C) Connection To A Direct Voltage Source - VOLTCRAFT MSW 150 Bedienungsanleitung

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 causes a danger of injury, fire and explosion.
• The connection cable with cigarette lighter plug is firmly installed to the inverter. If
an extension cable is used, it must have a sufficiently sized 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.
• Always observe the correct polarity (plus/+ and minus/-) for connection. The
middle contact of the cigarette lighter plug is the plus pole (+), the outer contact is
the minus pole (-).
Check the polarity of the cigarette lighter socket used before connecting the
inverter.
• 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.
However, never replace the fuse in your vehicle for the cigarette lighter socket
with any other fuse (with a higher rated value), since this may damage the vehicle
electronics. There also is a danger of fire!
• 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.
