19. LOADING AND INSTALLATION
(2) Wiring I/O equipment
(a) The applicable wire size for a terminal block connector is 0.75 to 2mm
2
. It is
recommended to use wire of 0.75mm
2
for easy use.
(b) Run the input line and output line away from each other.
(c) Separate the I/O signal lines (including common line) at least 100mm (3.94inch)
away from the main circuit line carrying high voltage and large current.
(d) If it is not possible, use a batch shielding cable and ground it on the PLC side.
However, ground it on the opposite side in some cases.
(e) When ducts are used for wiring, securely ground them.
(f) Separate the 24VDC I/O cables from the 100VAC and 200VAC cables.
(g) In a long distance wiring of 200m (656.2ft.) or longer, leak current due to
capacitance may cause failure.
(h) As protective measures against lightning surges, separate the AC wiring from
the DC wiring and connect a lightning surge absorber as shown in (1) (i).
Failure to do so increases the risk of I/O equipment failure due to lightning.
POINT
(1) Ground the lightning surge absorber (E1) and the PLC (E2) separately from
each other.
(2) Select a lightning surge absorber whose voltage does not exceed the
maximum allowable circuit voltage even when line voltage reaches the
maximum.
CAUTION
Do not install the control lines or communication cables together with the main
circuit or power lines, or bring them close to each other.
Keep a distance of 100mm (3.94inch) or more between them.
Failure to do so may cause malfunctions due to noise.
