Chapter 4 Installation guide
4.1 What this chapter contains
The chapter describes the mechanical installation and electrical installation.
• Only qualified electricians are allowed to carry out what described in this
chapter. Please operate as the instructions in Chapter 1 "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 until the POWER indicator is off after the
disconnection if the power supply is applied. It is recommended to use the
multimeter to monitor that the DC bus voltage of the drive is under 36V.
• 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.
4.2 Mechanical installation
4.2.1 Installation environment
The installation environment is the safeguard for the full play and long-term stable function of the VFD.
Check the installation environment as followings:
-10–+50°C
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.
The maximum relative humility should be equal to or less than 60% in
