BEFORE USE ....

POINTS OF CAUTION

Thank you for choosing us. Before use, please check contents of the package you received as outlined below.
If you have any problems or questions with the product,please contact our sales office or representatives.

■ 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.

■ PACKAGE INCLUDES:
4 – 20mA input module........................................................(1)■ MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.
■ INSTRUCTION MANUALThis manual describes necessary points of caution when
you use this product, including installation, connection andbasic maintenance procedures.

■ GENERAL PRECAUTIONS• DO NOT set the switches on the module while the poweris supplied. The switches are used only for maintenancewithout the power.
■ ENVIRONMENT• Indoor use• When heavy dust or metal particles are present in theair, install the unit inside proper housing with sufficientventilation.
• 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 “Unused” with PC Configurator software: R3CON. Unused channels left open may
be 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 supplied, however, a warm up for 10 minutes is required forsatisfying complete performance described in the datasheet.

INSTALLATIONUse the Installation Base (model: R3-BSx).
