 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.

INSTALLATION

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