General Notes
1.4 Safety instructions
DANGER
Lethal voltages are still present in the terminals and lines of the inverter even after
the inverter has been switched off and disconnected!
Coming into contact with the lines and terminals in the inverter will cause serious
injury or death.
Only authorised electricians who are approved by the supply grid operator are allowed
to open, install and maintain the inverter.
› Keep all doors and covers closed when the unit is in operation.
› Do not touch the lines and terminals when switching the unit on and off!
WARNING
Lethal voltage in the PV system
When the photovoltaic array is exposed to light, it supplies a d.c. voltage to the
inverter.
The electrician is responsible for observing all existing standards and regulations.
• Above all, be sure to observe standard IEC 60364-7-712:2002, “Requirements for Special Installations or
Locations – Solar Photovoltaic (PV) Power Supply Systems”.
• Be sure to be responsible for knowing and understanding local standards and regulations as well as utility
interconnection requirements.
• Ensure operational safety by providing for proper earthing, conductor dimensioning and appropriate protec-
tion against short circuiting.
• Observe the safety instructions located on the inner sides of the doors.
• Switch off all voltage sources and secure them against being inadvertently switched back on before perform-
ing visual inspections and maintenance.
• When taking measurements while the inverter is live:
- Do not touch the electrical connections.
- Remove jewelry from your wrists and fingers.
- Make sure that the testing equipment is in good and safe operating condition.
• Stand on an insulated surface when working on the inverter.
• Performing any modifications or changes on the inverter is generally prohibited. Performing any changes or
modifications to the installation of the inverter is only permitted if in compliance with national standards and
performed by qualified personnel.
• Modifications to the surroundings of the inverter must comply with national and local standards
