Instructions for
operation
For continuous operation of devices
using the car power inverter
1
the
socket for the electrical system must
have a voltage between 10.5 V
and 14.8 V. Before connecting the
car power inverter
1
, check
whether the voltage supply provides
sufficient power for operation. The
power required for operation can
be calculated as follows:
Operating output of the load (W)
Efficiency (
η)
Input voltage (V)
(
)
Current draw (A) =
Example:
300 W
0.75
12 V
(
)
= 33.3 A
The voltage supply should provide
at least 33.3 A for a continuous
load of 300 W.
Note:
12 V sockets for the electrical
system provide max. 10 A,
therefore in this example, the car
power inverter
1
must be con-
nected directly to the car battery
using the connecting clamps. This
is the only way to ensure continu-
ous output of 300 W.
Attention!
Never connect the car power
inverter
1
to a 24 V electrical
system. Otherwise the device will
be damaged. The device must
only be connected to a voltage
supply with a nominal voltage
of 12 V.
z
Install and secure
The car power inverter
1
should be positioned on a
flat, even surface. Make sure
that there is at least 1 cm free
space around the car power
inverter
1
for air circulation.
