To remove the power supply, take the slotted-head screwdriver and unscrew the two retainers located at the side (Figure 2). By pulling
on the handles towards you the power supply will swing out on its support frame. Make sure to pull carefully and with a firm grip, as the
power supply is heavy, especially when equipped with UPS-option. Now unscrew the two slotted-knurled screws in an alternating manor
to avoid tilting the power supply inside the frame (Figure 3). Sometimes a firm pull is needed to completely remove the power supply
from its support frame.

Now replace the power supply and reassemble in reverse order, tie down the internal mains cable on the handle.
4.2 Forced air cooling
The crate offers an internal forced air cooling with temperature dependent speed regulation by the crate controller. The fresh air intake is
on the bottom, for proper ventilation it needs to be sure that the airflow is not blocked. Further it is recommended to cover unused
module slots with blind front panels to provide optimal airflow and cooling performance.
