4-5.Wiring
(1) Follow the terminal layout shown in section 4-6 and make sure to
carry out the correct wiring.
(2) Press-fit terminal must fit an M3.5 screw and have a width of 7 mm
or smaller.
(3) In the case of the thermocouple input, use a compensating conductor
compatible with the type of thermocouple selected.
(4) In the case of R.T.D. input, the resistance of a single lead wire must
be 5Ω or less and the three wires must have the same resistance
value.
(5) The input signal wire must not be accommodated with a high-
voltage power cable in the same wiring conduit or duct.
(6) Shielded wire (one-point grounding) is effective to avoid
electrostatic induction noise.
(7) An effective way to avoid magnetic induction noise is to twist the
input wires at short and equal intervals.
(8) The wiring for power supply must be a 600V vinyl insulated wire or
cable having a cross-section area of 1 mm
2
or larger or a wire or
cable of the same or better performance.
(9) The wire for grounding must be larger than 2 mm
2
and must be
grounded at a grounding resistance of 100Ω or lower.
(10) Noise filter
If the instrument appears to
have noise interference caused
by the power supply, use a
noise filter to prevent erroneous
functioning.
Install a noise filter on the
grounded panel and make the
wire connecting the noise filter
OUT terminal and the power
supply terminal on the controller as short as possible.

Make this wire as short as possible.
Controller
• When wiring, make sure to disconnect the power supply.
Otherwise an electric shock may result.
• Make sure the protective conductor terminal ( ) is grounded.
Otherwise an electric shock may result.
• Do not touch terminals or other charged elements with power
supplied after wiring.
