5. Installation

5.1 DC Connection (Battery)

Proper battery connection is crucial for safety and performance. Always ensure the inverter is turned off before proceeding.

1. Prepare the Inverter: Ensure the inverter's power switch is in the OFF position. Remove the protective covers and nuts from the DC input terminals (positive red, negative black) on the inverter.
2. Connect Positive Cable: Connect one end of the positive (red) battery cable to the inverter's positive terminal. Secure it tightly with the nut. Connect the other end of the positive cable to the positive terminal of your battery.
3. Connect Negative Cable: Connect one end of the negative (black) battery cable to the inverter's negative terminal. Secure it tightly with the nut. Connect the other end of the negative cable to the negative terminal of your battery.
4. Verify Polarity: Double-check that positive terminals are connected to positive and negative to negative. Reversing polarity will damage the inverter.
5. Pre-Charge Circuit (Recommended): For safe connection, especially with LiFePO4 batteries, use a pre-charge resistor to prevent sparks. Refer to your full manual for detailed instructions on installing a permanent pre-charge circuit.
6. Secure Connections: Ensure all connections are tight and secure. Replace the protective terminal covers.

5.2 AC Connection (Input/Output)

The inverter can be connected to an AC input source (grid or generator) and provides AC output for your loads.

1. Safety First: Turn off the mains power or generator before making any AC connections.
2. Access Terminal Block: Remove the protective cover from the AC wiring terminal block on the inverter.
3. AC Input Wiring: Use a 3-core AC cable (Live (L), Neutral (N), Ground (G)). Connect the Live (L) wire to the terminal labeled 'AC Input L', Neutral (N) to 'AC Input N', and Ground (G) to the grounding screw. This connection enables battery charging from the grid/generator and AC pass-through.
4. AC Output Wiring: Use another 3-core AC cable for your loads. Connect the Live (L) wire to 'AC Output L', Neutral (N) to 'AC Output N', and Ground (G) to the grounding point. This is where your home appliances or other loads will receive power.
5. Secure and Cover: Ensure all wires are securely fastened within their respective terminals. Replace the protective cover over the terminal block.

6. Operation
