Operating manual
8 Help in the case of faults
Possible fault rectification
| Check solar power system
field for earth leakage
| Check the idling voltage of the
solar power system field
| If the fault continues, contact
the manufacturer's service
centre (contact information on
the back of the manual).
| Check solar power system
field for earth leakage
| Wait for improvement in the
weather
| Check the voltage of the solar
power system field
| Check solar power system for
earth leakage
| Check installation and con-
nector pin assignment (see
chapter 5.2, page 30)
| Check grid type (see
chapter 3.7, page 19)
| Check installation and con-
nector pin assignment (see
chapter 5.2, page 30)
| Check grid type (see
chapter 3.7, page 19)
| Check installation and con-
nector pin assignment (see
chapter 5.2, page 30)
| Check power cable
| Check line frequency
| Check installation and con-
nector pin assignment (see
chapter 5.2, page 30)
| Check AC fuse
