or companies (like AS 4777 and AS/NZS 3000 in Australia).
Before any wiring connection or electrical operation on inverter, all battery and
AC power must be disconnected from inverter for at least 5 minutes to make sure
inverter is totally isolated to avoid electric.
The temperature of inverter surface might exceed 60℃during working, so please
make sure it is cooled down before touching it, and make sure the inverter is
untouchable for children.
Usage and operation of the inverter must follow instructions in this user manual,
otherwise the protection design might be useless and warranty for the inverter will be
invalid.
Do not open inverter cover or change any components without authorization, otherwise
the warranty commitment for the inverter will be invalid.
Appropriate methods must be adopted to protect inverter from static damage. Any
damage caused by static is not warranted by eCactus.
The inverter, with built-in RCMU, will exclude possibility of DC residual current to
6mA, thus in the system an external RCD (type A) can be used(≥30mA).
In Australia, output of backup side in switch box should be labeled ‘Main switch UPS
supply’, the output of normal load side in switch box should be labeled ‘main switch
inverter supply’.
