Converter inspected by HSE (Electrical) and ready to be powered Power Converter connected to the AC network and the responsibility transferred to EPC Power Converter connected to the Water Circuit Control infrastructure validated EIS out-of-chain and interface validated Power converter water interlock operational [WIC] <=> [power converter] interface comissionning Insulation tests on the DC magnets + cables Connection to Magnet Current loop tuning (10 % I. nom) Possible during IST period if: Polarity check (circuit and magnet) • Balisage on magnet Current loop tuning at I. max • Isolated test sector Heat run at I. mag [BIS Interlock / External conditions] <=> [power converter] interface comissionning. Important to consider for EPC: ü ü ü Standard process IST period EPC pre-test (Load disconnected) IST period Hardware commissioning Powering test HWC period OPTIMIZATION with EPC follow-up form Commissioning OR restart tests Range of power converter ( load distribution around the machine) Check if particular sector can be fully isolated for powering test (TT 20/TT 40/…) Balisage in the machine ! (EPC on surface and MSC in underground) Ensure availibility of different services (AC + cooling + WIC + etc…) to maximum anticipated ISTs! Implement in the planning the different possible slots (in function on constraints, buildings, lines, …) 5

To consider for EPC preliminary-tests: (Imag = 0) q q HSE agreement = Start point for EPC pre-tests No current on machine (move lockout to DC) Y T No co-activities around converter locations E F A S Move Lockouts to DC cables (if possible) q q q Plan HSE inspection Availibilities of different services (AC + cooling + WIC + etc…) Plan Hand-over tasks (with EN-EL) PLANNING Plan EPC preliminary tests (up to Uloop) Plan Functional tests with ICS (cvs interlocked on new EIS-PPS) DC DC DC Magnet 6

To consider for IST: (Imag ≠ 0) q Sectorization & balisage (constraints, close area) q Who manage these tasks, & who approve? q SAFETY in these conditions To discuss !!! q Connection to magnet = Start point for IST q Dedicated for low current CURRENT tests (10%. Inom on magnet) q Optimize test sequences (EPC follow-up form to reduce impact of HWC) To consider for HWC (powering tests): q q (Imag ≠ 0) DSO test validated Dedicated for full CURRENT tests (100%. Inom on magnet) Possibility to control converters at same time (independently of location) Optimize test sequences (EPC follow-up form to reduce impact on HWC period) 7

Needs for EPC group: Ø Declare and announce prerequisites and service availabilities in the SPS planning * General service (AC, light, water, wifi) * HV Circuits locked-out by the network separation procedures * Hand-over to TE/EPC (18 k. V departures) * Controls, Ethernet, Interlock system, WIC, BIS * etc… Ø Identify and plan in accordance with ACE, all preliminary tests * DSOs * EIS-PPS * Control tests on EPC equipment (no power) Ø Depending buildings, ADVANCE start dates for IST periods (6 weeks per building) BA 1: BA 2: BA 3: BA 4: BA 5: BA 6: BA 7: SR 2: SR 8: IMPOSSIBLE to advance mid-July 2020 mid-June 2020 from April 2020 July 2020 mid-march 2020 from May 2020 from April 2020 from February 2020 to be analysed Shadow with RF conditioning more flexible Shadow with ABT ISTs more flexible BB 3: BB 4: idem BA 3 mid-February 2020 (TT 40) 2 nd week of April 2020 Important for EPC Ø As much as possible, ANTICIPATE tests of EPC consolidation projects (without power before the IST period) !! Ø Hardware commissioning FOCUS on: * Power tests on SMD/SMQ, Sextupoles and Octupole converters * Restart tests on equipment in operation before LS 2 Ø IST period FOCUS on: * Tests of converters involved in consolidation projects 22

Commissioning follow up form (for EPC equipment): X e.

Safety all along LS 2, IST and HWC: Location of Electrical risks ü All longer, time/period test requests during the long shutdown must be announced for agreement ü Organisation/safety to be discussed in LS 2 C with compensatory measures Authorization from HSE / ACE exemple: Lockout move to DC cables LS 2 only on surface ü Active lockouts (converter responsible) can be moved to DC part (if necessary and possible), and clearly identified (even for SMD/SMQ) ü During LS 2 period, even none powering tests (on single converter), always request green light of ACE ü Before starting any powering tests: • Green light from ACE (during IST) • Green light from OP (during HWC) • Identification of test in progress on all building doors (where is located the equipment) • Local balisage in case of particular circuit test, during IST • Area closed (identified) and controlled by ccc, during HWC IST & HWC on surface and underground ü During IST and HWC periods, for powering tests on converters, request green light from ACE / OP 24
