Grid and Backup Connection
The steps for connecting the grid and backup connector as follows:
1. Disconnect the circuit breakers and secure it against reconnection.
2. Dismantle the AC cable by 50 mm.
3. Shorten L and N by 5 mm each, so that the grounding conductor is 5 mm longer.
This ensures that the grounding conductor is the last to be pulled from the screw
terminal in the event of tensile strain.
4. Strip the insulation of L, N and the grounding conductor 10 mm.
5. In the case of fine stranded wire L, N and PE are to be fitted with bootlace ferrules.
6. Disassemble the AC connector and connect the conductors to the AC connector.
7. Ensure that all conductors are securely connected to the AC connector, assemble the
AC connector.
8. Plug the AC connector into the socket for the AC connection.
When doing so, align the AC connector so that the key on the SMILE5-INV AC socket
is inserted into the keyway on the AC connector bush insert.
For grid connector, still need to turn the grid connector slightly clockwise until you
hear a "click" sound.
