 WARNINGS 

 

If one transformer is used to supply both the μC

2

SE and the accessories, all the G0 terminals on the various controllers or the various 

boards must be connected to the same terminal on the secondary, and all the G terminals to the other terminal on the secondary, so as to 
avoid damaging the instrument; 

 

For use in residential environments, use shielded cable (two wires + shield earthed at both ends, AWG 20-22) for the tLAN connections 
(EN 55014-1); 

 

Avoid short-circuits between V+ and GND so as not to damage the instrument. Perform all the maintenance and installation operations 
when the unit is not connected to the power supply; 

 

Separate the power cables (relay outputs) from the cables corresponding to the probes, digital inputs and serial line; 

 

Use a transformer dedicated exclusively to the electronic controllers for the power supply. 

 

Protection against electric shock and maintenance warnings 

The system made up of the control board (MCH200005*) and the other optional boards (MCH200006*, MCH200485*, MCHRTF****, CONVONOFF*, 
CONV0/10A*, EVD000040*) constitute a control device to be integrated into class I or class II appliances. The class of protection against electric 
shock depends on how the control device is integrated into the unit built by the manufacturer. Disconnect power supply before working on the board 
during assembly, maintenance and replacement. The protection against short circuits due to faulty wiring must be guaranteed by the manufacturer of 
the appliance that the controller will be fitted on.
