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 in the figure above, allow at least 100 mm between
and at least 120 mm above and below each SERVOPACK. Allow the space for eyebolts on both sides of the
SERVOPACK.
