• Locate the power input rating marked on the product and 

confirm its operational range as indicated below:

  100 – 240V AC rating: 85 – 264V, 47 – 66 Hz, approx. 5 – 8VA
  10 – 32V DC rating: 9 – 36V, approx. 3W

 SAFETY PRECAUTION

• Before you remove the unit 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,

• Environmental temperature must be within -25 to +65°C     

(-13 to +149°F) with relative humidity within 0 to 95% 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  (power  supply,  input  and  output) 

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 ....
