Power Barrier, even those which are not used. 16 Commissioning and Hardware Installation Manual, March 2017, A5E

17 Installation Instructions 4 Field installation involves retrofitting various components inside and outside the electronics cabinet. In addition to general hand tools, a power drill and protective drop cloths are desirable. Some components may already be present. 4.1 General Analyzer Shutdown Procedure Back Up the Database If a current database has not been saved, first save a database to a remote device to provide a potential method of reloading if a CAC3 has been replaced or an earlier database needs to be restored to the analyzer. Generally, a database reload will not be needed, though in some cases this may be required. 1. Put the Maxum II in Hold and wait for the cycle to complete. This will provide the quickest restart of the application when power is restored. 2. After the cycle has completed and the analyzer is in Hold: Turn off carrier gas, valve gas, instrument air, and sample flows. Remove power from the unit. WARNING Voltage dangerous to life exists. Failure to follow appropriate safety procedures may result in severe injury or death. Before beginning to work inside the electronics enclosure, the power must be externally removed from the GC. AC power comes directly into the electronics enclosure, so power must be removed and secured/tagged to prevent inadvertent application while work is being performed. 4.2 Maxum Airless/Airbath Model Mounting Locations for SSSI Components The illustration below shows the mounting positions and hardware for component inside the Maxum electronics cabinet. Threaded studs are provided on newer models as shown below. Commissioning and Hardware Installation Manual, March 2017, A5E

Note Keep metal fragments from damaging the electronics. Any procedure where holes are dilled in metal can cause a large number of metal fragments to scatter in the work area. Be very careful to capture all these fragments and keep them from falling onto an electronics board. If this happens, the board is likely to become inoperative and require replacement. Microscopic metal fragments are very dificult to remove from under small electronic components after they have become lodged there. 18 Commissioning and Hardware Installation Manual, March 2017, A5E

19 Installation Instructions 4.2 Maxum Airless/Airbath Model Install paper or a drop cloth taped to the top and back of the cabinet to catch the metal chips from drilling. Adding tape with adhesive side up will help to trap debris. Allow space for the length of the drill bit as it penetrates the metal. (If you forget that last detail the drill bit will wrap the drop cloth around itself and sling the metal shards all over the electronics.) If space allows, a disposable beverage cup can be taped under the drill site. Cover electronic components below the work area with paper or cloth. Find the small pilot dimples on the exterior top of the analyzer cabinet. Use the dimple nearest to the front of the cabinet to drill the pilot hole. This position avoids interference with components mounted on the rear wall of the cabinet. Drill a 10.5mm (3/8 ) pilot hole to accommodate the draw stud. Carefully remove the upper paper from the inside top without spilling metal fragments. Location for Conduit Box Hole Commissioning and Hardware Installation Manual, March 2017, A5E

26 Installation Instructions 4.3 Maxum Modular Oven Model Working Around the IO Cage Two different styles of IO cage may be installed. The earlier cage mounted the IO cards hrizontally. It did not accomodate long cards, so it can be left in place while installing other components. The Operating Position is the normal configuration of the analyzer. The two studs on the bottom rear of the tray slide into two slots on the bracket on the rear wall, and a single captive thumbscrew secures the front of the tray to the upper bracket. The IO tray with IO boards installed can quickly be moved from one position to the other without disconnecting the cables. Analyzer with Horizontal IO Cage Service Position allows the IO tray to be removed from the electronics enclosure and hung up with the IO cards exposed while keeping the IO and I 2 C wiring connected. Two studs on the bottom rear of the tray are inserted loosely into two holes on the front upper bracket. This facilitates testing and maintenance. Service position can only be used with power on if local regulations allow operating with the door open.
