„ Installation
Follow the procedure below to install multiple SERVOPACKs side by side in a control
panel.
SERVOPACK Orientation
Install the SERVOPACK perpendicular to the wall so the front panel containing connectors
faces outward.
Cooling
As shown in the figure above, allow sufficient space around each SERVOPACK for cooling
by cooling fans or natural convection.
Side-by-side Installation
When installing SERVOPACKs side by side as shown above, allow at least 10mm (0.39 in)
between and at least 50mm (1.97 in) above and below each SERVOPACK. Install cooling
fans above the SERVOPACKs to avoid excessive temperature rise and to maintain even tem-
perature inside the control panel.
