       All safety related  codifications, symbols and instructions that appear in this operating manual 
or on the equipment must be strictly followed to ensure the safety of the operating personnel as 
well as the instrument. 

      If all the equipment is not handled in a manner specified by the manufacturer, it might impair the 
protection provided by the equipment .

Product improvement and upgrade is a constant procedure. So for more updated operating information and support, 
Please contact our helpline : +91-9978991474/76/82 or Email at [email protected]             Ver: 2008

=>

 Read complete instructions prior to installation and operation of the unit. 

WARNING

 : Risk of electric shock.

 3) Cable used for connection to power source, must have a cross section of 1mm or greater. These wires 
      should have insulations capacity made of at least 1.5kV.      

 2) To reduce electro magnetic interference, use wire with adequate rating and twists of the same of 
      equal size shall be made with shortest connection.            

 4) When extending the thermocouple lead wires, always use thermocouple compensation wires for wiring 
      for the RTD type, use a wiring material with a small lead resistance (5

Ω

 max per line)and no resistance 

      differentials among  three wires should be present.        

 1) To prevent the risk of electric shock power supply to the equipment must be kept OFF while doing the 
     wiring arrangement. Do not touch the terminals while power is being supplied.  

 5) A better anti-noise effect can be expected by using standard power supply cable for
      the instrument.         

1) This equipment, being built-in-type, normally becomes a part of main control panel and in such case the 
    terminals do not remain accessible to the end user after installation and internal wiring.  

2) Do not allow pieces of metal, wire clippings, or fine metallic fillings from installation to enter the product 
     or else it may lead to a safety hazard that may in turn endanger life or cause electrical shock to the operator.      

3) Circuit  breaker or mains switch must be installed between power source and supply terminal to 
    facilitate power ‘ON’ or ‘OFF’ function. However this mains switch or circuit breaker must be 
     installed at convenient place normally accessible to the operator.     
4) Use and store the instrument within the specified ambient temperature and humidity ranges as 
     mentioned in this manual.

Safety Precautions 

1) Prepare the panel cutout with proper dimensions as show above.
2) Fit the unit into the panel with the help of clamp given.
3) The equipment in its installed state must not come in close proximity to any heating source, 
    caustic vapors, oils steam, or other unwanted process by products.
4) Use the specified size of crimp terminal (M3.5 screws) to wire the terminal block. Tightening the
     screws on the terminal block using the tightening torque of the range of 1.2 N.m.
5) Do not connect anything to unused terminals. 
   

1) The equipment should be cleaned regularly to avoid blockage of ventilating parts.         

2) Clean the equipment with a clean soft cloth. Do not use isopropyl alcohol or any 
    other cleaning agent.
3) Fusible resistor must not be replaced by operator.
