General information
1.1 Proper use
The PIKO inverter converts direct current into alternating
current. This can be used as follows:
n For self-consumption
n For feed-in into the public grid
The device may only be used in grid-connected photo-
voltaic systems within the permissible power range and
under the permissible ambient conditions. The device is
not intended for mobile use.
Inappropriate use can be hazardous and lead to injury
or even death to the user or third parties. Material dam-
age to the device and other equipment can also occur.
The inverter may therefore only be used for its intended
purpose.
All components fitted on the inverter or in the PV system
must satisfy the standards and guidelines that apply in
the country of installation.

General information
Exclusion of liability
Any use that diers from or goes beyond the stated
intended purpose is considered inappropriate. The
manufacturer accepts no liability for any damage result-
ing from this. Modifications to the inverter are prohibited.
The inverter may only be used if safe to operate and in
technically perfect condition. Any instance of misuse will
cause the termination of the warranty, guarantee and
general liability of the manufacturer.
Only a qualified electrician may open the device. The
inverter must be installed by a trained electrician (accord-
ing to DIN VDE 1000-10 or BGV A3 accident prevention
regulations) who is responsible for observing the applica-
ble standards and regulations.
Work that could aect the electrical power system of
the relevant energy supply company at the site of the
solar power feed-in may only be carried out by qualified
electricians expressly authorised (licensed) by the energy
supply company. This includes changes to the facto-
ry-preset parameters. The installer must always observe
the regulations of the energy supply company.
Factory settings may only be changed by qualified elec-
trical installers or persons with at least comparable or
higher technical qualifications, e.g. foremen, technicians
or engineers. When doing so, all requirements are to be
observed.
IMPORTANT
INFORMATION
The inverter may only be installed,
maintained and repaired by a
trained and qualified electrician.
The electrician is responsible for
ensuring that the applicable stand-
ards and regulations are observed
and implemented. Work that could
aect the electrical power system
of the relevant energy supply com-
pany at the site of the solar power
feed-in may only be carried out
by qualified electricians expressly
authorised (licensed) by the energy
supply company.
This includes changes to the
factory-preset parameters.
