YASKAWA MOTOMAN MYS450L Operating And Maintenance Instructions Manual page 48

Use meticulous care when handling the lithium battery. Improper
handling of the lithium battery as mentioned below is extremely
hazardous. It can lead to heat generation, leakage, explosion, or
inflammation, and may cause serious safety problems.
<Improper Handling>

Do not charge

Disassembly

Incorrect Installation

Exposing to Fire

Forced Discharge Deformation by Pressure

Short-circuit (Polarity; Positive/Negative)

Do not heat (100C or more)

Do not solder the lithium battery on directly
When the lithium battery power is low, an error will occur to warn the user about the low
battery status when the Controller is turned ON (when software is started up).
When the error occurs, the position data in motors will be lost and all joints need to be
completely calibrated again.
The life span of the lithium battery is 3 years. Even if the robot is constantly connected to
power, the lithium battery needs to be replaced every 3 years.
9.2.2 Replacing the Battery Unit (Lithium Battery)
Battery unit (lithium battery) removal
1. Turn OFF the Controller
2. Push down the shaft to its lower limit while pressing the brake release button switch. Be
sure to keep enough space and prevent the end effector hitting any peripheral equipment.
The brake release button switch is applied to both Z and U. When the brake release
button switch is pressed, the respective brakes of the Z and U are released
simultaneously.
Be careful of the shaft falling and rotating while the brake release button switch is being
pressed because the shaft may be lowered by the weight of an end effector.
3. Remove the arm top cover
4. Connect the connector of the new lithium battery to the battery board.
User the unused connector of the two connectors X60A, X60B on the upper part of the
battery board.
