9.2  Construction of Internal Assembly

The internal assembly of this controller consists of three boards – display board, power supply board, and 

output board. The power supply board and output boards are individually coupled with connectors CN and 

CN2 to their mating connectors CN and CN2 on the display board. The rear panel has terminal blocks for 

external connections. (For details of the terminal blocks, see Sections 5.3 and 5.4.)

 Take off long screws at back of the controller. 

  Separate the front panel (display board) from the 

housing. 

 NOTE 

:

  Since the power board and output board are 

connected with interconnect cable unit, slide 

both of them out of the frame when you remove 

them.
