1.2 How to Install
NOTE
To install the controller, select a location where:
1. no one may accidentally touch the terminals,
150mm150mm
150mm
150mm
2. mechanical vibrations are minimal,
3. corrosive gas is minimal,
4. temperature can be maintained at about 23C and
the fluctuation is minimal,
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 controller directly on flammable items or equipment.
If the controller has to be installed close to flammable items or equipment, be sure to
provide shielding panels all around the controller, 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 ship-
ping.
●Installation Position
Install the controller at an angle within 30from horizontal with the front panel facing up-
ward. Do not install it facing downward. The position of right and left sides should be hori-
zontal.

■How to Install
CAUTION
Turn off the power to the controller before installing it on the panel because there is a
possibility of electric shock.
After opening the mounting hole on the panel, follow the procedures below to install the
controller:
1. Insert the controller 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 controller as shown in the figure
below, then tighten the screws of the brackets. Take care not to overtighten them.

1.3 How to Connect Wires
CAUTION
1) Before carrying out wiring, turn off the power to the controller and check that the
cables to be connected are not alive with a tester or the like because there is a possi-
bility of electric shock.
2) For the protection and safe use of the controller, be sure to place a circuit breaker
(conforms with IEC60947, 5A, 100V or 220V AC) near the controller where the
breaker can easily be operated. In addition, be sure to indicate that it is the instrument
to cut the power supply of the controller.
3) 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) Control output relays may be replaced. However, because they 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 a possibility of being struck by external lightning surge, use the arrester
to protect the instrument.
