Connections
Basic instrument has two rear connectors
CN1
and
CN2
. If 2RE
output option card is installed, two more connectors
CN3
and
CN4
appear. See all four connectors location and their pin out in
the right figure. All female provided terminal connectors are of
CAGE CLAMP
®
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.
