Before switching on UltraGROSS (when coming from a storage room), allow the
instrument to reach operating environment conditions (at least half an hour).
For letters that refer to unit codes, see chapter 1.3.1.
Before following these instructions, pull out the green profile from the crosspiece of the unit.
Once all the parts have been installed on the crosspiece, cut the green profile to measure and put it back into
the crosspiece.

The shield block is placed in the middle, below the control terminal of the unit. The unit is shipped with the
shield blocked, as indicated in the figure below. When blocked, you will see two black overlapping bars.
To unlock the shield, use an 8mm Allen wrench like the one supplied with the unit.
