Injury, death, loss of property, fire, electric shock, malfunction, reduced performance & machine life, and critical failures can result from not reading, understanding, and following the Operation Manual.
This applies in particular to activities on the electric equipment, which must only be performed by qualified . For all activities concerning installation, set-up, start-up, operation, modifications of conditions and methods of operation, maintenance, inspection and repair, the switch-off procedures that may be provided in the Operation Manual must be observed.
There are many hazards to be aware of when working with our machines. You will be dealing with 110V AC 60Hz power that can deliver up to 20A (it only takes 0.5A to kill you) across the entire Thunder Laser USA lineup.
The Nova series machines with water-cooled DC excited glass tubes utilize a high voltage DC power supply that is capable of outputting 30,000V DC at 30mA and more. The HVLPS Output (big red wire) should NOT be metered. That wire is big, red, and scary for a reason.
The Nova and Odin series have 2 DC power supplies: a 24VDC for the electronics, lighting and signaling, etc..., and a 36V DC LVPSU dedicated to the X and Y axis motors.
The Thunder Laser machines outfitted with air-cooled RF excited metal tubes will not have a 30KVDC HVLPSU. The RF tubes are powered by a 48V DC LVPSU.
Besides the risk of electrocution, you must be mindful of the motion control components, peripherals, etc... as well as the laser beam itself. The moving parts of these systems can injure, pinch, trap, and even kill you so pay attention and, if you are not confident (or competent) to perform any of these task, you should consult someone who is.
