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.

5. MOUNTING

To prevent electric shock or instrument failure, always turn off the power before mounting or removing the instrument.

5.1 Mounting Cautions

(1) This instrument is intended to be used under the following

environmental conditions. (IEC61010-1) [OVERVOLTAGE CATEGORY II, POLLUTION DEGREE 2]

(2) Use this instrument within the following environment conditions.

• Allowable ambient temperature: −10 to +50 °C

• Allowable ambient humidity: 5 to 95 % RH

(Absolute humidity: MAX. W. C 29.3 g/m

• Installation environment conditions: Indoor use 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).
