanical installation
4.2.1 Installation environment
Installation environment is essential for the VFD to operate at its best in the long run. The installation
environment of the VFD should meet the following requirements.

Indoors
Ambient
temperature
-10
–+50°
When the ambient temperature exceeds 40°C, derate 1% for every
additional 1°C.
It is not recommended to use the VFD when the ambient temperature is
above 50°C.
In order to improve reliability, do not use the VFD in cases where the
temperature changes rapidly.
When the VFD is used in a closed space such as control cabinet, use
cooling fan or air conditioner to prevent internal temperature from
exceeding the temperature required.
When the temperature is too low, if restart a VFD which has been idled for
a long time, it is required to install external heating device before use to
eliminate the freeze inside the VFD, failing to do so may cause damage to
the VFD.
Humidity
The relative humidity (RH) of the air is less than 90%.
