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:

 

AC Power

  M2: 100 – 240 V AC, 50 – 60 Hz, maximum 6 VA
  (85 – 264 V AC, 47 – 66 Hz)

 

DC Power

  R: 24 V DC (24 V ±10%), maximum 3.5 W
  P: 110 V DC (85 – 150 V), maximum 3.5 W

 

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 +55°C     

or 23 to 131°F (-25 to +55°C or -13 to +131°F with Option 
/T) with relative humidity within 30 to 90% RH in order 
to ensure adequate life span and operation.

 

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 
sheet.

• Never use the internal relay under any load that exceeds 

the rated contact values including the switching capaci-
ties (contact voltage and contact current).

   Otherwise it will impair prescribed performance (insula-

tion failure, contact welding, contact failure) and cause 
burning of the Relay itself.

DIN Rail Adaptor

Shape and size of the base socket 
are slightly different with various 
socket types.

 

DIN RAIL MOUNTING

Set the base socket so that its 
DIN rail adaptor is at the bot-
tom.  Position the upper hook 
at the rear side of base socket 
on the DIN rail and push in 
the lower.  When removing the 
socket, push down the DIN 
rail adaptor utilizing a minus 
screwdriver and pull.

 

WALL MOUNTING

• Install using M4 screw with re-

ferring to the right dimension.

• Install by screw that is securely 

fastened or equivalent means.
