3 Installation Guidelines
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 after the disconnection if the power supply is applied.
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.
3.1 Mechanical installation
3.1.1 Installation environment
The installation environment is the safeguard for a full performance and long-term stable functions of the inverter. Check the installation environment as follows:
Environment Conditions
Installation site Indoor
Environment
temperature
-10°C~+50°C, and the temperature changing rate is less than 0.5°C/minute.
If the ambient temperature of the inverter is above 40°C, derate 3% for every
additional 1°C.
It is not recommended to use the inverter if the ambient temperature is above
50°C.
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.
Humidity
RH ≤ 90%
No condensation is allowed.
Storage
temperature
-40°C~+70°C, and the temperature changing rate is less than 1°C/minute.
Running environment
condition
The installation site of the inverter should:
keep away from the 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);
keep away from direct sunlight, oil mist, steam and vibration environment.
Altitude
Below 1000m
If the sea level is above 1000m, please derate 1% for every additional 100m.
Vibration ≤ 5.8m/s
2
(0.6g)
Installation direction
The inverter should be installed on an upright position to ensure sufficient
cooling effect.
Note:
Astraada DRV-22 series inverters should be installed in a clean and ventilated environment according to enclosure classification.
Cooling air must be clean, free from corrosive materials and electrically conductive dust.
3.1.2 Installation direction
The inverter may be installed on the wall or in a cabinet.
