CAUTION
This is a Class A instrument. In a domestic environment, this instrument may cause radio
interference, in which case the user may be required to take adequate measures.
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.

4.1 Wiring
To prevent electric shock or instrument failure, do not turn on the power until all
the wiring is completed.
CAUTIONS
Power supply wiring:
WARNING
!
Use a power supply is within the power supply voltage variation range.
For power supply wires, use twisted wires with low voltage drop.
Separate each of the instrument power supply line, input/output circuit power supply line,
equipment and motor power supply line, and operating circuit power supply line.
If a noise source is near the instrument and could affect the instrument, use a noise
filter.
− Shorten the distance between twisted power supply wire pitches. The shorter the
distance between the pitches, the more effective for noise reduction. In addition,
always ground noise filter.
− Always install the noise filter on the grounded panel. Also minimize the wiring distance
between the noise filter output side and instrument power supply terminals to ensure
the effectiveness of the noise filter.
− Do not connect fuses or switches on the wiring of the noise filter output side, since
these may reduce the effectiveness of the noise filter.
− To obtain a satisfactory noise filter effect, select the most suitable type after due
consideration of instrument power supply voltage and filter frequency characteristics.
To the instrument with power supply of 24 V, please be sure to supply the power from
SELV circuit.
Grounding wire wiring:
Ground the instrument separately from other equipment. The grounding resistance should
be 100 Ω or less. Use grounding wires with a cross section area of 2.0 mm
