A2 Safety information
DANGER!
Risk of fatal arcing
fSolar modules generate direct current (DC) when
exposed to light. Breaking a connected string of
modules (e.g., when disconnecting the DC line
from the inverter under load) may result in dange-
rous arcing. Observe the following:
fNever disconnect the solar generator from the
inverter while the inverter is still connected to the
power grid.
fEnsure that the wire connections are in perfect
condition (no cracking, no soiling)!
WARNING!
Risk of falling
fRisk of falling when working on the roof and when
climbing up and down. Observe accident preven-
tion regulations and use suitable fall protection
equipment under all circumstances.
WARNING!
Flammable materials
fSolar modules must not be operated in the vicinity
of equipment or spaces in which flammable gases
or dust occur or can collect.
PRUDENCE!
Risk of hand injury
fHands may be crushed during frame and solar
module installation.
fWork must be carried out by trained personnel
only.
fWear protective gloves!
PRUDENCE!
Beware of falling objects
fTools, mounting materials or solar modules may
fall from the roof during installation and injure
persons below.
fBlock o the area at risk on the ground before
starting installation work and warn persons in the
vicinity.
DANGER!
Risk of fatal electric shock
fSolar modules generate power as soon as they
are exposed to light. The voltage of a single solar
module is less than 50 V direct current (DC). When
several solar modules are connected in series, the
voltages accumulate and can be dangerously high.
When several solar modules are connected in par-
allel, the currents are cumulative. Although touch
protection is provided in the form of the fully insu-
lated plug contacts, the following points must be
observed when handling the solar modules to avo-
id risk of fire, sparking and fatal electric shock:
fDo not install solar modules and lines with wet
sockets and plugs!
fAll work on the lines must be carried out with
extreme caution!
fHigh contact voltages can occur in inverters even
when disconnected!
fCaution is advised in all work performed on the
inverter and lines!
