PRECAUTIONS
I
Twisted-wire-pair cables must be connected
so that they
may not
be
influenced by noise or surge induction.
(1) Do not lay the cables close to or bind them together with main circuit
wires. (allow 100 mm or more clearance)
(2) When connecting to the remote module terminal block, allow maximum
clearance between twisted-wire-pair cables and module power supply
lines and I/O signal wires.
(3) Do not use a part of twisted-wire-pair cables (such as one pair among
3
pairs) for power supply.
