Take the keys which are required to set up the interlock (key box in control room), go to room 501, open rack 22, the uppermost crate and press the reset button in a unit called "Experiment HERA-B" (see Fig. 1). If this is done continue with b).

In order to reset you just have to press one of these push-buttons.
Now you can switch on the corresponding power
distribution frames. The big red switch has to be grounded (green 0) and then switched on which
