General Notes
1.3 Intended use
The inverter converts the DC voltage generated by the photovoltaic (PV) modules into AC voltage and feeds this
into the power grid. The inverter is built according to the state of the art and recognized safety rules. Neverthe-
less, improper use may cause lethal hazards for the operator or third parties, or may result in damage to the
unit and other property. The inverter may be operated only with a permanent connection to the public power
grid.
Any other or additional use is not considered the intended use. Examples of unintended use include:
• Mobile use
• Use in rooms where there is a risk of explosion
• Use in rooms where the humidity is higher than 95%
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!
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”.
• Ensure operational safety by providing for proper earthing, conductor dimensioning and appropriate
protection 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 per-
forming 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.
• Generally, the inverter may not be modified.
• Modifications to the surroundings of the inverter must comply with national and local standards.
