Installing the AC Output Power Cable
4.3
• Ensure that the exposed core wire is completely inserted into the cable hole and connected
securely. Failing to do so may cause the SUN2000 to malfunction or be damaged.
• If the AC output power cable bears pulling force because the inverter is not installed securely,
ensure that the last cable that bears the force is the PE cable.
• In the following figure, 1.0 mm x 5.5 mm (0.04 in. x 0.22 in.) is the thickness and width of the
screwdriver blade.
