1.2 HIGH VOLTAGE
Fig.1.2(a)-(j) show the position of high voltage in oscillator.
1) Potential hazards
There is RF voltage of 3 to 4kVo-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
• Do not work on the laser oscillator if you are tired or have
taken medicine.
• Do not wear anything metal, like a ring, bracelet, watch,
belt buckle, earrings, or keys.
• They might contact high voltage.
• Never stand on a wet surface.
• Do not touch electrical components in the cabinets with
both hands at once. Keep one hand in a pocket.
