D) Protection Against Wrong Polarity; Fuse Replacement - VOLTCRAFT SLS-150-12 Bedienungsanleitung

In this case, the inverter will switch itself off. After the inverter has cooled off sufficiently, it will
switch on again.

d) Protection against wrong polarity

If the polarity of the input is swapped when connecting, the inverter will not work and cannot
be switched on.
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 (-).
The polarity of the cigarette lighter plug must match that of the cigarette lighter socket used.

9. fUSE REPLaCEMENT

If the fuse in the cigarette lighter of the inverter has tripped, it must be replaced as follows:
• Disconnect the consumer from the inverter, pull the mains plug of the consumer from the
socket of the inverter.
• Pull the cigarette lighter plug of the inverter from the cigarette lighter socket.
• Remove the cause that tripped the fuse. This may be a connection with swapped polarity or
a consumer connected to the inverter with a too-high power consumption.
• Open the cigarette lighter plug by unscrewing the knurled nut at the tip of the plug.
• Replace the defective fuse by a new one of the same build. Observe the print on the fuse or
the chapter "Technical data".
• Screw together the cigarette lighter plug, tighten the knurled nut by hand.
• The inverter can now be put into operation again.
