EL6010 Gas Analyzer in Category 2G Operator’s Manual

42/24-30 EN Rev. 1

Chapter 1

Preparation for Installation

Installation Location Requirements

Installation Location

The gas analyzer should not be mounted outdoors.

Short Gas Paths

Install the gas analyzer as close as possible to the sampling location.

Locate the gas conditioning and calibration assemblies as close as possible to the
gas analyzer.

Adequate
Air Circulation

Provide for adequate natural air circulation around the gas analyzer. Avoid heat
buildup.

Protection from
Adverse Conditions

Protect the gas analyzer from:

•

Cold

•

Direct sunlight and heat

•

Large temperature variations

•

Strong air currents

•

Accumulations of dust and dust infiltration

•

Corrosive atmospheres

•

Vibration

Air pressure range

600 to 1250 hPa

Relative humidity

max. 75 %

during storage and shipping

–25 to +65 °C

EL6010-Caldos17

+5 to +50 °C

EL6010-Magnos106

+5 to +50 °C

Environmental
Conditions

Ambient temperature

in operation

EL6010-Uras14

+5 to +45 °C

Note: The explosion protection is not impaired if the gas analyzer is operated at
temperatures less than +5 °C and down to –20 °C. However in this temperature
range the compliance with the metrological data cannot be guaranteed.
