Side-by-side Installation
When installing servo amplifiers side by side as shown in the figure above, allow at
least 0.39in. (10mm) between and at least 1.97in. (50mm) above and below each
servo amplifier. Install cooling fans above the servo amplifiers to avoid excessive
temperature rise and to maintain even temperature inside the control panel.
