Proven quality – simply clever
With the for solar power systems, you have purchased a high-quality product from the SolarWorld
AG product range.
To ensure that the solar power system runs smoothly, all components selected and used in the mounting system
are of the highest quality. The following instructions describe the correct installation of the based
on an example. This should help you to easily install the mounting system. The appearance of special structural
features must be documented so that the unique features of the roof can be considered in the system planning.

A2 Safety instructions
DANGER!
Danger of death from electric shock
fSolar modules generate electricity as soon as they
are exposed to light. The voltage of a single modu-
le is lower than 50 V direct current (DC). When
several modules are connected in series, the total
voltages are cumulative and dangerous. When
several modules are connected in parallel, the cur-
rents are cumulative. Although touch protection
is provided in the form of the fully insulated plug
contacts, the following points must be observed
when handling the solar modules to avoid the risk
of fire, sparking and dangerous electric shock:
fDo not install solar modules and wiring using wet
plugs and sockets!
fUtmost caution must be exercised during all work
on the wiring!
fThe inverter can produce high touch voltages,
even when not connected!
fExercise caution during all work on the inverter
and wiring!
DANGER!
Danger of death from arcing
fModules generate direct current (DC) when light
strikes them. When breaking a connected string
of modules (e.g. when disconnecting the DC line
from the inverter under load), a dangerously
strong arc can occur. Note the following:
fNever remove the solar generator from the inver-
ter while it is still connected to the grid.
fEnsure that the cable connections are in perfect
condition (no gap, soiling)!
WARNING!
Danger of falling
fThere is a risk of falling when working on the roof
and when climbing up and down. You must obser-
ve the accident prevention guidelines and use
suitable fall protection equipment.
WARNING!
Flammable materials
fModules must not be operated near equipment or
in locations where flammable gases or dusts are
emitted or can collect.
CAUTION!
Hand injuries
fHands can be crushed during the installation of
support frames and modules.
fWork may only be carried out by trained sta.
fUse protective gloves!
CAUTION!
Falling objects
fWhen mounting on the roof, there is a risk of tools,
mounting materials or modules falling from the
roof and injuring persons who are present below.
fCordon o the danger area on the ground before
starting installation work, and warn persons in the
vicinity.
