2.3 Safety Precautions

Electric Shock

Lethal voltages are present in the conductive parts of the inverter.

• Prior to performing any work on the inverter, disconnect the inverter from any voltage sources

on the AC and DC sides (see inverter installation manual).

Burn Hazards

Some parts of the inverter enclosure can get hot during operation.

• During operation, touch the inverter on the enclosure lid only.

Electrostatic Discharge

By touching electronic components, you can damage or even destroy the inverter through electrostatic
discharge (ESD).

• Earth yourself before touching any inverter components.

Disturbance of Data Transmission due to AC Cables

During operation, AC cables generate an electromagnetic field which may induce interference in
plant communication.

• Lay the cables for RS485 communication using suitable fastening material and with a minimum

clearance of 50 mm to the AC cables.
