Now connect all signals listed below, items 1 to 10, since at this stage

9.3.1 Removal of the guards
Remove the Plexiglas guards by unscrewing the supporting screws. It
is recommended to remove one guard at a time (i.e. remove the
positive-side guard, connect the positive strings, close the guard and
proceed in the same way on the side for negative voltage) in order to
avoid any accidental contact. (Ref. §9.3.10, §9.3.12, §9.3.13)
