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-safeINFOID: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 wh
en 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 wh
en 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 wh
en 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.
