INM MTL 130-0202 Rev 453 INSTALLATIONWARNINGThe weight of this equipment is in excess of 18kg, and the use of mechanicalhandling equipment or assistance from additional personnel is recommendedwhen handling and mounting.3.1 Unpacking and visual checkingTake all standard precautions when opening packages. In particular avoid the use of long bladedcutters. Search packing before discarding it and make sure that all of the components areremoved. Check that all pipe connections have captive seal nuts.3.2 MountingThe analyser is supplied as two separate parts – the panel mounting katharometer/reactorassembly and the control electronics in its own environmental enclosure. The enclosure is un-drilled but is supplied with suitable cable glands. The user may therefore choose the cablingarrangement and drill holes in the enclosure to suit the application.3.3 Electrical connectionsTerminal blocks are provided in the lower part of the enclosure. See diagrams and labels fordetails.WARNINGThis instrument must be installed with a disconnecting switch close to it,within easy reach of the operator and compliant with the relevant parts of IEC60947-1 and IEC 60947-3. It must be marked to indicate this function andshow ON and OFF positions. Wiring should conform to local codes.Only the live conductor has an internal equipment fuse. European regulationsrecommend that fuses be fitted in both the live and neutral of the mainssupply to the instrument.NOTEThe Relay operation and labelling ‘Normal’ relate to “process normal” and not the electricalrest position of the relays, In process normal the relays are energised.3.4 Installation requirements for EMCTo ensure compliance with the European EMC directive certain installation precautions arenecessary as follows:3.4.1 Routing of wiresTo minimise the pick-up of electrical noise all signal wiring should be shielded and routed awayfrom power cables and sources of strong magnetic fields.3.5 Sample conditioningIt is essential that the sample is dried to a water dew point of –10°C (14°F) or lower becausewater will react to some extent with the chlorine as the sample passes through the reactor.The reaction produces oxygen and hydrogen chloride and the effect of the oxygen appearingin second measurement sensor causes the hydrogen value to be reported lower than its truevalue. This is a slow reaction and its extent is dependent upon the sample flow rate and thereactor temperature.
