GENERAL
1. General
◆ The following general safety precautions must be observed during all phases of operation,
service and repair of this instrument !
Failure to comply with these precautions or with specific warnings elsewhere in this manual
violates safety standards of design, manufacture and intended use of this instrument !
Failure to comply with these precautions may lead to personal injury and damage to this
instrument !
◆ Fisher-Rosemount GmbH & Co. does not take responsibility (liability) for the customer´s
failure to comply with these requirements !
◆ Do not attempt internal service or adjustment unless other person, capable of rendering first
aid and resuscitation, is present !
◆ Because of the danger of introducing additional hazards, do not perform any unauthorized
modification to the instrument !
Return the instrument to a Fisher-Rosemount Sales and Service office for service or repair
to ensure that safety features are maintained !
◆ Instruments which appear damaged or defective should be made inoperative and secured
against unintended operation until they can be repaired by qualified service personnel.

GENERAL / GASES AND GAS CONDITIONING (SAMPLE HANDLING)
Operating personnel must not remove instrument covers !
Component replacement and internal adjustments must be made by qualified
service personnel only !
Read all operation manuals before attempting to operate with the instrument !
Be sure to observe the additional notes, safety precautions and warnings given
in the individual operation manuals (e. g. platform, analyzer modules and
I/O-modules) !
Do not operate the instrument in the presence of flammable gases or explosive
atmosphere without supplementary protective measures !
At photometer or heated components there could be exist hot components !
2. Gases and Gas Conditioning (Sample Handling of analyzer modules)
Be sure to observe the safety regulations for the respective gases
(sample gas and test gases / span gases) and the gas bottles !
Inflammable or explosive gas mixtures must not be purged into the instrument
without supplementary protective measures !
To avoid a danger to the operators by explosive, toxic or unhealthy gas
components, first purge the gas lines with ambient air or nitrogen (N

SUPPLY VOLTAGE
3. Supply Voltage
The socket outlet shall be installed near the equipment and shall be easily
accessible to disconnect the device from the socket outlet.
Verify whether the line voltage stated on the instrument (LFM 01) or power supply
agrees with that of your mains line!
Be sure to observe the safety precautions and warnings given by
manufacturer of power supply !
◆ NGA 2000 platform is a Safety Class 1 instrument
The platform is provided with a protective earth terminal.
To prevent shock hazard, the instrument chassis and cabinet must be connected
to an electrical ground. The instrument must be connected to the AC power
supply mains through a three-conductor power cable, with the third wire firmly
connected to an electrical ground (safety ground) at the power outlet.
If the instrument is to be energized via an external power supply, that goes for the
power supply too.
Any interruption of the protective (grounding) conductor or disconnection of the
protective earth terminal will cause a potential shock hazard that could result in
personal injury. Deliberate disconnection is inadmissible / prohibited !
Verify that the position of input voltage switch of the 10 A power supply agrees
with that of your mains line (Fig. 20-3 and 1-4) !
Verify correct polarity for 24 V dc - operation !

4. Instrument specific notes for the user
The installation site for the instrument has to be dry and remain above freezing
point at all times.
The instrument must be exposed neither to direct sunlight nor to strong sources
of heat. Be sure to observe the permissible ambient temperature !
For outdoor sites, we recommend to install the instrument in a protective cabinet.
At least, the instrument has to be protected against rain (e.g., shelter).
Free flow of air into and out of the platform (ventilation slits) must not be hindered
by nearby objects or walls !
Use only from our factory optional delivered cables or equivalent shielded cables
to be in agreement with the CE - conformity.
The customer has to guarantee, that the shield is be connected bothsided.
Shield and connectors housing have to be connected conductive.
Sub.-min.-D-plugs/sockets have to be screwed to the analyzer.
By using of optional delivering terminal strip adapters the analyzer is not be in
agreement with the CE - conformity. In this case CE - conformity is to be declared
by customer as “manufacturer of system”.

Operating personnel must not remove instrument covers !
Component replacement and internal adjustments must be made by qualified
service personnel only !
Always disconnect power, discharge circuits and remove external voltage
sources before troubleshooting, repair or replacement of any component !
Any work inside the instrument without switching off the power must be
performed by a specialist, who is familiar with the related danger, only !
In case of exchanging fuses the customer has to be certain that fuses of specified
type and rated current are used. It is prohibited to use repaired fuses or defective
fuse holders or to short-circuit fuse carriers (fire hazard).

5.1 Electrostatic Discharge
The electronic parts of the analyzer can be irreparably damaged if exposed to electrostatic
discharge (ESD).
The instrument is ESD protected when the covers have been secured and safety precautions
observed. When the housing is open, the internal components are not ESD protected anymore.
Although the electronic parts are reasonable safe to handle, you should be aware of the following
considerations:
Best ESD example is when you walked across a carpet and then touched an electrical grounded
metal doorknob. The tiny spark which has jumped is the result of electrostatic discharge (ESD).
You prevent ESD by doing the following:
Remove the charge from your body before opening the housing and maintain during work with
opened housing, that no electrostatic charge can be built up.
Ideally you are opening the housing and working at an ESD - protecting workstation.
Here you can wear a wrist trap.
However, if you do not have such a workstation, be sure to do the following procedure exactly:
Discharge the electric charge from your body. Do this by touching a device that is grounded
electrically (any device that has a three - prong plug is grounded electrically when it is plugged into
a power receptacle).
This should be done several times during the operation with opened housing (especially after
leaving the service site because the movement on a low conducting floors or in the air might cause
additional ESDs).

Introduction
This operation manual informs you about the platform, which is used for accommodating
analyzers or analysis modules of the NGA 2000 series (19", 3 HU, IP 20-housing).
Platform
This housing, together with the operator interface and the built-in controller board ACU 02,
represents the platform for analyzers of the NGA 2000 series.
EMC-Housing
Should the housing be used as an EMC-assembly carrier for non-EMC analysis modules, please
be aware that the installation differs from the description given in this manual. The following
changes must be taken into consideration:
1. The 19" operator interface (chapter 1.1) will be substituted by two 1/2 19" blind front panels.
Each blind front panel can be dismounted separately by removing the respective screws
(6 for each panel).
2. The controller board ACU 02 (chapter 1.3.4) will be replaced by a bulkhead plate.
3. Only rear-panel modules using network can be built-in in this housing.
Modules which need the ICB-bus can not be connected, because the ACU 02 board is not
installed.
4. The operation of built-in analyzer module and any additional rear-panel modules must be
carried out via a "true-type" platform or a superior analyzer.

1. Technical Description
The basis for analyzers of the NGA 2000 series is a 19", 3 HU housing of IP 20 protection class.
The instrument can be delivered as table top or rack mountable unit.
The platform contains all components necessary for operating the analyzer and can be used as
a "stand alone" analysis instrument when combined with an analyzer module and an Input/Output
(I/O) module, or it can be configured as a system when equipped with several analyzer and I/O
modules.
The conceptional design is depicted in the block diagram below (Fig. 1-1).
