User Manual 3.4 Space Requirement 3.5 Mounting Steps 1.Use the wall bracket as a template to mark the position of the 5holes on the wall. 2.Drill holes with driller, make sure the holes are deep enough (at least 75mm) for installation, and then tighten the expansion tubes.
User Manual Connection Steps 1. Choose the appropriate wire(Cable size: refer to Table3). 2.Remove 10mm of insulation from the end of wire. 3.Insert stripped wires into AC terminal and ensure that all conductor strands are captured in the AC terminal.Compress the terminal head by using a crimping pliers . 4.

User Manual SI 50K SI 60K SI 70K SI 80K ◆ Connecting the PV Array Danger to life due to lethal voltages! ◆ PV array supplies d.c voltage to inverter when exposed to light,before connecting the PV array, cover some light screens above PV arrays,ensure that the DC switch and AC breaker are disconnect from the inverter.
User Manual 4.3 485 Connection(Optional) ◆ 485 is provided the function of remote control that allows external control device to make the inverters remote cluster control through 485 port on the inverter. ◆ When routing the signal cable, ensure that it is separate from the power cable and away from interfering sources to prevent communication from being affected.
User Manual 4.4 Turn-off the Inverter Do not disconnect the DC connectors under load. Turn-off the inverter step: 1.Disconect the line circuit breaker from single-phases grid and prevent it from being reactivated. 2.Turn off the dc switch. 3.Check the inverter operating status. 4.Waiting until LED, OLED have go out, the inverter is shut down.
User Manual 7 Maintenance and Cleaning 7.1 Maintain Periodically 1.Checking Heat Dissipation If the inverter regularly reduces its output power due to high temperature, please improve the heat dissipation condition. Maybe you need to clean the heat sink. 2. Cleaning the Inverter If the inverter is dirty, turn-off the AC breaker and DC switch ,waiting the inverter shut down ,then clean the enclosure lid, the display, and the LEDs using only a wet cloth.
