Instructions to prevent deep discharged battery

To prevent deep discharged battery, when the RESU battery is not in use after installation, please turn off the Circuit

Breaker(CB) first and then be sure to turn the AUX POWER switch off afterwards. Even if the Circuit

Breaker(CB) is automatically tripped, the AUX POWER switch must be turned off manually.

Also, ensure that the battery must be installed and operated within six months of the date of production.

Please follow the procedure below to prevent deep discharged battery. We recommend contacting your certified RESU
