–
Do not touch the electrical connections.
–
Remove all jewellery from your wrists and fi ngers.
– Ensure that the testing equipment is in safe operating condition.
• Stand on an insulated surface when working on the inverter.
• Modifi cations to the surroundings of the inverter must comply with the applicable national and local standards.
• When working on the PV generator, it is also necessary to switch off the DC voltage with the DC isolator switch in
addition to disconnecting the PV generator from the grid.
2.1 Proper use
The inverter converts the DC voltage generated by the PV modules into AC voltage and feeds it into the grid. The
inverter is built according to the latest technological standards and safety regulations. Nevertheless, improper use
may cause lethal hazards for the operator or third parties, or may result in damage to the unit and other property.
Operate the inverter only with a permanent connection to the public power grid.
Any other or additional use of the device shall be regarded as improper. This includes:
• Mobile use,
• Use in potentially explosive atmospheres,
• Use in rooms where the humidity is higher than 95%
• Operation outside the specifi cations intended by the manufacturer,
• Islanding operation.
2.2 Protection features
The following monitoring and protective functions are integrated into KACO inverters:
• Overvoltage conductors/varistors to protect the power semiconductors from high-energy transients on the grid
and generator side
• Temperature monitoring of the semiconductor (cooling body)
• EMC fi lters to protect the inverter from high-frequency grid interference
• Grid-side grounded varistors to protect the inverter against burst and surge pulses
• Islanding detection according to the current standards.
2.3 Trademark
The software of the inverter uses the MD5 Message Digest algorithm of RSA Data Security, Inc.
The devices uses the open source operating system FreeRTOS 7.00
