6.1  Preparation 

A power supply unit is integrated in the NUVOLAS, which needs to be connected to the 
mains. This is the standard power supply. Input voltage ranges between 100 V and 230 V. 
Only use the power supply distributed by A.R.C. Laser GmbH. 

Please  refer  to  the  following  steps  when  preparing  the  device  to  operation  in  order  to 
avoid unnecessary troubleshooting or even possible malfunctions. 

•

  Is the laser connected to the power supply? 

The power supply only has to be connected if the device is switched off. 

•

  Has the door interlock connector for the external interlock been plugged in? 

– or, if 

applicable: has the door interlock contact been connected to the laser? 

•

  Is a fiber or probe still connected? 

•

  Are the fibers and probes free of any damage? 

•

  Is there a sufficient number of protective glasses ready to be used? 

•

  Has the footswitch been plugged in? 

We recommend placing the NUVOLAS on a dry and solid surface. Ensure a stable stand 
for the laser system. 

 

 

A T T E N T I O N  

All warning lights outside the treatment rooms must be switched on as soon as the 
laser starts to operate. The doors have to be marked accordingly, visible from outside 
(with the warning signs).
