zThis is a Class A instrument. In a domestic environment,
this instrument may cause radio interference, in which
case the user may be required to take adequate
measures.
zThis instrument is protected from electric shock by
reinforced insulation. Provide reinforced insulation
between the wire for the input signal and the wires for
instrument power supply, source of power and loads.
zBe sure to provide an appropriate surge control circuit
respectively for the following:
−If input/output or signal lines within the building are
longer than 30 meters.
−If input/output or signal lines leave the building,
regardless the length.

5.5 Jointing Each Module
Up to 31 SRXs consisting of the each modules can be jointed
together. Joint these modules according to the following
procedure.
Jointing procedure
1. Mount the modules on the DIN rail and then joint these
modules together with the joint connector while sliding the
relevant module.
2. Lift each of the joint tabs located at the top and bottom of the
module and then insert it in the slot of the adjacent module to
fix these two modules.
For panel mounting, first joint each module and then
mount it on the panel.

6. WIRING
6.1 Wiring Cautions
zFor thermocouple input, use the appropriate compensation
wire.
zFor RTD input, use low resistance lead wire with no
difference in resistance between the three lead wires.
zTo avoid noise induction, keep input signal wire away from
instrument power line, load lines and power lines of other
electric equipment.
zIf there is electrical noise in the vicinity of the instrument that
could affect operation, use a noise filter.
- Shorten the distance between the twisted power supply wire
pitches to achieve the most effective noise reduction.
- Always install the noise filter on a grounded panel.
Minimize the wiring distance between the noise filter output
and the instrument power supply terminals to achieve the
most effective noise reduction.
- Do not connect fuses or switches to the noise filter output
wiring as this will reduce the effectiveness of the noise filter.
zPower supply wiring must be twisted and have a low voltage
drop.
zFor an instrument with 24 V power supply, supply power from
a SELV circuit.
