1.
Fan
This fan is for cooling the unit. Install the unit where the
ventilation holes will not be blocked.
Note:
If the fan is stopped while the power is on, the “FAN
STOPPED” (
➝
page 121) warning is displayed. Stop opera-
tion and turn off the unit immediately, and contact your dealer.
2.
DC IN connector
Connect a 12 V DC power supply.
When the voltage drops to approximately 10.0 V, the unit
is shutdown automatically.
Afterwards, the power is not restored automatically even if
the power supply voltage recovers. Press and hold the
[
] button for at least 1 second to turn the power on.
Note:
When using an external DC power supply, be sure to check
the external DC power supply ratings and use one that is suit-
able for the unit.
Check the pin assignment of the DC output connector of the
external DC power supply and the DC IN connector on the
unit, and connect the connectors with the correct polarity. In-
correct connection of the +12 V power supply to the GND
connector may cause a fire or injury.
