Important notes

DANGER!
Electrical voltage
Possible consequences: Death or severe injuries
▶ Any work on the inverter must only be carried out in the deenergised state.
▶ Inverter up to 45 kW: After switching off the mains voltage, wait for at least 180 s before
you start working.
▶ Inverter from 55 kW onwards: After switching off the mains voltage, wait for at least 600 s
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 installation
▶ The PE connection must comply with the standards (PE conductor diameter ≥ 10 mm
use a double PE conductor)
NOTICE
No protection against excessively high mains voltage
The mains input is not fused internally.
Possible consequences: Destruction of the product in the event of excessively high mains volt-
age.
▶ Take note of the maximum permissible mains voltage.
▶ On the mains supply side, use fuses to adequately protect the product against mains fluctu-
ations and voltage peaks.
DANGER!
Use of the inverter on a phase earthed mains with a rated mains voltage ≥ 400 V
The protection against accidental contact is not ensured without external measures.
▶ If protection against accidental contact according to EN 61800-5-1 is required for the control
terminals of the inverters and the connections of the plugged device modules, ...
▶ an additional basic insulation has to be provided.
▶ the components to be connected have to come with a second basic insulation.
