According to IEC62109, to ensure the safe operation of the SUN2000 in the case of PE cable
damage or disconnection, connect the SUN2000 PE cable according to the requirements described in
5.2 Installing the PE Cable and ensure that the SUN2000 PE cable meets at least one of the
following requirements before disabling the grounding detection function.
The SUN2000 PE cable is a copper cable with a cross-sectional area of at least 10 mm
2
.
Use two cables that have the same diameter as the AC output power cable to ground the PE terminal
on the AC connector and the ground screw on the enclosure respectively (see 5.2 Installing the PE
Cable and 5.3 Installing the AC Output Power Cable for details).
Certain countries require an additional PE cable for the SUN2000. In this case, use two cables that
have the same diameter as the AC output power cable to ground the PE terminal on the AC
connector and the ground screw on the enclosure respectively (see 5.2 Installing the PE Cable and
5.3 Installing the AC Output Power Cable for details).
Procedure
Step 1 Connect the AC output power cable to the AC connector.
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 firm 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.
