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 -5 to +55°C     

(23 to 131°F) with relative humidity within 30 to 90% RH 
in order to ensure adequate life span and operation.

• Be sure that the ventilation slits are not covered with ca-

bles, etc.

 

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.

• With voltage output, do not leave the output terminals 

shortcircuited for a long time.  The unit is designed to 
endure it without breakdown, however, it may shorten ap-
propriate life duration.
