1.15 Modular system
M Series 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.
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’.
Important - If your instrument was delivered with the IP65 front
seal option, accessing the inside of the instrument will permanently
break the IP65 seal on the areas of clips ‘A’ and ‘B’.
