POINTS OF CAUTION ■ HOT INSERTION/REMOVAL OF MODULES Removing or replacing modules does not affect other modules on the same backplane. It is possible to replace them without removing the power supply. However, replacing multiple modules at once may greatly change line voltage levels. We recommend that you replace them one by one. ■ 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 (power supply, input and output) 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.

■ STATUS INDICATOR LED RUN indicator: Bi-color (red/green) LED; Red when connected to a host PC/PLC via internal bus A Green when connected to a host PC/PLC via internal bus B (R3-US4W only) Amber when connected to a host PC/PLC via both buses (R3-US4W only) ERR indicator: Bi-color (red/green) LED; Red with the input circuit abnormality Green in normal operating conditions
■ UNUSED INPUT CHANNELS Setting the unused channels as “Unused” with the configurator software (model: R3CON) prevents the error due to open circuit.

Note 1: Remove CJC sensor for RTD or potentiometer input. The CJC sensor does not affect to DC voltage input. Note 2: Be sure to eliminate noise as much as possible by e.g. using shielded cables. Ground the signal shield to a most stable earth point in the environment. Note 3: The temperature imbalance around the terminal affects greatly the cold junction compensation accuracy. In order to minimize such imbalance, do not expose the input terminals directly to the wind from a cooling fan.
