The electrical connection is carried out by using a removable 9-pin terminal block. These ter-
minal blocks differ in their connection system (spring terminals or screw terminals, cable
mounting from the front or from the side). For more information, please refer to the chapter ter-
minal blocks for S500-eCo I/O modules
