NO TICE
● 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.
NO TICE
● The PE point at the AC output port is used only as a PE equipotential point, and
cannot substitute for the PE point on the enclosure.
● Keep the AC output power cable and the PE cable close to each other.
● Keep the AC output power cable and the DC input power cable close to each
other.
● Ensure that the cable jacket is inside the connector.
● Ensure that the exposed core is totally inserted into the cable hole.
● Ensure that AC output cable is secured. Failing to do so may cause SUN2000
malfunction or damage to its AC connector.
● Ensure that the cable is not twisted.
