Important notes

DANGER!
Danger to life due to electric shock!
Death or serious injuries
▶ Deenergize the inverter before working on the inverter.
▶ Inverter up to 45 kW (60 hp): After switching off the mains voltage, wait for at least 5 minutes before you
start working.
▶ Inverter from 55 kW (75 hp): After switching off the mains voltage, wait for at least 20 minutes 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
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.
EMC-compliant installation
The drive system (inverter and drive) only complies with the EMC Directive 2014/30/EU if it is installed
according to the guidelines for CE-typical drive systems.
These guidelines should also be followed in installations requiring FCC Part 15 or ICES 001 compliance.
EMC-compliant installation in the control cabinet must be implemented with shielded motor cables of low
capacity.
Capacitance per unit length:
• C-core-core/C-core-shielding: < 75/150 pF/m ≤ 2.5 mm² (≥ AWG 14);
• C-core-core/C-core-shielding: < 150/300 pF/m ≥ 4 mm² (≤ AWG 12)
