MAINTENANCE 

 

CAUTION

 : BEFORE OPENING the unit, disconnect the power source from the mains. Voltages are high and 

dangerous inside the machine. 
 
In spite of their robustness, NEXUS power  sources require some regular maintenance.  
Once every 6 months (more often in dusty surroundings) : 

-

 

the machine must be blown through with dry, oil free compressed air 

-

 

check for continuity all electrical connections. 

-

 

Check all cable connections, including ribbon cables.
