5.3 Connecting the AC Output Power Cable

Precautions
A three-phase AC switch needs to be installed on the AC side of the SUN2000. To
ensure that the SUN2000 can safely disconnect itself from the power grid when an
exception occurs, select a proper overcurrent protection device in compliance with
local power distribution regulations.
Do not connect loads between the SUN2000 and the AC switch directly connected
to it.
The SUN2000 is integrated with a comprehensive residual current monitoring unit.
Once detecting that the residual current exceeds the threshold, the SUN2000
immediately disconnects itself from the power grid.
● If the external AC switch can perform earth leakage protection, the rated
● If multiple SUN2000s connect to the general residual current device (RCD)
● A knife switch cannot be used as an AC switch.
● The hex key is delivered with the inverter and bound to the hanging kit at the
Figure 5-4 Hex key
Procedure
Step 1 Connect the AC output power cable to the AC connector.

WARNING
NO TICE
leakage action current should be greater than or equal to 100 mA.
through their respective external AC switches, the rated leakage action current
of the general RCD should be greater than or equal to the number of
SUN2000s multiplied by 100 mA.
