POINTS OF CAUTION

 

POWER INPUT RATING & OPERATIONAL RANGE

• Locate the power input rating marked on the product and 

confirm its operational range as indicated below:

    85 – 132V AC rating: 85 – 132V, 47 – 66 Hz, approx. 6VA
    12, 24 and 48V DC ratings: Rating ±10%, approx. 3.3W
    110V DC rating: 85 – 150V DC, approx. 3.3W

 

GENERAL PRECAUTIONS

• Before you remove the unit from its base socket or mount 

it, turn off the power supply and input signal for safety.

 

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 -5 to +60°C 

(23 to 140°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
