Important notes
DANGER!
Electrical voltage
Possible consequences: Death or severe injuries
▶
Any work on the inverter must only be carried out in the de-energized state.
▶
Inverter up to 45 kW: Aer switching o the mains voltage, wait for at least 3 min before you start
working.
▶
Inverter from 55 kW onwards: Aer switching o the mains voltage, wait for at least 10 min before you
start working.
DANGER!
Dangerous electrical voltage
The leakage current against earth (PE) is > 3.5 mA AC or > 10 mA DC.
Possible consequences: Death or severe injuries when touching the device in the event of an error.
▶
Implement the measures requested in EN 61800−5−1 or EN 60204−1. Especially:
▶
Fixed installaon
▶
The PE connecon must comply with the standards (PE conductor diameter ≥ 10 mm
2
or use a double PE
conductor)
WARNING!
Dangerous electrical voltage
Device error causes an overvoltage in the system.
▶
For a voltage supply with DC 24 V (± 20 %), use only a safely separated power supply unit according to the
valid SELV/PELV requirements.
NOTICE
Mounng not according to protecon class
Possible consequences: Material damage due to penetrang humidity and foreign bodies.
▶
All cable glands and mounng parts must at least correspond to the protecon class of the inverter.
▶
All openings in the housing must be closed according to the protecon class.
▶
The cover must be screwed on with the specied ghtening torque.
