POINTS OF CAUTION
■HOT INSERTION/REMOVAL OF MODULES
•Removing or replacing modules does not affect other mod-
ules 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 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.
■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
Use the Installation Base (model: R3-BSx).
