■ INSTRUCTION MANUALThis manual describes necessary points of caution whenyou use this product, including installation, connection andbasic maintenance procedures.

■ 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 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 continuousvibration. 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 drivecable, 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.
■ 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.

Unused channels left open are equal to the burnout, whichturns the red ERR LED on and sets a burnout flag at the
PLC or the host device.
When you choose B (RH) thermocouple, shortcircuiting
across the terminal may not be effective to cancel theburnout flag. Be sure to use the PC Configurator Software(model: R3CON).
Unused channels can be specified and set so on the PC
Configurator Software without needing to short at the fieldterminals.
