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.
• Use a suitable connection cable with a sufficiently large line cross-section. If the
line cross-section is too small, the connection cable may grow hot. There is a
danger of fire!
very strong overheating may also cause a defect to the insulation of the con-
nection cable, which may cause short circuit. There is a risk of explosion by the
rechargeable battery.
• Keep the connection cable as short as possible.
• The longer the connection cable, the larger the line cross-section has to be.
• 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. The red
clamp of the inverter is the plus pole (+), the black clamp is the minus pole (-).
• The inverter 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.
• 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 resistances 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.
