WARNING
!
CAUTION
This 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.
Be 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.
This instrument is designed for installation in an enclosed
instrumentation panel. All high-voltage connections such
as power supply terminals must be enclosed in the
instrumentation panel to avoid electric shock by operating
personnel.
All precautions described in this manual should be taken to
avoid damage to the instrument or equipment.
All wiring must be in accordance with local codes and
regulations.
All wiring must be completed before power is turned on to
prevent electric shock, instrument failure, or incorrect
action.
The power must be turned off before repairing work for
input break and output failure including replacement of
sensor, contactor or SSR, and all wiring must be
completed before power is turned on again.
To prevent instrument damage or failure, protect the power
line and the input/output lines from high currents with a
protection device such as fuse, circuit breaker, etc.
Prevent metal fragments or lead wire scraps from falling
inside instrument case to avoid electric shock, fire or
malfunction.
Tighten each terminal screw to the specified torque found
in the manual to avoid electric shock, fire or malfunction.
For proper operation of this instrument, provide adequate
ventilation for heat dispensation.
Do not connect wires to unused terminals as this will
interfere with proper operation of the instrument.
Turn off the power supply before cleaning the instrument.
Do not use a volatile solvent such as paint thinner to clean
the instrument. Deformation or discoloration will occur. Use
a soft, dry cloth to remove stains from the instrument.
To avoid damage to instrument display, do not rub with an
abrasive material or push front panel with a hard object.
Do not connect modular connectors to telephone line.

Altitude up to 2000 m
(3) Avoid the following when selecting the mounting location:
• Rapid changes in ambient temperature, which may cause
condensation.
• Corrosive or inflammable gases.
• Direct vibration or shock to the mainframe.
• Water, oil, chemicals, vapor or steam splashes.
• Excessive dust, salt or iron particles.
• Excessive induction noise, static electricity, magnetic fields or
noise.
• Direct air flow from an air conditioner.
• Exposure to direct sunlight.
• Excessive heat accumulation.
(4) Mounting consideration
• Install the module 200 mm away from the main power line.
• Ensure at least 50 mm space on top and bottom of the control
unit for maintenance and environmental reasons.

5.5 Jointing Each Module
Up to 31 SRVs consisting of the each modules can be jointed
together. Joint these modules according to the following
procedure.
Jointing procedures
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
To prevent electric shock or instrument failure, do
not turn on the power until all the wiring is completed.
6.1 Wiring Cautions
For thermocouple input, use the appropriate compensation wire.
For RTD input, use low resistance lead wire with no
difference in resistance between the three lead wires.
To avoid noise induction, keep input signal wire away from
instrument power line, load lines and power lines of other
electric equipment.
If 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.
Power supply wiring must be twisted and have a low voltage
drop.
For an instrument with 24 V power supply, supply power from
a SELV circuit.
A suitable power supply should be considered in the end-use
equipment. The power supply must be in compliance with a
limited-energy circuits (maximum available current of 8 A).
