Replacement of Switching Power Supply Unit

The life of the switching power supply unit (5 VDC/24 VDC) 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 to 10 years), replace
the power supply unit every five (5) years for preventive maintenance.
[Replacement procedures]
1) Turn off the power breaker and disconnect the power supply plug from the
power source.
2) Disconnect the ACIN connector from the controller.
3) Remove the key from the controller.
4) Remove eight (8) countersunk screws (M3 x 6) that secure the cover, and then
remove the cover from the main body.
