confirm its operational range as indicated below:

  85 – 264V AC rating: 85 – 264V, 47 – 66 Hz, approx. 2 – 3VA
    24V DC rating: 24V ±10%, approx. 2W

 

GENERAL PRECAUTIONS

• 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, 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     

(23 to 131°F) with relative humidity within 0 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.

• Install lightning surge protectors for those wires connect-

ed to remote locations.  For 24V DC power supply line, 
choose a surge protector with its maximum surge voltage 
40V or less between lines.  Recommended M-System mod-
el: MDP-D24.
