Safety
6 PowerLine E Air
1.4.2 Danger of laser radiation
A laser without any special protective unit belongs to safety class 4. A laser beam is invisible at a
wavelength of 1064 nm. If the positioning laser is activated (wavelength 675 nm, red laser beam),
the laser beam is visible.
The PowerLine E Air laser head corresponds to safety class 4.
The 19" plug-in for electrical components corresponds to safety class 1 due to its safety equipment.
The safety equipment consists of a metal tube and an adapter block or a fiber terminal box. The
safety equipment comprises the following:
–
In the case of the PowerLine E Air 10, the metal tube is permanently connected with the diode
module via an adapter block.
– In the case of the PowerLine E Air 25/ 30, the metal tube is permanently connected with the
fiber terminal box under which the fiber coupling of the diode modules are located. The diode
modules protrude into the fiber terminal box.
This equipment is intrinsically safe and requires no special safety precautions, since no hazardous
laser emissions are generated.
Danger
1
The 19" plug-in for electrical components corresponds to safety class 4 as soon as the safety
equipment (metal tube with adapter block or fiber terminal box) is disassembled, e.g. when a diode
module is changed. In this state, all corresponding laser protection measures can be taken.
1.4.3 Alignment laser (optional)
This is a laser diode of hazard class 2. According DIN EN 60825 the eyes are protected by the
natural eyelid reflex. The alignment laser radiation is not dangerous to the skin.
Warning
1
Never stare, either directly or with an optical device, into the beam of the alignment laser!
1.5 Other dangers
1.5.1 Ultraviolet radiation
Warning
1
The metal vapour plasma which emerges when welding and marking certain metals with a laser
beam emits intense invisible ultraviolet radiation which can cause severe damage to the eyes and
the skin!
The laser protective goggles for 1064nm according to DIN EN 207 or EN 208 are not suitable to
protect the eyes from this ultraviolet radiation. Special goggles which in addition to the wavelength
also protect the eyes against ultraviolet radiation are commercially available.
