WIRING :

 The probe and its corresponding wires should never be installed 

in a conduit next to control or power supply lines. The electrical wiring 
should be done as shown in the diagram. The power supply circuit should 
be connected to a protection switch. The terminals admit wires of upto 
2.5sq mm.

WARNING :

  Improper wiring may cause irreparable damage and personal 

injury. Kindly ensure that wiring is done by qualified personnel only.

Maintenance :

 Cleaning :  Clean the surface of the controller with a soft 

moist cloth. Do not use abrasive detergents, petrol, alcohol or solvents.

Fixing and dimensions of panel models :To fix the unit, slide the side lock

   as per the position shown in the figure. Move the side 

lock in the direction of the arrow, it permits to move the fastener in the opposite 
direction of the arrow.

Fit the screw in the side lock in direction of the arrow to 

hold the controller in the panel.

Installation 

Controller 

Controller  should  be  installed  in  a  place  protected  by  vibration,  water  and 
corrosive gasses and where ambient temperature does not exceed the values 
specified in the technical data.

Probe

To give a correct reading, the probe must be installed in a place protected from 
thermal influences, which may affect the temperature to be controlled.
