3. Installation issues - update, July 2006 A.Fabich 3 ACAD layout file EDMS versions obsolete (cancelled) New version available within EDMS/CDD https://edms.cern.ch/cdd/plsql/c4w_02.drawing_info?num=PS_XXMER0001 This is an active document. It is permanently updated. Recently incorporated/updated items: Cryogenic installations: DVB, heater, lines Passages TT2/TT2A Distribution boxes: Electrical power (220V/400V) Ethernet Several cuts/views Following soon: Details of control/electronic racks in TT2, horizontal platforms Beam line elements Beam monitors Quadrupoles Transport study is on-going: false floor, ramp...

4. Installation issues - update, July 2006 A.Fabich 4 Changed position of racks OLD layout NEW proposal ~1.4 m Is this acceptable? Power distribution box ETHERNET

5. Installation issues - update, July 2006 A.Fabich 5 Electrical power supply (220/400 V) Received response from the groups responsible for mercury loop, optical diagnostics, cryogenics, particle detectors and beam diagnostics. Sufficient input for releasing installation request. The power outlets will be installed in TT2 next to the racks (see ACAD drawing). Installation scheduled for October 2006 “Open” issues: Optical diagnostics asked for 110 Volt Is this really required? Can it be provided by the Hg loop system, which has already internally 110V supplies? Hg loop Power cable (not conform with IS23) can be adapted in place at CERN. US plugs can be exchanged/adapted in place at CERN.
