c) Connection to a Direct Voltage Source

• Do not wear any metal or conductive materials, such as jewellery (necklaces, bracelets, rings, etc.). A
short circuit at the rechargeable battery or inverter causes a danger of injury, fire and explosion.
• For a converter with pole terminals, a suitable connection cable with a sufficiently large line cross-sec-
tion must be used (see chapter "Technical Data"). The longer the connection cable, the larger the line
cross-section has to be. If the line cross-section is too small, the connection cable may grow hot. There
is a danger of fire! Keep the connection cable between the converter and the rechargeable battery as
short as possible for this reason.
Very strong overheating may also cause a defect to the insulation of the connection cable, which may
cause short circuit. There is a risk of explosion of the rechargeable battery, as well as danger of fire!
A converter with pole terminals should never be directly connected to a direct voltage source (e.g. a car
battery), but only via an accordingly sized fuse. This fuse should be placed as close as possible to the
direct voltage source.
• At a converter with cigarette lighter plug (types "SW-100" and "SW-150"), the connection cable must
not be cut off, shortened or extended.
• Before the inverter is connected to the direct voltage source, it must be switched off.
• Always observe the correct polarity (plus/+ and minus/-) for connection of the converter.
• Depending on the power taken from the inverter, the direct voltage source (e.g. a car battery) must be
able to supply the corresponding current strength.
• Check all connections for tight fit and good electrical contact at regular intervals. High transfer resist-
ances not only reduce the performance of the inverter but also may cause overheating and fire.
• The inverter must not be connected to electrical systems (e.g. a motor vehicle) where the plus pole is
grounded or connected to the chassis of the vehicle.

d) Mains Voltage Output

• Do not pull the mains plug from the mains socket of the inverter by pulling the cable.
• Never connect the output of the inverter to another 230 V source (e.g. a mains socket). The inverter
must not be used to feed mains voltage into an electrical building installation.
• In the deactivated condition, the charged capacitors may still cause the alternating voltage to be
pending at the mains sockets of the converter.

e) Operation

• Do not operate the inverter unsupervised.
• Never touch the blank live contacts or connection terminals on the input side of the converter.
• Even after triggering the internal protective device or device protection, parts of the converter may still
be live!
• The housing of the inverter will heat up in operation (depending on the output). Therefore, always
observe sufficient ventilation of the inverter; never cover it in operation. Never close the ventilation slots
of the inverter.
Keep a minimum distance of 10 cm from other devices around the housing of the inverter.
