WIRING OF I/O NETWORK AND FNET
:
1)
Phone cable (unshielded) 2 wire (twisted pair) + a single wire
(2x2x0.5mm + 1x0.5mm). One wire pair will not be used.
or
2) Unshielded 2 wire twisted pair (1x2x0.5mm or 1x2x0.8mm)
Max. length of both networks: wire: ø0,5mm --> 900m.
wire: ø0,8mm --> 1300m.
Connect Fancom equipment according to the prevailing
standards of the local electricity company.
