Install on a vertical surface or structure capable of bearing the weight.

Please install the inverter vertically. If the inverter cannot be mounted vertically, it may be tilted backward to 15 degrees from vertical.

For multiple inverters are installed on site, a minimum clearance of 500mm,should be kept between each inverter and any other mounted equipment. The bottom of the inverter must be at least 500mm from the ground or floor. See figure 5.2.

Visibility of the LED status indicator lights and LCD display screen should be considered.
