4. Ensure that the strands are connected properly.
5. Snap the rear part of the socket onto the socket insert.
6. Tighten the screwed cable gland.
Connecting the AC feed line
The AC feed line can now be connected to the AC connection of the inverter. As soon as
the correct position is reached, the connector slips onto the AC connection.
The inverter is now  rmly connected to the AC grid.
NOTE
As soon as the closure of the AC connector has slipped in, the AC connection can only
be re-opened using a tool (slotted screwdriver size 2).
4.7.7 Connecting the inverters to the PV plant
You can connect as many as three strings directly to the inverter.
DANGER
Make sure that all the DC and AC feed lines to the inverter are dead before you start
the installation work.
Connecting conditions
■ Maximum DC input current SM2000S and SM3000S: 11 A
■ Maximum DC input current SM4200S and SM6000S: 22 A
■ Maximum DC input voltage (SM2000S-SM6000S): 600 V
■ Select cable cross-sections on the DC end corresponding to your plant con guration
and in conformance with the valid installation regulations.
■ Ensure that the DC cable is installed so as to avoid short-circuits and earth leakage all
the way to the MC connections.
■ Use only connectors from the MC4 series made by MultiContact for connecting the DC
feed lines to the inverters.
■ Due to the earth leakage monitoring neither the minus nor the plus pole may be earthed.
Otherwise, the integrated insulation monitoring will prevent a mains connection.
