The chapter describes the mechanical installation and electric installation.
•
Only qualified electricians are allowed to carry out what described in this chapter.
Please operate as the instructions in Safety Precautions. Ignoring these may
cause physical injury or death or damage to the devices.
•
Ensure the power supply of the VFD is disconnected during the operation. Wait for
at least the time designated after the disconnection if the power supply is applied.
•
The installation and design of the VFD should be complied with the requirement of
the local laws and regulations in the installation site. If the installation infringes the
requirement, our company will exempt from any responsibility. Additionally, if users
do not comply with the suggestion, some damage beyond the assured
maintenance range may occur.

3.1 Mechanical installation

3.1.1 Installation environment

-10° C–+50° C, and the temperature changing rate is less than 0.5° C/minute.
If the ambient temperature of the VFD is above 40° C, derate 1% for every
additional 1° C.
It is not recommended to use the VFD if the ambient temperature is above
50° C.
In order to improve the reliability of the device, do not use the VFD if the
ambient temperature changes frequently.
Please provide cooling fan or air conditioner to control the internal ambient
temperature below the required one if the VFD is used in a close space such as
in the control cabinet.
When the temperature is too low, if the VFD needs to restart to run after a long
stop, it is necessary to provide an external heating device to increase the
internal temperature, otherwise damage to the devices may occur.
RH≤90%
No condensation is allowed.
-40° C–+70° C, and the temperature changing rate is less than 1° C/minute.
The installation site of the VFD should:
keep away from the electromagnetic radiation source;
keep away from contaminative air, such as corrosive gas, oil mist and
