1.1 Unpacking and Inspection

Before installation, please inspect the unit. Be sure that nothing inside the package is damaged.

You should have received the following items inside of package:

The unit x 1 User manual x 1 DC Fuse x 1 Ring terminal x 1 Strain relief plate x 1 PV wire cover x 1 Screws x 4 Dust cover x 1

1.2 Preparation

Before connecting all wirings, please take off bottom cover by removing four screws as shown below.

A Notice:Slowly remove wire cover.There is a communication cable connect to the main board

1.1 Mounting the Unit

Consider the following points before selecting where to install: Do not mount the inverter on flammable construction materials.Mount on a solid surface Install this inverter at eye level in order to allow the LCD display to be read at all times.3S For proper air circulation to dissipate heat, allow a clearance of approx. 20 cm to the side and approx. 50 cm above and below the unit.The ambient temperature should be between 0°C and 55°C to ensure optimal operation.The recommended installation position is to be adhered to the wall vertically.Be sure to keep other objects and surfaces as shown in the diagram to guarantee sufficient heat dissipation and to have enough space for removing wires.
