  Mechanical Installation

 

This chapter details the mechanical installation of MX 43 and the digital 

modules.

 

MX 43 Central Measurement Unit 

 

Location

 

The MX43 shall be installed in premises without explosive atmospheres, away 
from direct sunlight exposure, and protected from humidity, dust, and 
temperature variations. It shall preferably be located in a place under 
supervision (guardhouse, control room, or instrument room, for example). 

Attachment of the wall enclosure 

 

Access to the central unit must be ensured in the front in order to facilitate 
adjustments, monitoring, and cabling. A space of 400 mm is necessary in front 
of the MX43 for opening the door. 

 

 

 

(*) rear fixing legs included.
