2. MECHANICAL INSTALLATION. 2.1. POSITIONING THE DEVICE If you are installing the optional ESM3T EQX energy meter, we recommend installing the inverter as near to the electrical connection as possible, in order to avoid extending the RS485 communications cable. Angle and spacing of the installation: Make sure the device is installed on a vertical surface and that the following minimum safety distances are maintained with regard to other elements, in order to ensure optimum ventilation: Dimension...

Connect the cables to the inverter in accordance with the following connection diagrams: Connection process for facilities with solar parks of varying power (panels with different orientations and/or strings of different lengths): If the facility’s solar panels are not on the same level, i.e. they are exposed to different levels of radiation (whether due to the shape of the roof, differences in inclination, or different string lengths), the connection process must be carried out as follows: The devices allow for a maximum solar power imbalance of 40%-60%.
Make sure the protection systems in the junction box are activated and that there is no voltage in the cables you are going to handle. If you are installing the optional ESM3T EQX energy meter, we recommend installing the inverter as near to the electrical connection as possible, in order to avoid extending the RS485 communications cable.

Connecting the network cables: Unscrew the AC connector (supplied) and prepare the cables coming from the junction box of the power supply: Pass the cables through the screw cap, crown and rubber seal, as shown below. To optimise the connection, we recommend crimping the terminals at the ends of the cables.

Shut off the solar park power supply. Activate the protections in order to shut off the photovoltaic supply. Deactivate the inverter’s isolator switch and place it in the OFF position. The device will stop. When the internal capacitors of the DC bus are without voltage, the LCD screen will turn off. SALICRU...
5. OPERATION USING THE DISPLAY. 5.1. DISPLAY The buttons are operated by touch. Take care not to activate any functions accidentally. Button Symbol Function Exit the current mode. Go back to the previous menu. Access the Settings menu. Enter the chosen parameter. Confirm the value entered.
