4. Close the unused holes in the cable gland using the locking pins.
5. Tighten the cable gland (wrench size: 34 mm).
6. Check the cable strain relief.
7. Close the inverter by fitting and tightening the cover.
You can now switch the inverter on as described in the instruction manual.
4�4�6 S0 interface
In accordance with DIN EN 62053-31 this interface (only available for the I/O module,
item no. 10 005 981) can be used to connect an energy counter to the inverter for the
purpose of the control self-consumption. From experience, SolarMax can recommend the
following electronic energy counters: Berg MCi32WP and Berg B23 311.
Connection conditions
■
■
Energy counters are only permitted with S0 pulses for feed-in (S0 pulses for both
directions of energy flow are not permitted).
■
■
The pulse rate of the energy meter must be between 1 000 and 10 000 pulses
per kWh.
