4.1 What this chapter contains
This chapter introduces the mechanical and electrical installations of the VFD.
Only 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 equipment 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.

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 e.g. 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 an 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.
