6.4 Connecting the mains cable
Each inverter of the Conergy IPG string inverter series has a
5-pole AC out socket (see Fig. 6-1, page 35, pos. (3)) for the
connection to the grid. Use a PZ1 screwdriver and tighten the
screws to 0.5–1 Nm. The mains cable must have a cable
section of 4 mm

.
For devices with AC output of up to 4.6 kW a single string
inverter of the Conergy IPG series is used. For the operation
of systems with higher outputs, several string inverters are
used. These are to be connected so that they are distributed
over several phases. The wiring of several string inverters is
shown in the following diagram.
Do not connect any consumers between the Conergy IPG
string inverter series inverter and the utility's meter. The
consumers will otherwise be supplied with electricity which is
not paid for by the utility.
