• When the Power Supply Box Main Disconnect Switch is ON, the electrical access panel door locks
automatically to prevents access.
• The door on the Power Supply box can only be accessed with a key to prevent unauthorized access
to the main electrical compartment.
• When the Docking Target detects an AMR or external battery, a series of interlocking checks are
performed to confirm that all devices are in an operational state before charging will begin.
The Power Supply Box uses a 4 meter long power cord (25.4 mm diameter) to transfer power to the
Docking Target.
Power Supply Box
The Power Supply Box has LED indicators to display the status of the unit as described below. A Serv-
ice button is also present for use when connecting a fully depleted battery.
The Power Supply Box has a Main Disconnect Switch that turns the unit ON or OFF. When the Main
Disconnect Switch is placed in the vertical position (ON position), the unit powers ON and illuminates
all LEDs on the front panel of the Power Supply Box for 2 seconds. The Power Supply Box is opera-
tional at this moment. Use the LEDs determine the operational status of the Power Supply Box. Plac-
ing the Main Disconnect Switch in the horizontal position (OFF position) will remove power from the
Power Supply Box.
The Power Supply Box performs several diagnostic tests. If a problem is detected, the Power Supply
Box enters a safe state in which all charging power turned OFF and the red LED flashes. Refer to
5-4-2 Battery Charging Problems on page 5-6 for more information.
The Power Supply Box will not automatically charge a battery if it is absolutely depleted.
Pressing the Service button on the Power Supply Box during a charging session will interrupt charg-
ing. Disconnect the battery and then reconnect to resume charging.
Precautions for Correct Use
• It is safe to connect or disconnect the power cord from the Docking Target or battery without
powering OFF the Power Supply Box.
• Always wait until the green OPERATION LED indicator on the Power Supply Box is ON solid
before attempting to charge a battery.
• Do not press the Service button on the Power Supply Box if the yellow DC POWER LED indi-
cator is flashing when there is no battery connected. Contact your OMRON representative if
this condition is present.
