Safety Protection Measures For Users - Panasonic LP-V Series Operation And Maintenance Manual

Safety Protection Measures for Users

This product falls into Class 4 laser (marking laser) and Class 2 laser (guide laser) based on the classifications of the Safety
of laser products by IEC60825-1 / FDA standards 21 CFR 1040.10 and 1040.11 / JIS C 6802.
Perform the safety protection measure shown below before using the system.
For more detail instruction, refer to each of the standard.
Moreover, there is a case where related regulations are set for using the laser product depending on a country and a
region. When use this product, follow these regulations.
⿎ Construction of interlock system
For operating this product, construct the protective enclosure enclosing the range of the laser radiation for protecting
the exposure caused by the reflection of the laser radiation from the marking object or the surrounding objects, and also
construct the interlock system at the same time. Additionally, install the control part that is not to exposure to the laser
beam. Refer to "Construction of Interlock System" (P.31) for details.
WARNING
⿎ Wearing protective goggles
For protection eyes of an operator, make it mandatory to wear goggles against laser beam in the laser control area.
Use the laser protective goggles or glasses applicable for wavelength of the specific to the marking laser and appropriate to
working conditions.
For this product, use the laser protective goggles or glasses which meet the following requirements.
• For LP-400 series: The goggles or glasses that have Optical Density (OD) of more than 6 at wavelength 9300 nm to
10600 nm (9.3 to 10.6 micrometers).
• For LP-V/LP-W series: The goggles or glasses that have Optical Density (OD) of more than 6 at wavelength 1060 nm to
1070 nm (1.06 to 1.07 micrometers).
• Through the goggles or glasses, the laser radiation indicator should be recognized.
• ANSI Z136 and CE certified laser safety goggles or glasses
The protective goggles can momentarily protect the eyes against the scattered beam. Never look at the direct beam or
reflected beam even when the goggles are used.
⿎ Protective enclosure
In order to prevent exposure to laser beam accidentally reflected from the marking object or from its circumferential areas,
place a protective enclosure so that it can enclose the area in the range of laser radiation.
Construct the enclosure with proper reflectance, durability and thermal resistance materials that does not transmit a
wavelength of the marking laser.
Recommended material for the enclosures:
• For LP-400 series: Metals such as iron, aluminum, or stainless steel, or acrylic resins. For acrylic plate, its thickness
should be more than 3mm and it is recommended to use the plate that has a color to reduce the secondary radiation
beam such as spark during the lasing.
• For LP-V / LP-W series: Metals such as iron, aluminum, or stainless steel.
Design the enclosure not to leak the laser beam from the joint parts.
Example of the joint parts:

Danger of laser exposures
• Construct a system for re-pumping the laser manually as safety protection
measures after stop of the laser radiation.
