WARNING
■
Do not connect or disconnect the motor connectors while the power to the robot
system is turned ON. Connecting or disconnecting the motor connectors
the power ON is extremely hazardous and may result
in serious bodily injury as
the Manipulator may move abnormally, and also may result in
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.
DO NOT connect it directly to a factory power source.
performing any replacement procedure, turn OFF the Controller and
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.
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.
Attempting to charge
Disassembling
Connecting batteries improperly
Exposing to fire
Forcing discharge
Deforming by pressure
Short-circuit (Polarity; Positive/Negative)
Heating (85 °C or more)
Soldering the terminal of the lithium battery
directly
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.
The life span of the lithium battery varies depending on the energizing hours and
installation environment of the Manipulator. It is about 7 years as a rough guide (when
the Manipulator is connected to power for 8 hours a day). When the Manipulator 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.
For EPSON RC+ 7.0, the recommended replacement time for the battery can be checked
in the [Maintenance] dialog box.
Reference: Maintenance 4. Alarm
The battery may run out if it passes the recommended replacement time.
If no warnings of voltage reduction occur, the calibration for all joints is not necessary.
You need to perform calibration if the position moves from the originals after replaced the
battery.
Be sure to use the designated parts for the lithium battery.
Reference: Maintenance 22. Maintenance Parts List
Be careful of the battery polarity to connect it correctly.
