Installing
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. Perform operations following the instructions
presented in Safety precautions. Ignoring the safety precautions may result in
device damage or injury or even death.
Ensure the VFD power is disconnected before installation. If the VFD has been
powered on, disconnect the VFD from the power, wait at least the time
specified on the VFD, and ensure the POWER indicator is off. It is
recommended that a multimeter should be used to check and ensure the VFD
DC bus voltage is lower than 36V.
VFD installation must be designed and performed according to applicable local
laws and regulations. INVT is not liable or responsible for any installation that
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
The VFD installation environment is essential for the VFD to run with best performance in long terms.
Install the VFD in an environment compliant with the following requirements.
Environment
Condition
Installation site
Indoor
Ambient
temperature
-10
–+50°C
When the ambient temperature exceeds 40°C, derate by 1% for every
temperature increase of 1°C.
It is not recommended that the VFD be used when the ambient
temperature exceeds 50°C.
In order to ensure reliability, do not use the VFD in cases where the
temperature changes rapidly.
When the VFD is used in closed space such as a control cabinet, use the
cooling fan or air conditioner to prevent the internal temperature from
exceeding the allowed temperature.
When the temperature is too low, install an external heating device
before running the VFD that has been powered off for a long time, which
eliminates the freeze inside the VFD. Otherwise, the VFD may be
damaged.
Humidity
The relative humidity (RH) of the air is less than 90%.
Condensation is not allowed.
