1.12 To access the instrument

1.13 Modular system

Series S panel meters are designed to create a modular system. This 

modular system allows for addition, replacement or substitution of 

any of the internal modules conforming the instrument. Below is a 

graphic explanation for the position of each module.

Risk of electric shock. Removing the front cover will 

grant access to the internal circuits. Disconnect the 

input signal to prevent electric shock to the operator. 

Operation must be performed by qualified personnel 

only.

You may need to access the inside of the instrument to add or re

-

place internal modules. Use a flat screwdriver to unlock the upper 

clips marked with ‘A’. Then unlock the lower clips marked with ‘B’ and 

remove the front cover. Let the inside of the instrument slide out of 

the housing.
To reinsert the instrument make sure that all modules are correctly 

connected to the pins on the display module. Place all the set into 

the housing, assuring that the modules correctly fit into the internal 

guiding slides of the housing. Once introduced, place again the front 

cover by clipping first the upper clips ‘A’ and then the lower clips ‘B’.
