2. SAFETY
11
1) Potential hazards
There is RF voltage of 3 to 4kV
o–p
in the cabinet of the laser oscillator.
There is 200 VAC power in the relay panel, be careful not to touch the
high voltage.
2) Safety recommendations
When it checks the oscillator and exchange the unit, intercept a main
breaker of the oscillator and the power supply. Lock the breaker to
prevent misconnection and display the sign while working.
Install safety cover after unit replacement or cable connection. Unless
safety cover is installed, never perform operation.
Follow standard industrial safety practices for working with high
voltage.
EXAMPLES
D Do not work on the laser oscillator if you are tired or have taken
medicine.
D Use the buddy system.
D Do not wear anything metal, like a ring, bracelet, watch, belt
buckle, earrings, or keys.
D They might contact high voltage.
D Never stand on a wet surface.
D Do not touch electrical components in the cabinets with both hands
at once. Keep one hand in a pocket.
