1.no one may accidentally touch the terminals,

2.

mechanical vibrations are minimal,

3.

corrosive gas is minimal,

150 mm

4.

temperature can be maintained at about 23 C and

5.

no direct radiant heat is present,

6.no magnetic disturbances are caused,

7.no wind blows against the terminal board (reference junction compensation element),

8.no water is splashed,

9.no flammable materials are around,

Never place the indicator directly on flammable items or equipment.

If the indicator has to be installed close to flammable items or equipment, be sure to provide shielding panels all around the indicator, at least 150 mm away from every side; the panels should be made of either 1.43 mm-thick metal-plated steel plates or 1.6 mm-thick uncoated steel plates.

NOTE

Never touch the opening at the bottom of the case. It is to be used in the factory at shipping.

● Installation Position

Install the indicator at an angle within 30 from horizontal with the front panel facing upward. Do not install it facing downward. The position of right and left sides should be horizontal.

■ How to Install

Turn off the power to the indicator before installing it on the panel because there is a possibility of electric shock.

CAUTION

After opening the mounting hole on the panel, follow the procedures below to install the indicator:

1.Insert the indicator into the opening from the front of the panel so that the terminal board on the rear is at the far side.

2.Set the brackets in place on the top and bottom of the indicator as shown in the figure below, then tighten the screws of the brackets. Take care not to overtighten them.

Direction to insert the indicator

Insert the indicator into the opening at the front of the panel.

1.3How to Connect Wires

1)Before carrying out wiring, turn off the power to the indicator and check that the cables

to be connected are not alive with a tester or the like because there is a possibility of electric shock.

CAUTION 2) Wiring must be carried out by personnel who have basic electrical knowledge and practical experience.

NOTE

1)Provide power from a single-phase instrument power supply. If there is a lot of noise in the power line, insert an insulating transformer into the primary side of the line and use a line filter (recommended part: ZAC2205-00U from TDK) on the secondary side.

As a countermeasures against noise, do not place the primary and secondary power cables close to each other.

2)For thermocouple input, use shielded compensating lead wires for wiring. For RTD input, use shielded wires that have low conductor resistance and cause no significant differences in resistance between the three wires.

The cables to be used for wiring, terminal specifications, and recommended parts are as shown below.

3)Alarm output relays have a life of 100,000 times that of the resistance load, use auxiliary relays to turn on/off a load.

4)The use of inductance (L) loads such as auxiliary relays, motors and solenoid valves causes malfunction or relay failure; always insert a CR filter for use with alternating current or a diode for use with direct current, as a spark-removal surge suppression circuit, into the line in parallel with the load.

5)When there is possibility of being struck by external lightening surge, use the arrester to protect the instrument.
