Connections
The instrument has 4 rear connectors CN1 to CN4 in its unique
format. The connectors layout is shown in the figure. All the aerial
terminals supplied for the connection are of CAGE CLAMP® type
technology.
Terminals for
CN2
connector admit cables with section from
0.2mm² up to 1.5mm² (AWG 24÷14).
Terminals for
CN1
,
CN3
and
CN4
connectors admit cables with
section from 0.08mm² up to 2.5mm² (AWG 28÷12).
To perform wiring connections, strip the cable leaving from 7 to
10mm exposed to air, insert it in the proper terminal while
pushing down the key insertion tool to open the clip inside the
connector. Release the key tool to fix wire to the terminal.
Proceed in the same way for the rest of terminals. Once all
connections are done, plug connectors to the instrument.
