■INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
POINTS OF CAUTION
■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.
■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).
