PV500 series solar pumping inverters

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
Installation site
Environment
temperature
Humidity
Storage
temperature
Indoor
The ambient temperature of inverter is -10℃~50℃ while air
temperature change should be less than 0.5℃ per minute.
The inverter will be derated once ambient temperature exceeds 40℃. It
is not recommended to use the inverter if ambient temperature is above
50℃.
To ensure reliability, do not use the inverter if the ambient temperature
changes frequently.
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.
-40°C~+70°C. The temperature change rate is less than 1°C/minute.
