Electric arcs form when electrical connections
are made or disconnected incorrectly.
Severe or fatal injuries from electric shock or
severe injury from burns!
• Before you carry out any work on electrical compo-
nents, disconnect the photovoltaic generator.
Contact with live parts due to defective insulation
or damaged/fallen off junction box covers.
Severe or fatal injuries from electric shock!
• Do not touch damaged parts with your bare hands.
• Use protective clothing and suitable, insulated tools.
High DC voltages, even when the photovoltaic
generator is disconnected if the generator is
earthed.
Severe or fatal injuries from electric shock!
• If the circuit of your photovoltaic generator is
earthed, remove the earth before you carry out
electrical work on the generator.
GEFAHR!
WARNING!
Contact with live parts due to unsuitable tools
or weather conditions. Risk of electric shock!
• Only use approved, insulated tools for maintenance
work on live parts.
• Work in dry conditions. Ensure that the electrical
connections of the solar module, the cables and the
tools are dry.!
RECOMMENDATION
Work in pairs so that in an emergency one person is
able to help in the case of injury. This is because the
PV modules generate voltage as soon as they are ex-
posed to light. Therefore, parts of the system are
nearly always energised during the daytime.
3.2.2 Mechanical safety precautions
WARNING!
Glass can crack, break or splinter. Beware
of injury!
• Never step or sit on PV modules.
• Avoid knocking and bumping the surface,
the edges and corners of the glass panels.
WARNING!
Exposed live parts due to damaged glass.
Risk of electric shock!
• Only use PV modules with the insulation in
perfect condition.
CAUTION!
Sharp glass edges or flying glass splin-
ters. Beware of injury!
• Always use suitable protective equipment
(e.g. gloves and goggles).
• Be especially careful with the glass edges
and corners of laminates (frameless mod-
ules).
• Insulating back sheet
WARNING!
Damaged insulating back sheet. Risk of
electric shock and burns!
• Avoid any contact with the back of the mod-
ule with sharp or pointed objects.
• Ensure the back sheet remains undamaged.
4 Preparing for installation
4.1 Handling PV modules
4.1.1 Storing PV modules
■ PV Modules in packing units :
WEIS
• For PV modules packed in vertical position:
Store the PV modules upright in the packaging
units. Make sure that each module has sufficient
support.
• For PV modules packed in horizontal position:
Store the PV modules flat in the packaging
units.
• Do not stack the packaging units. This could damage
the PV modules.
■ Individual PV modules:
• Store individual PV modules in an upright position
on wedges with suitable padding. Use adequate pad-
ding between the individual PV modules.
• Avoid stacking individual PV modules, as well as the
pallets they rest on.
