Where mounted side by side
When installing SERVOPACKs side by side, provide at least 10mm (0.4in.) space between
them and at least 50mm (2in.) space above and below them as shown in the figure above. Install
cooling fans above the SERVOPACKs to prevent the temperature around each SERVOPACK
from increasing excessively and also to maintain the temperature inside the control panel even-
ly.
