4.4.1 Where Mounted Side by Side
When installing FSP Amplifiers side by side, provide at least 10 mm (0.4 in) space
between them and at least 50 mm (2 in) space above and below them as shown in the
figure above. Install cooling fans above the FSP Amplifiers to prevent the
temperature around each FSP Amplifier from increasing excessively and also to
maintain the temperature inside the control panel evenly.
