Component Description
INFOID:0000000006257067
Inverter Unit
INFOID:0000000006257068
The inverter unit converts an applied power supply voltage (approximately DC 12 V) to AC 120 V and outputs
the converted voltage.
AC120 V Outlet Main Switch
INFOID:0000000006257069
The operation of the switch enables the inverter unit to activate/inactivate and turn ON/OFF AC 120 V output.
AC120 V Outlet
INFOID:0000000006257070
The AC 120 V outlet allows using AC 120 V converted in the inverter unit as an outlet.

SYSTEM DESCRIPTION
• When turning ON the AC 120 V outlet main switch with the ignition switch ON, the indicator turns ON and the
inverter unit is activated.
• The inverter unit converts power supply voltage to AC 120 V and outputs the converted voltage to the AC
120 V outlet two seconds after the AC 120 V outlet main switch is turned ON.
Fail-safe
INFOID:0000000006257269
When a malfunction listed below occurs, the inverter unit turns OFF the AC 120 V outlet main switch indicator
and stops the output by operating the fail-safe.
JSMIA0295GB
Malfunction item
Fail-safe condition
Fail-safe cancellation condition
Inverter unit is overheat-
ed
When the inverter unit is overheated, the output
stops to protect the inverter unit.
After the inverter unit temperature is lowered, the
AC 120 V outlet main switch ON
⇒
OFF
⇒
ON op-
eration allows normal return.
Inverter unit power sup-
ply voltage is 11.5 V or
less
When inverter unit input voltage is lowered, the out-
put stops to protect the battery from running out.
Automatic normal return when inverter unit power
supply voltage reaches 11.5 V - 16 V.
Inverter unit power sup-
ply voltage is 16 V - 18 V
When inverter unit input voltage reaches 16 V - 18 V,
the output stops to protect the inverter unit.
Automatic normal return when inverter unit power
supply voltage reaches 11.5 V - 16 V.
Inverter unit power sup-
ply voltage is 18 V or
more
When inverter unit input voltage reaches 18 V or
more, the output stops to protect the inverter unit.
After the inverter unit power supply voltage reaches
11.5 V - 16 V, the AC 120 V outlet main switch ON
⇒
OFF
⇒
ON operation allows normal return.
Inverter unit output cur-
rent is 2.8 A or more
When inverter unit output current reaches 2.8 A or
more, the output stops to prevent over current. (e.g.
connecting an electric appliance exceeding rated
output)
Automatic normal return when inverter output cur-
rent reaches 2.8 A.
Inverter unit output signal
(AC 120 V output signal)
is shorted
When inverter unit output signal is shorted, the out-
put stops.
After recovering from inverter unit output signal
short, the AC 120 V outlet main switch ON
⇒
OFF
⇒
ON operation allows normal return.

CAUTION:
• To measure AC 120 V output signal, always use the circuit tester or oscilloscope AC range.
Never allow the probes to contact each other.
• Because of modified sine wave output of the AC 120 V output signal, voltage cannot be measured
accurately without using a circuit tester that can measure true RMS (root mean square).
