2.2 Skills of Qualified Persons
The activities described in this document must only be performed by qualified persons. Qualified
persons must have the following skills:
• Training in the installation and commissioning of electrical devices and installations
• Knowledge of how to deal with the dangers and risks associated with installing and using
electrical devices and installations
• Knowledge of all applicable standards and directives
• Knowledge of how an inverter works and is operated
• Knowledge of and compliance with this document and all safety information
2.3 Safety Information
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 all 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, do not touch any parts other than the enclosure lid of the inverter.
Electrostatic Discharge
By touching electronic components, you can damage or even destroy the inverter through electrostatic
discharge (ESD).
• Ground yourself before touching any inverter component.
Interference in Data Transmission due to AC Cables
During operation, AC cables generate an electromagnetic field which may induce interference in
plant communication.
• Lay the RS485 communication cables using suitable fastening material and with a minimum
clearance of 50 mm to the AC cables.
