AC Circuit Breaker and DC Disconnect Switch
The circuit breaker populated on the distribution board varies depending on the installer.
Follow the installation standards to install a circuit breaker satisfying the voltage, the current
specification of the Grid and the PV. The cables presented in the [Table 5-5] are
recommended for use.

[Table 5-5: Circuit breaker, DC Disconnection Switch and power line specification]
As illustrated in the [Figure 5-17], the distribution box connection diagram, the connection
between the All in One system and the distribution box is made to the terminals of the solar
energy (,PVdso1-,, and PVdso2-) of PV1+, PV1-, PV2+, and PV2-.
On one hand, the main body terminals (PV1 +, PV1 -, PV2+, PV2-) and the distribution box
terminals are connected in proper order. On the other hand, for the lines coming from the
AC GRID, L and N leads are connected to the distribution board (LG, NG). The lines coming
out from the LGO, PGO of the distribution board are be connected to the L and N terminals
of the All in One System.
5.7.2
RCD (residual current device) Leakage Circuit Breaker
This product can cause a DC current in the external protective earthling conductor. Where a
residual current-operated protective (RCD) or monitoring (RCM) device is used for protection
in case of direct or indirect contact, either an RCD or RCM of Type A or Type AC is only
available on the supply side of this product.
