12 ACF5000 FTIR ANALYZER SYSTEM | OI/ACF5000-EN REV. A
Safety instructions for handling the FTIR spectrometer
Central unit with electronics module (power supply):
The FTIR spectrometer has an unprotected metal housing that is connected
directly to ground potential via the power cable and is thus classified as
"Safety Class 1 Equipment".
Before fuses are replaced, the device must be disconnected from the power
supply.
To avoid electric shock, the device may not be operated if there is an indica-
tion that any part of the outer surface is damaged.
To protect against fires, only a fuse of the specified type and current rating
may be used.
To protect against electric shock, the protective ground conductor of the
power cable must be connected to ground potential.
CAUTION! The device must not be exposed to any source of the excessive moisture.
The device may not be used in an explosive hazardous atmosphere.
NOTICE Approval from the responsible authorities is required for measurement of
combustible gases.
Laser safety
Under normal conditions, the FTIR spectrometer can be operated completely
safely (Class 1 laser product – see name plate).
Type of laser installed in the interferometer: Class 3B VCSEL laser to
IEC 60825-1 as well as 21 CFR Chapter 1, Subchapter J
Output: max. 3 mW
Wavelength: 760 nm (laser beam invisible to the human eye)
The housing of the interferometer AU3 may not be opened during normal
operation. It contains no user-operated parts.
The housing of the interferometer may be opened only by authorized ABB
service personnel.
Opening the housing of the interferometer AU3 and the interferometer
module in particular can result in contact with laser radiation.
Radiation from Class 3B lasers poses a danger to the human eye both when
viewed directly and if reflected.
