NO TE
● 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.
Wiring Precautions
NO TICE
Ensure that the SUN2000 PE cable is securely connected.
● 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.
Cable Specications
● 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
ve-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.
