• Waste battery should be disposed of according to the user's in-house
regulations.
• NEVER drop the battery into fire. NEVER short-circuit, charge, disassemble
or heat it. Otherwise, liquid leakage or rupture may be caused.
3.3.4 Replacement of Switching Power Supply Unit
The life of the switching power supply unit (DC5 V/DC24 V) used in the robot
controller differs with the operating conditions. This unit uses an aluminum
electrolytic capacitor, and if the load current is large, the running time is long and the
ambient temperature is high, the life will reduce.
As the life varies largely with the user's operating conditions (5 ~ 10 years), replace
the power supply unit every five (5) years for preventive maintenance.
[Replacement procedures]
1) Turn off the main power switch.
2) Turn off the power breaker.
3) Remove the cover from the controller.
4) Remove the four screws securing the switching power supply unit (PS1).

5) Secure the new power supply unit to the robot controller by tightening the four
screws.
6) Attach the cover to the controller.
