SECTION 2 INSTALLATION
2.1 Introduction
This section provides all the information required to install the xentra 4900 Continuous
Emissions Analyser. The installer is advised to read this section completely before
commencing installation.
Installation of the xentra requires the use of standard hand tools only.
The analyser is configured for either panel mount or 19" rack mount. If fitted with rack
mount brackets, but without slides, adequate support for the analyser weight must be
provided. The analyser must never be carried or supported by the rack mounting
brackets.
The xentra complies with EN 61010-1 : 1993 which requires that the installation
requirements specified for the analyser include the pollution degree and installation
category for which the analyser is suitable. Pollution degree is concerned with the type
of material which may enter the analyser and degrade the electrical insulation. The
xentra is rated for ’POLLUTION DEGREE 2’ where normally only non-conductive
pollution occurs. Installation category is concerned with the level of over-voltage
transients experienced on the electrical power supply. The xentra is suitable for
’INSTALLATION CATEGORY II’ which is characterised as being local level (ie not
distribution level), appliances and portable equipment with over-voltage impulse
withstand up to 2500 Volts. For further guidance see IEC 664.
Ambient Operating Conditions:
Operating Temperature: 5 to 45ºC / 41 to 113ºF
Storage Temperature: -20 to +60ºC / -4 to +140ºF
Atmospheric Pressure: 79 to 124 kPaa/11 to 18 psia
(for operating altitudes to 2000m)
2.2 Unpacking and Inspection
WARNING
Xentra 4900 analysers weigh up to 22kg (45lb) and care must be taken
when handling. It is recommended that they are lifted with both hands
positioned on either side of the base of the chassis
