● If the external AC switch can perform earth leakage protection, the rated
leakage action current should be greater than or equal to 100 mA.
● If multiple SUN2000s connect to the general residual current device (RCD)
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.
● A knife switch cannot be used as an AC switch.
Procedure
Step 1 Connect the AC output power cable to the AC connector.
Figure 5-4 Stripping requirements
● Ensure that the cable jacket is inside the connector.
● Ensure that the exposed core wire is totally inserted into the cable hole.
● Ensure that AC terminations provide rm and solid electrical connections.
Failing to do so may cause SUN2000 malfunction and damage to its AC
connectors.
● Ensure that the cable is not twisted.
Strip the insulation layers of the AC output power cable by the recommended
length (12–16 mm) to ensure that the cable conductors are completely inside the
conductor insertion points and no insulation layer is pressed into the conductor
insertion points. Otherwise, the device may fail to run properly or be damaged
during operation.
