GENERAL
IMPORTANT
SAFETY INSTRUCTIONS
WIRING AND INSTALLATION OF THIS APPARATUS
The following safety instructions apply specifically to all EU member states. They should be
strictly adhered to in order to assure compliance with the Low Voltage Directive. Non-EU
states should also comply with the following unless superseded by local or National
Standards.
1. Adequate earth connections should be made to all earthing points, internal and external,
where provided.
2. After installation or troubleshooting, all safety covers and safety grounds must be replaced.
The integrity of all earth terminals must be maintained at all times.
3. To ensure safe operation of this equipment, connection to the mains supply should only
be made through a circuit breaker which will disconnect all circuits carrying conductors
during a fault situation. The circuit breaker may also include a mechanically operated
isolating switch. Circuit breakers or switches must comply with a recognized standard
such as IEC947. All wiring must conform with any local standards.
4. Where equipment or covers are marked with the symbol to the right,
hazardous voltages are likely to be present beneath.These covers should
only be removed when power is removed from the equipment — and then
by trained service personnel only.
5. Where equipment or covers are marked with the symbol to the right, there
is a danger from hot surfaces beneath. These covers should only be
removed by trained service personnel when power is removed from the
equipment. Certain surfaces may remain hot to the touch.
6. Where equipment or covers are marked with the symbol to the right, refer
to the Instruction Manual for instructions.
7. Further graphical symbols used in this product:
All graphical symbols used in this product are from one or more of the following standards:
EN61010-1, IEC417, and ISO3864.

07/2006 OPERATING AND MAINTAINING THIS APPARATUS
Operating and maintaining this apparatus
This instrument has left the factory in compliance with all applicable safety regulations.
To maintain this operating condition, the user must strictly follow the instructions and consider
the warnings in this manual or provided on the instrument.
Before switching on the instrument, verify that the electrical supply voltage matches the
instrument´s operating voltage as set in the factory.
Any interruption in the instrument´s ground line, whether inside or outside the instrument, or
removal or interruption of its ground line connection, could result in hazardous operating
conditions. Intentionally interrupting the instrument´s protective ground is strictly prohibited.
Opening cover panels could expose voltage-carrying components. Connectors may also be
under voltage. The instrument must be disconnected from all electrical supplies before
attempting any calibrations, maintenance operations, repairs or component replacements
requiring opening of the instrument. Any calibrations, maintenance operations, or repairs that
need the instrument to be opened while connected to electrical supplies should be subject to
qualified technicians familiar with the hazards involved only!
Use only fuses of the correct type and current ratings as replacements. Using repaired fuses
and short circuiting of fuse holders is prohibited.
Observe all applicable regulations when operating the instrument from an auto-transformer
or variac.
Substances hazardous to health may emerge from the instrument‘s exhaust.
Please pay attention to the safety of your operation personnel. Protective measures must be
taken, if required.

INTENDED USE STATEMENT / SAFETY SUMMARY / AUTHORIZED PERSONNEL
Intended use statement
MLT and CAT200 series gas analyzers/analyzer modules are intended to be used as
analyzers for industrial purposes.They must not be used in medical, diagnostic or life
support applications, and no independent agency certifications or approvals are to be
implied as covering such applications!
Safety summary
If this equipment is used in a manner not specified in these instructions, protective
systems may be impaired.
Authorized personnel
To avoid loss of life, personal injury and damage to this equipment and on-site property,
do not operate or service this instrument before reading and understanding this
instruction manual and receiving appropriate training. Save these instructions.
ELECTRICAL SHOCK HAZARD !
Do not operate without covers secure. Do not open while energized. Installation requires
access to live parts which can cause death or serious injury.
For safety and proper performace this instrument must be connected to a properly
grounded three-wire source of power.
TOXIC GASES !
This unit’s exhaust may contain toxic gases such as sulfur dioxide.
These gases can cause serious injuries.
Aviod inhalation of the exhaust gases at the exhaust fitting.
Connect exhaust outlet to a safe vent. Check vent line and connections for leakage.
Keep all fittings tight to avoid leaks. See section 14 for leak test information.

EXPLOSION HAZARD !
Do not operate nor install these instruments in hazardous areas without
additional measures!
MLT 2 and CAT 200 -- HEAVY INSTRUMENTS !
The analyzer variations MLT 2 and CAT 200 intended to be wall
mounted and/or outdoor installed weigh up to 35 kg resp. 70 kg, depending
on included options!
Use two person and/or suitable tools for transportation and lifting these
instruments!
Take care to use anchors and bolts specified to be used for the weight of
the units!
Take care the wall or stand the unit is intended to be installed at is solid
and stable to hold the units!
HIGH TEMPERATURES !
While working at photometers and/or thermostated components inside the
analyzers hot components may be accessible!
The electrochemical O2-sensor contains electrolyte which is caustic and
can cause serious burns to skin. Do not ingest contents of sensor !
CAUSTIC !
Tampering with or unauthorized substitution of components may adversely affect the
safety of this instrument. Use only factory approved components for repair.
Because of the danger of introducing additional hazards, do not perform any unauthorized
modification to this instrument!

Gases and Gas Conditioning (Sample Handling)
GASES AND GAS CONDITIONING (SAMPLE HANDLING)
Supplying explosive gases is not permitted !
EXPLOSION HAZARD !
Supplying flammable gases of concentrations above 25 % of lower
explosion limit (LEL) we recommend to utilize one or more of the following
measures:
•Purging the housing with inert gas
• Internal tubing with stainless steel
• Flame arrestors at gas input and output fittings
• Intrinsically safe paramagnetical or thermal conductivity sensors
• Purge gas must be conditioned:
Take care for purge gas temperature: Purge gas should have the same temperature as
ambient temperature of the analyzer but NOT below 20 °C and above 35 °C! Otherwise
it must be cooled or warmed up before let in into the instrument!
Purge gas should be instrumental / synthetic air (free of oil, no corrosive, toxic or flammable
gas componets) or nitrogen depending on application.
Take care of the safety instructions applicable for the gases (sample
gases and test gases) and for the gas bottles containing these gases!
Before opening gas paths they must be purged with ambient air or
neutral gas (N2) to avoid hazards caused by toxic, flammable,
explosive or harmful to health sample gas components!
Flammable gases must not supplied without additional protective
measures!
It is prohibited to supply explosive gases!
