4 INSTALLATION AND START UP
This section contains information instructions and warnings that the user must follow by its own security
and to ensure safe operation of the device.
WARNING! Computer MAX regulators are usually connected to equipment containing
capacitors, which remain charged after removing supply voltage. To avoid risk of electric
shock, you must wait at least 5 minutes between the disconnection of the equipment and
handling of the internal components thereof.
Any handling or use of equipment in different way or conditions to that specified by
the manufacturer, may compromise the user safety.
In case that some damage or deterioration signs are detected in the device or a wrong operation is
observed, disconnect the supply voltage and contact CIRCUTOR authorized technical service.
To safely use the Computer MAX 6 and Computer MAX 12 it is important that people installing it or
handling it follow the usual safety precautions stated in the LV or MV Electrical Code Rules of each
Country as well as the different warnings stated in this instruction manual.
4.1 Technical Characteristics
The main technical characteristics of every particular computer MAX 6 and computer MAX 12 device
are printed in the rear label (see fig. 1.2) and are also summarized in the following table.
Supply and measuring circuit
