Update 6. Enter QA - Expert mode - Spike check 7. Run spike check 5 times without covers and store results - if outside spec. remedy problem 8. End Numaris and invoke system shut down. 9. De-energize system at alarmbox or switch to “Stand-by” 10. Switch-off 80 amps breaker F1 inside GPA cabinet Discharging hazardous voltage 1. Connect one end of the ground rod to the frame structure of the magnet and with the tip of the ground rod touch the non-insulated gradient leads to discharge any residual electrical current (Fig. 5 / p. 8)

Update NOTE
If after tightening of the split nut a gap remains, remove the split nut. Attach it again, displaced by 1/8th of a revolution. Repeat this procedure until the optimal position of the split nut is achieved. By applying a torque of 8 Nm tighten it
5. Apply loctite to secure the allen screws 6. When the first of the three axes is complete, apply the same procedure to the next axis.

1. Fill out, and if necessary, make a copy of the attached "Completion Protocol" and file it in the corresponding folder. 2. The update must be reported by authorized personnel, either via an intranet application or by automated data transfer (only in countries connected via update handling interface). 3. Take five minutes of your time and answer below questions: Prior to this UI was the torque of the coax connection at the gradient coil within spec. (90 Nm) ? X answer yes or no Y answer yes or no Z answer yes or no Prior to this UI was the torque at the lower section of the gradient cable interface panel within spec (35 Nm)? X answer yes or no Y answer yes or no Z answer yes or no Prior to this UI was the torque at the upper section of the gradient cable interface panel within spec (35 Nm)? X answer yes or no Y answer yes or no Z answer yes or no Meant are all gradient cable joints at the gradient coil and gradient cable interface panel (Fig 7 and Fig 13).
