2.3.6 Risk of death due to inadequate fastening
of the collectors
Collectors can fall from their anchors if they are not prop-
erly fastened on the roof. Collectors falling from the roof
could cause life-threatening accidents.
▶ Perform all work steps as described in this manual.
▶ Observe all safety precautions described in this manual.
▶ In addition, comply with all safety regulations that spe-
cifically apply in your region.
2.3.7 Risk of burns due to hot collector surfaces
In the event of solar radiation inside the units, collectors
can reach 300 °C. If you touch the collectors without pro-
tection, you could burn yourself.
▶ Remove the sun protection film installed at the factory
only after the solar plant has been started up.
▶ Avoid performing installation and maintenance work
under direct sunlight.
▶ Cover the collectors before starting work.
▶
You should preferably perform the work in the morning.
▶ Wear suitable safety gloves.
2.3.8 Risk of injury due to breaking glass
The glass of the collectors may break due to mechanical
destruction or torsion.
▶ Wear suitable safety gloves.
▶ Wear suitable protective goggles.
2.3.9 Material damage caused by a high-pressure
cleaner
High-pressure cleaners may damage the collectors due to
the extremely high pressure.
▶ Never clean the collectors with a high-pressure cleaner.
2.3.10 Material damage due to lightning
Lightning can damage the collector system.
▶ Connect the collector system to a lightning protection
device in accordance with applicable regulations.
2.3.11 Frost damage due to water in the solar
circuit
Water residue in the collector may freeze in frosty condi-
tions and damage the collector.
▶ Never fill or flush the collector with water.

In particular, only use the tool specified in the work steps
of this manual.
2.3.13 Risk of death from electric shock
Incorrect installation or a faulty power cable can result in a
supply voltage on the pipes, which can cause life-threaten-
ing injuries.
▶ Secure earthing pipe clamps to the pipes.
▶ Connect the earthing pipe clamps to a busbar using 16
mm
²
copper cable.
2.3.14 Material damage due to overvoltage
Overvoltage may damage the solar plant.
▶ Earth the solar circuit to provide equipotential bonding
and overvoltage protection.
▶ Secure earthing pipe clamps to the pipes.
▶ Bond the earthing pipe clamps to a busbar using 16 mm
²
copper cable.
2.3.15 Risk of death and material damage due to
contact corrosion
For roofs or façade sections made of metals more precious
than aluminium (e.g. copper roof), contact corrosion may
occur on the brackets. Collectors could fall and put persons
at risk.
▶ Use suitable underlays to separate the metals.
2.3.16 Material damage due to snow falling from
roofs
If the collector field is installed below a sloping roof, then
snow falling from the roof may damage the collectors.
▶ Install snow fences above the collectors as protection
against falling snow.
