3. ELECTRICAL CONNECTION OF THE FG-SYS DIGITAL UNIT
Connections are done on the electronic board of the digital unit. The connector blocks are directly
accessible and removable (male parts) on the FG-SYSF and E; for the FG-SYS F (metal enclosure
wall mounted version), it is necessary to turn the key button of the front face to open it.
See Appendix n°1: “FG-SYS E or F Digital Unit Connection” page 57, and also available separately
inside the unit.
