Precautions for Correct Use
When the battery is turned OFF, all internal calibration data about the charge level is lost. Turn-
ing the battery ON will activate the battery LED indicators, but the charge level may not be rep-
resented accurately. Charge the battery completely to recalibrate and display the charge level
accurately.
Additional Information

Charging Station
The Charging Station provides both manual and automated methods of recharging the AMR's battery.
A 4 m power cable connects the Power Supply box to the Docking Target. This cable can also be used
for charging a battery outside of the AMR. Refer to Charging a Battery Outside of the AMR on page
4-26 for more information..
The Power Supply Box outputs a maximum of 6.84 kW of power and can charge a completely deplet-
ed battery in 40 minutes.
WARNING
• The AMR battery and the Charging Station outputs have high current. You must
take appropriate precautions to avoid potential short circuit.
• The Charging Station, battery, and AMR transfer high electric power and contain
hazardous voltages. You must take necessary precautions to avoid electric shock.
Follow appropriate Lock-Out, Tag-Out (LOTO) instructions prior to any installation
and maintenance work performed on or near these items.
• If power cords lie on the ground, you must make sure that they are highly visible to
prevent tripping hazards and must be protected from physical damage with barriers
or covers.
WARNING
The Power Supply Box, charging contacts on both the Docking Target and the AMR,
and the drive wheel motors can get hot during operation. Allow these items to cool
down prior to servicing.
Precautions for Safe Use
• In case of fire, use a type ABC or type BC dry chemical fire extinguisher.
• Never access the interior of the AMR while it is connected to the Docking Target.
• Avoid liquid near the Charging Station and the AMR.
Precautions for Correct Use
• Always ship and store the AMR, Power Supply Box, and the Docking Target in an upright po-
sition in a clean and dry area. Do not lay the shipping crates on their sides or any other non-
upright position. This could damage the Power Supply Box and the Docking Target.
• You must route and secure the power cords properly. They must be secured in such a way
that prevents straining of the connection points.
The following safety measures associated with high power transfer are described below.
