11. Replacing the Battery Unit

■ Do not connect or disconnect the motor connectors while the power to the robot
system is turned ON. Connecting or disconnecting the motor connectors with
the power ON is extremely hazardous and may result in serious bodily injury as
the Manipulator may move abnormally, and also may result in electric shock
and/or malfunction of the robot system.
■ To shut off power to the robot system, disconnect the power plug from the power
source. Be sure to connect the AC power cable to a power receptacle.
WARNING
DO NOT connect it directly to a factory power source.
■ Before performing any replacement procedure, turn OFF the Controller and
related equipment, and then disconnect the power plug from the power source.
Performing any replacement procedure with the power ON is extremely hazardous
and may result in electric shock and/or malfunction of the robot system.
■ Take meticulous care when handling the lithium battery. Improper handling of
the lithium battery as mentioned below is extremely hazardous and may result in
heat generation, leakage, explosion, or inflammation.
It also may cause serious safety problems.
<Improper Handling>
Attempting to charge
Disassembling
Connecting batteries improperly
WARNING
Exposing to fire
Forcing discharge
■ When disposing the battery, consult with the professional disposal services or
comply with the local regulation. Make sure that the battery terminal is insulated,
even for a used buttery. If the terminal contacts with the other metals, it may short
and result in heat generation, leakage, explosion, or inflammation.
In case of the low lithium battery power, the error to warn the voltage reduction occurs at
the Controller startup (the software startup). All position data will be lost and you will
need to calibrate all joints.
The life span of the lithium battery varies depending on the energizing hours and
installation environment of the Controller. It is about 3 years as a rough guide (when the
Controller is connected to power for 8 hours a day). When the Controller is not
connected to power, the battery consumption will significantly increase compared to when
the Controller is energized. If warnings of voltage reduction occur, replace the lithium
metal battery even if it has not reached the above product life.
