Safety precautions
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.
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.

•
When joining functional modules of the same type:
Up to 16 modules
•
When joining functional modules of two or more different types: Up to 31 modules
(However, the maximum joinable number of functional modules of the same type is 16.)

3. WIRING
3.1 Wiring Cautions
•
To avoid noise induction, keep communication 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).
•
Supply the power to only one of the joined modules. When power is supplied to any one of the
joined modules, all of the joined modules will receive power.
•
Select the power capacity which is appropriate for the total power consumption of all joined
modules and the initial current surge when the power is turned on.
Power consumption (at maximum load):
30 mA max. (at 24 V DC)
Rush current: 10 A or less
•
When connecting the wiring to the power supply terminals on the base, use the specified
solderless terminals. Only these specified solderless terminals can be used due to the insulation
between the terminals.
