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 1 "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. Users 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.
Environment Condition
Installation
site
Indoors
Ambient
temperature
 -10
–+50°C;
 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 eg 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%;
 The max RH cannot exceed 60% in the environment where there are corrosive
gases.
