2.3 Electrical
safety
WARNING!
Electricity can be a danger to health and life. Immediate
medical assistance must be sought following contact with
dangerous voltage.
The controller contains components carrying dangerous
voltages. Do not open or repair the controller. Do not operate a
controller with damaged housing.
Prior to connecting the power supply cable, ensure that the supply voltage is within
the range given at the AC or DC supply socket of the controller.
The AC power supply cable has to be disconnected before replacing the fuse at
the power supply of the controller. Accumulator terminals may never be shorted or
come into contact with the housing of the controller.
Applicable national safety regulations governing the use of electricity must be
followed. Electrical supply and earthing must be carried out in accordance with
applicable national regulations.
2.4 Laser
safety
WARNING!
The controller contains a laser source. Caution, the laser
radiation is invisible! The controller is classified as a class 1M
laser product.
The following label is attached close to the fibre connector(s) on the controller:
Attached connections:
The laser emits continuously modulated laser radiation at a wavelength of 1550
nm. The modulation frequency is between 500 Hz and 500 MHz. The maximum
average power is 110 mW, and the maximum peak power is 200 mW.
The accessible laser radiation represents no danger for the human eye or skin
assuming that:
the radiation is not focused by optical instruments like magnifying glasses,
lenses or microscopes and
the end of an optical fiber or cable is not approached closer than 10 cm to the
eye or skin.
With optical instruments or during direct approach of the optical fibre to the human
body, laser radiation can generate heat that damages the skin or the cornea of the
eye. Such damages are wet bulges, cataract and burnings of cornea and skin In
the case of eye damage, medical assistance must be sought immediately.
National regulations on laser safety have to be considered during installation and
operation of the controller.
The controller must be switched off before directly viewing on fibre ends, splices or
optical fibre connectors with or without optical instruments.
Use only CE marked fibre-optic microscopes equipped with a 1550 nm DIR LB3
laser safety filter in accordance with EN 207.
