4 Installation Guidelines
4.1 What this chapter contains
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 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
Installation site
Environment
temperature
Humidity
Storage
temperature
Running
environment
condition
16 - 144
Indoor
-10~+50ºC
If the ambient temperature of the inverter is above 40ºC, derate 3% for every additional
1ºC.
It is not recommended to use the inverter if the ambient temperature is above 50ºC.
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.
When the temperature is too low, if the inverter 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 humidity should be equal to or less than 60% in corrosive air.
-30~+60ºC
The installation site of the inverter should:
- Keep away from an electromagnetic radiation source
- Keep away from contaminative air, such as corrosive gas, oil mist and flammable gas
- Ensure foreign objects, such as metal power, dust, oil. Water can not enter into the
inverter (do not install the inverter on the flammable materials such as wood)
