under abnormal conditions, select an appropriate overcurrent protection device
according to local power distribution regulations.
Model
SUN2000-60KTL-M0
SUN2000-65KTL-M0
Do not connect loads between the SUN2000 and the AC switch.
The SUN2000 is integrated with a comprehensive residual current monitoring unit
(RCMU) to distinguish fault current from residual current. Upon detecting that the
residual current exceeds the threshold, the SUN2000 immediately disconnects
from the power grid.

● If an AC switch that can detect residual current is installed outside the SUN2000-60KTL-
M0, the residual current value to trigger the switch should be greater than 660 mA.
● If an AC switch that can detect residual current is installed outside the SUN2000-65KTL-
M0, the residual current value to trigger the switch should be greater than 720 mA.
The ground point on the enclosure is preferred to connect to the PE cable for
the SUN2000.
The ground point in the maintenance compartment is mainly used for
connecting to the ground cable included in the multi-core AC power cable.
There are two ground points on the enclosure and you only need either of
them.
It is recommended that the ground cable be connected to a nearby ground
point. For a system with multiple SUN2000s connected in parallel, connect the
ground points of all SUN2000s to ensure equipotential connections to ground
cables.
For the SUN2000-60KTL-M0:
– If you connect a ground cable to the ground point on the enclosure in a
scenario with no neutral wire, you are advised to use a three-core (L1, L2,
and L3) outdoor cable.
– If you connect a ground cable to the ground point in the maintenance
compartment in a scenario with no neutral wire, you are advised to use a
four-core (L1, L2, L3, and PE) outdoor cable.
For the SUN2000-65KTL-M0:
– If you connect a ground cable to the ground point on the enclosure, you
are advised to use a three-core (L1, L2, and L3) outdoor cable.
