* When using recording paper except for genuine chart, operation is not guaranteed.
5. Restriction of digital recording/printing function
(1) When the chart speed is set to 150mm/H or more, printing function for other than time line, power-on printing,
data printing, list printing and setting change mark is disabled.
(2) Printing is formed with dots of one pin. Therefore, if the power is turned off while characters are being formed,
they cannot be formed correctly. This is not abnormal.

2. Precautions on wiring
Precautions on wiring are described below. Observe them to maintain safety and reliability.
1) Feed power source
For the power source for the unit, use the single-phase power source with stable voltage and without
waveform strain to prevent malfunctions.
(1) Switch and overcurrent protective device
Add a switch and overcurrent protective device (250V, 3A) to the feed power source
to prevent an electric shock on wiring. The unit has no replaceable fuse.
(2) Connect after the power source is turned OFF
When performing power and input/output wiring, make sure to turn OFF the feed
power source to prevent an electric shock.
2) Separate from strong power circuits
For input/output wiring, avoid adjacency or parallel with strong power circuits such as power lines. Separate
50cm or more for adjacency or parallel.
3) Separate thermocouple input from heat sources.
To reduce reference junction compensation errors for thermocouple input, especially separate terminals
from heat sources (heating body). Also, avoid radiation such as direct sunlight.
4) Separate from noise sources.
Separate from noise sources as much as possible. Unexpected troubles may occur. If separation from
noise sources is disabled, implement countermeasures.
Main source Countermeasures
Electromagnetic switch or others
Power line with distortion of wave
Inverter
Thyristor regulator
Insert noise filters between power source and input/output
terminals. CR filters are used in many cases.
! Warning

- 14 -
5) Use crimping terminals.
(1) To prevent looseness or disconnection of terminals and short circuit between terminals, install
crimping terminals to termination of connection cables.
(2) To prevent an electric shock, use crimping terminals with insulation sleeves.

3. Power/protective conductor terminals wiring
1) Power/protective conductor terminals
 Turn OFF feed power source.
Before power/protective conductor terminals wiring, make sure to turn off the feed power
source to prevent an electric shock.
2) Power terminal wiring
Using 600V vinyl insulated cables (AWG20 to 16) as the
power line, install crimping terminals with insulation
sleeves to the termination for wiring.
Note: Use the following standard cables.
(1) IEC 60227-3
(2) ANSI/UL817
(3) CSA C22.2 No.21/49
3) Protective conductor terminal wiring
Make sure to connect to the protective conductor of the
power equipment. Install crimping terminals with
insulation sleeves for wiring.
Grounding wire: Copper cable with AWG20 to 16
(green/yellow)
 mark at power terminals
After wiring the power terminals have power supply voltage applied. Make sure to install
power terminal covers after wiring to prevent an electric shock.
 Pay attention to power supply voltage and noise.
The power supply voltage of the unit is indicated on power terminals. Applying power
other than the indicated one causes accidents or malfunction. In addition, if the power
has noise interference, implement countermeasures such as noise cut transformer
installation.

4. Measurement input terminals wiring
1) Measurement input terminal
Turn OFF the feed power source before
wiring to prevent an electric shock.
Install crimping terminals with insulation
sleeves to input terminals for wiring.
2) DC voltage (current) input wiring
Use instrumentation twisted cables for
measures against noise as input cables.
For current input, connect the shunt resistor
for current input to the channel to be
measured before wiring.
3) Thermocouple (TC) input wiring
Make sure to wire thermocouple cable (or
compensation lead wire) to input terminals of
the unit.
If a copper conductive wire is connected
halfway, big measurement error will be
generated.
In addition, avoid parallel connection of a pair
of thermocouple wires with other instruments
(controller or others) that cause troubles.
4) Resistance thermometer (RTD) input wiring
To prevent measurement errors, use 3-core
cables as the input cable in which lines have
the same resistance.
In addition, one resistance thermometer
cannot be connected in parallel with other
instruments (a controller or others).
mark on measurement input terminals
High voltage may be applied to the measurement input terminals due to common mode
noise. Allowable noise value is 30VAC or 60VDC or less. Check that the voltage is equal
to or less than the allowable value. Do not use the instrument for measurements on
mains circuits. Install terminal covers after wiring to prevent an electric shock and
protect input cables. For thermocouple input, installing terminal covers reduces
reference junction compensation errors.
