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
