INSTALLATION
3.1 Installation Precautions
█
Do not install the inverter in the following locations.
· Locations subject to direct sunlight.
· Locations subject to water vapor or high humidity.
· Locations with large amount of oil mist, dust or fiber dust.
· Locations where rain water, water drops or oil drops may come in contact.
· Locations suject to corrosive gases, explosive gases or flammable gases.
· Installation onto flammable materials such as wood or near flammable materials.
· Locations subject to vibration.
█
Make sure that ambient temperature is within the specifications.
If the inverter is installed near a heat generating device or is housed in a panel,
surrounding temperature will increase, thus reducing the life of the inverter.
When housing the inverter in a panel, give sufficient consideration to cooling
method and panel size.
○ Allowable ambient temperature: -10℃ to +50℃
(5.5kW/7.5kW/11kW/15kW Temperature for –10℃ to +40℃ light load specification)
(Ambient temperature should be measured at a point 5cm away from the inverter.)
○ In case multiple inverters are installed
If multiple inverters are installed side-by-side, ambient temperature should be within
-10℃ to + 40℃ .
█
Install the inverter vertically.
Installing the inverter in any other way will decrease heat dissipation effect and result in malfunction.

Space for installation
● When a single inverter is installed
To ensure sufficient space for ventilation
(cooling) and wiring of the inverter, always
provide a clearance as shown in the
following figure.
● When multiple inverters are installed side-
by-side.
If multiple inverters are installed side-by-
side inside control panel, always provide a
clearance as shown in the following figure.
10 cm or more
