Requirements
☐ The medium-voltage switchgear is switched off.
☐ The low-voltage switchgear is switched off.
☐ All terminals have been connected as per the instructions and the circuit diagram (see section
7 "Electrical Connection", page 17).
1. Inspect the cabling to the Transformer Compact Station (see section 8.2).
2. Make sure the temperature settings on the Hermetic transformer protection unit are correct:
– Warning temperature: 90°C
– Actuation temperature: 100°C
5. Check the low AC voltage in the low-voltage switchgear (see section 8.3).
6. If you have an internal power supply transformer: Connect the internal power supply for the
Transformer Compact Station (see section 8.4).
7. Turn on the power supply to the Transformer Compact Station with the "main circuit breaker".
8. Turn on the station lighting with the "voltage supply lighting" miniature circuit-breaker.
9. Energize the earthed outlet with the "voltage supply power outlet" miniature circuit-breaker with
the integrated residual current device.
10. Turn on the fan with the "voltage supply fan motor" miniature circuit-breaker.
11. Turn on the GSE meter with the "voltage supply feed-in meter" miniature circuit-breaker.
12. Turn on Communit with the "voltage supply Communit" miniature circuit-breaker.
13. Turn on low-voltage switchgear (see the documentation for the low-voltage switchgear).
14. Connect the internal power supply for the inverter (see section 8.5).
15. Commission the inverter (see the inverter documentation).
3.
Only a duly authorized person trained in electrical safety can connect the AC
voltage of the medium-voltage transformer.
Have the AC voltage of the medium-voltage transformer connected externally.
4.
Only a duly authorized person trained in electrical safety can switch on the
medium-voltage switchgear.
Have the medium-voltage switchgear switched on (see the documentation for the
medium-voltage switchgear).
