System Description

INFOID:0000000009174842

• When turning ON the AC 120V outlet main switch with the ignition switch ON, the Indicator turns ON and the

inverter unit is activated allowing the use of devices up to 150W.

• The inverter unit converts 12V DC to 120V AC and outputs the converted voltage to the AC 120V outlet two

seconds after the AC 120V outlet main switch is turned ON.

Fail-safe

INFOID:0000000009174843

When a malfunction listed below occurs, the inverter unit turns OFF the AC 120V outlet main switch indicator

and stops the output.

Malfunction item

Fail-safe condition

Fail-safe cancellation condition

Inverter unit power sup-
ply voltage is greater than
15V

When inverter unit input voltage rises above 15V, the
output will be suspended to protect the inverter unit.

After the inverter unit power supply voltage drops
below 15V, the AC 120V outlet main switch ON

⇒

OFF

⇒ ON operation allows normal return.

Inverter unit power sup-
ply voltage is less than
11.5V for 2 seconds or
more

When inverter unit input voltage is lowered, the out-
put will be suspended to protect the battery from run-
ning out.

After the inverter unit power supply voltage rises
above 11.5V, the AC 120V outlet main switch ON

⇒

OFF

⇒ ON operation allows normal return.

Inverter unit power sup-
ply voltage is less than 9V

Inverter unit AC 120V
output voltage is greater
than 170V

When inverter unit AC 120V output voltage is greater
than 170V, the output will be suspended.

After the inverter unit AC 120V output voltage drops
below 170V, the AC 120V outlet main switch ON

⇒

OFF

⇒ ON operation allows normal return.

Inverter unit input current
is greater than 13.3A

When inverter unit input current rises above 13.3A,
the output will be suspended to prevent over current
(e.g., connecting an electric appliance exceeding
rated output).

After the inverter unit input current drops below
13.3A, the AC 120V outlet main switch ON

⇒ OFF

⇒ ON operation allows normal return.

Inverter unit is overheat-
ed

When the inverter unit is overheated [thermistor tem-
perature above 100

°C (212°F)], the output will be

suspended to protect the inverter unit.

After the inverter unit temperature is lowered, the
AC 120V outlet main switch ON

⇒ OFF ⇒ ON op-

eration allows normal return.

Inverter unit output signal
(AC 120V output signal)
is shorted

When inverter unit output signal is shorted, the out-
put will be suspended.

After recovering from inverter unit output signal
short, the AC 120V outlet main switch ON

⇒ OFF

⇒ ON operation allows normal return.

CAUTION:

• To measure AC 120V 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 120V output signal, voltage cannot be measured

accurately without using a circuit tester that can measure true RMS (root mean square).
