INSTRUCTION MANUAL

This manual describes necessary points of caution when 
you use this product, including installation, connection and 
basic maintenance procedures.

POINTS OF CAUTION

 

CONFORMITY WITH EU DIRECTIVES

• The equipment must be mounted inside the instrument 

panel of a metal enclosure.

• The actual installation environments such as panel con-

figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated 
in a panel system.  The user may have to review the CE 
requirements in regard to the whole system and employ 
additional protective measures to ensure the CE conform-
ity.

 

HOT SWAPPABLE MODULES

• Replacing the module does not affect other modules on 

the same base.  Thus, the module can be replaced while 
the power is ON.  However, replacing multiple modules 
at once may greatly change live voltage levels.  We highly 
recommend to replace them one by one.

 

GENERAL PRECAUTIONS

• DO NOT set the switches on the module while the power 

is supplied.  The switches are used only for maintenance 
without the power.

 

ENVIRONMENT

• Indoor use.
• When heavy dust or metal particles are present in the 

air, install the unit inside proper housing with sufficient 
ventilation.

• Do not install the unit where it is subjected to continuous 

vibration.  Do not subject the unit to physical impact.

• Environmental temperature must be within -10 to +55°C 

(14 to 131°F) with relative humidity within 30 to 90% RH 
in order to ensure adequate life span and operation.

 

WIRING

• Do not install cables close to noise sources (relay drive 

cable, high frequency line, etc.).

• Do not bind these cables together with those in which 

noises are present.  Do not install them in the same duct.

 

UNUSED INPUT CHANNELS

• Set the unused channels to the ranges otherthan 1 – 5 V.  

Otherwise, set them as “Unused” with PC Configurator 
software: R3CON.  Unused channels left open with 1 – 5 V 
setting are equal to the input lower than -15%, which sets 
a data abnormality at the PLC or the host device.

 

AND ....

• The unit is designed to function as soon as power is sup-

plied, however, a warm up for 10 minutes is required for 
satisfying complete performance described in the data 
sheet.

INSTALLATION
