3 Installation
3.1 Unpacking your unit
Unpack the X1 external power supply and store the packaging for future transportation. Be careful when lifting the X1 as the unit
is heavy (over 20kg). Get someone to help you if necessary. When unpacking and installing the X1, take care not to damage the
high quality surface treatments.
3.2 Positioning your unit
When delivered from factory, the X1 external power supply's four feet sit on elastomer rings, ensuring both scratch-protection for
the base on which the unit sits, as well as safe anti-slipping unit positioning.
But a more advanced vibration-channeling mechanical coupling can be implemented, thanks to the steel spikes and the polymer
support discs provided with the X1. To use this optimal coupling, simply go through the following steps:
1. Place the X1 unit on a stable base at its approximate final position, for instance in your preferred audio rack. Make sure
cooling air is able to freely flow around the unit.
2. Gently lift the unit's corners and insert a support disc under each foot. The foot's elastomer ring should disappear in the
support disc's groove when properly placed. Carefully check all four feet perfectly fit in each support disc before pursuing
any further. The unit should stably rest on its feet at that point.
3. Unscrew the four top covers from the X1's shafts with the provided suction cup. Be careful not to scratch their delicate
finish.
4. Insert the adjustment spikes into each adjustment shaft.
5. Softly screw clockwise each adjustment spikes into the shaft with the provided screwdriver, until any resistance is felt (just
before the unit's corner starts to lift).
6. Then screw clockwise each spike by the same amount (for instance two full turns).
7. If the base is flat, the unit should be stable and horizontal. If not, correct the unit's stability and horizontality by turning
clockwise or anti-clockwise the required spikes.
8. If no CH Precision unit is to be stacked on top of the X1, screw the four top covers back. Otherwise, screw the four
polymer stacking caps instead, and gently lay down the unit to be stacked on top of it. Be very careful that both units are
perfectly aligned in order not to scratch the X1's top plate with the other unit's feet. Repeat steps 3 to 8.
