2. Connecting to Battery:

   Use the provided battery cables. Connect the red cable to the positive (+) terminal of the inverter and the positive (+) terminal of your 12V battery. Connect the black cable to the negative (-) terminal of the inverter and the negative (-) terminal of your 12V battery. Ensure connections are tight and secure.
3. Grounding the Inverter:

   Connect the inverter's grounding terminal to a proper earth ground. This helps absorb interference and ensures stability and reliability.

4. Connecting the Remote Control:

   Plug the remote control cable into the designated port on the inverter. The remote control allows for convenient operation and monitoring from a distance.

5. Adjusting Input Voltage (if necessary):

   If using lithium batteries or requiring specific low voltage shutdown settings, adjust the input voltage function (9.5V-11V) using the switches on the inverter. Important: This adjustment must be made when the inverter is turned OFF.
