5 Cable Connection

5.1 Connect Cables to the AC Grid Side and off - Grid Side
RX-2505PW has terminals for on and off-grid. As shown in Figure 5-1, the left terminal is the off-grid
terminal (EPS) and the right terminal is the on-grid terminal. An independent AC circuit breaker must
be configured for each circuit to safely disconnect then system. When selecting the external cable,
consider the hole in the cable gland.The table below is a recommendation for cable selection.
Engineers should refer to local standards to select cables. Cable length is generally 2 to 10 meters,
long cable will lead to voltage drop from the rated value, consequently requiring an increase of the
cross-sectional area.
