Electrical Connections
This chapter details the electrical connections of all the system components
(MX43, modules, additional equipment).
Central Unit Connection
The electrical connections must be carried out by qualified personnel in
compliance with the different directives in force in the country of installation.
The MX43 does not have a start/stop switch.
Certain voltage levels are capable of causing serious injuries or even
death. It is advised to install the material and cabling before applying
live voltage.
As an incorrect or poor installation may cause measurement errors
or system failures, it is necessary to strictly follow all the instructions
in this manual in order to guarantee the proper operation of the
system.
