6.2.1 Connecting the AC Output

A round plug connector system is used, which allows various cable diameters to be

used in the cable outlet. For this reason, the accessories kit includes a PG13.5 pressure

screw and a PG16 pressure screw. Check which screw fitting is the right one for your

AC cable.

To connect up the AC output, follow these steps:

1. Check the grid voltage. If this is higher than 253 V, the Sunny Boy will not be fully

operational. In this case, contact the local grid operator for assistance.

2. Isolate the grid connection (switch the line circuit

breaker to its "off" position), make sure it cannot

be switched back on, and test to make sure no

voltage is present.

3. Peel off approximately 30 mm of the cable

jacket. Shorten L and N by 5 mm.

4. Strip approximately 4 mm of the cable's

insulation.

Warning! Voltage!

Before you connect the mains cable to the AC connection socket, make

sure that no voltage is present at the cable.

Off!
