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 inverter 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 inverter 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 important for a full performance and long-term stable
functions of the inverter. Check the installation environment as followings:
Environment Conditions
Installation site Indoor
Environment
temperature
-10~+50℃
If the ambient temperature of the inverter is above 40 , derate ℃ 1%
for every additional 1 . ℃
It is not recommended to use the inverter if the ambient
temperature is above 50 . ℃
In order to improve the reliability of the device, do not use the
inverter 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 inverter is used
in a close space such as in the control cabinet.
