● If an AC switch that can detect residual current is installed outside the SUN2000-50KTL-
M0, the residual current value to trigger the switch should be greater than 550 mA.
● 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.
NO TICE
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 SUN2000-50KTL/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.
– If you connect a ground cable to the ground point on the enclosure in a
scenario with a neutral wire, you are advised to use a four-core (L1, L2,
L3, and N) outdoor cable.
– If you connect a ground cable to the ground point in the maintenance
compartment in a scenario with a neutral wire, you are advised to use a
five-core (L1, L2, L3, N, 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.
– If you connect a ground cable to the ground point in the maintenance
compartment, you are advised to use a four-core (L1, L2, L3, and PE)
outdoor cable.
You need to prepare OT-M10 terminals that match the cables.
