Important notes
DANGER!
Dangerous electrical voltage
During oper
aon and up to 20 minutes aer power-o, hazardous electrical voltages may be
present at the connecons of the product.
The leakage current against earth (PE) is > 3.5 mA AC or > 10 mA DC.
Possible consequences: Death or serious injury from electric shock
Protecve measures
▶
Any work on the product must only be carried out in a deenergized state.
▶
Check that no voltage is present!
▶
Aer switching o the mains voltage, observe the signs on the product.
▶
Aer switching o, wait unl the drive comes to a standsll.
▶
Implement the measures required by EN 61800‑5‑1 or EN 60204‑1, i.e. xed installaon and
standard-compliant PE connecon.
DANGER!
Use of the inverter on a phase earthed mains with a rated mains voltage ≥ 400 V
The pr
otecon against accidental contact is not ensured without external measures.
▶
If protecon against accidental contact according to EN 61800‑5‑1 is required for the
control terminals of the inverters and the connecons of the plugged device modules, ...
▶
an addional basic insulaon has to be provided.
▶
the components to be connected have to come with a second basic insulaon.
WARNING!
Dangerous electrical voltage
De
vice 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
No pr
otecon against excessively high mains voltage
The mains input is not fused internally.
Possible consequences: Destrucon of the product in the event of excessively high mains
voltage.
▶
Take note of the maximum permissible mains voltage.
▶
On the mains supply side, use fuses to adequately protect the product against mains
uctuaons and voltage peaks.
