ment is well-ventilated.
When installing the cabinet, be sure to leave enough space around the inverter for heat
dissipation; do not place the inverter and the lead-acid liquid battery together.
False connection points and corroded wires can cause extreme heat to melt wire insulation,
burn surrounding materials, and even cause fire, so make sure that the connectors are
tightened, and the wires are fixed by cable ties to avoid loose connectors caused by shaking of
the wires during mobile applications.

With a 3rd position boat switch, the inverter has 3 operating modes including OFF, ON, and ECO
when the external switch contact is closed.
5 External switch contact interface
2P switch interface: Inverter can work when the interface is short-circuited; Inverter fails to work
when the interface is open. The interface can be connected to a mechanical switch or relay to
control the inverter to start/stop (this application requires keeping the mode switch in the ON or
ECO mode position) in practical application.
Switch position
Remark: When using an APP or other communication devices to switch the working mode,
the current actual working mode will be inconsistent with the boat switch position. The
working mode of the inverter is based on the last adjusted position at the APP or communi-
cation device or the boat switch.
