1.0 General information
General safety information
All safety hints contained in this section
and throughout the User Manual must
be complied with at all times to guarantee
the user's safety. The described product
must not be operated if any mechanical
or electrical components are defective.
Before commissioning the system, we
strongly advise you to carefully read and
heed the instructions! Non-compliance
can have serious consequences, for exam-
ple damage to the unit or other property
or physical injuries with possible loss of
life.
The solar inverter must be installed by a
trained, qualified electrician. The electrici-
an must be approved by the competent
electricity board (EB).
The relevant tasks to be carried out are
identified by an additional adjacent
symbol in the respective chapter headings.

1.1 Safety information
The User Manual contains safety hints.
These are identified by a triangle with an
exclamation mark.
!
Opening the unit
Before opening the cabinet, the unit must
always be disconnected from the grid and
from the PV generator.
The unit continues to conduct a hazardous
voltage internally and at the connection
sockets for ca. five minutes after disconnec-
ting from the PV generator. The energy
storage capacitors are only fully discharged
after this period.
After disconnecting the unit from the grid
and from the PV generator, you must wait
at least five minutes before opening the
unit.

Inspecting the delivery
The condition of our products is checked
prior to delivery. Although our products
are carefully packed in recyclable packing,
transportation damages can still occur.
These are generally the transport compa-
ny's responsibility.
Please inspect the delivered solar inverter
thoroughly!
If you discover any damage to the packing
or the solar inverter, please inform the
transport company immediately. Your
specialist dealer will be glad to assist you
if required. Any damages must always be
reported to the transport company in wri-
ting seven days after receipt of the goods
at the latest.
Integration of the solar inverter into the
PV system
Design of the PV generator
The technical data of the selected PV
generator must be within the specifica-
tion of the solar inverter (see Technical
Data). The Sunways NT Sundim design
program for the PV generator may be
helpful. Sunways NT Sundim is available
on the enclosed CD or from our web-
site, www.sunways.de.
Please take account of the following
points before planning your system:
· Pay attention to the skyward alignment
of the modules. You will obtain maxi-
mum yield in Central Europe with a
module inclination of 30° to the hori-
zontal and a direct southerly alignment
of the generator field.
· The output of the cells decreases as the
module temperature increases. Install
your PV generator with adequate rear
ventilation.
· Check your PV generator for soiling ca.
every three years. This occurs particularly
at the lower edge of the modules and
forms a film, which even heavy rain can-
not wash away. Decreases in yield can be
prevented by cleaning with a wet cloth
or a brush.
· Avoid shading of individual modules or
solar cells in your system. This can result
in heavy losses in yield.
