2.3 Basic safety measures
Electrical work on the solar inverter must
be conducted by a qualified electrician
while observing the VDE regulations,
national and other regulations!

When circuit breakers are tripped, the
fault cause must be determined and
eliminated before returning the unit to
operation.
Check electrical equipment regularly!
Retighten loose connections!
Replace damaged lines/cables
immediately!

The following parameters are monitored
and displayed continuously and simulta-
neously by the inverter controller:
· DC overvoltage
· Overvoltage L1 > 10%
· Overvoltage L1 > 15%
· Undervoltage L1
· Overvoltage L2
· Undervoltage L2
· Overvoltage L3
· Undervoltage L3
· Isolated operation
· Overfrequency L1
· Underfrequency L1
· Surge error (brief overvoltage L1)
· DC share in AC current
· AFI residual current jump > 30 mA
· AFI residual current > 300 mA
· Overtemperature of heat sink
