3 Installing
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, and wait at
least the time marked on the VFD before carrying out an operation.
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.
3.1 Mechanical installation
3.1.1 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.
-10–+50°C. The air temperature change rate is less than 0.5°C/min.
When the ambient temperature exceeds 40°C, derate 1% for every
temperature increase of 1°C.
It is not recommended that the VFD be used (without load) 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.
The relative humidity (RH) of the air is less than 90%.
Condensation is not allowed.
