3 SERVOPACK Specifications and Dimensional Drawings
3-6
Orientation
Install the SERVOPACK perpendicular to the wall as shown in the figure. The SERVOPACK must be
oriented this way because it is designed to be cooled by natural convection or a cooling fan.
Secure the SERVOPACK using two to four of the mounting holes. The number of holes depends on the
capacity.
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 10 mm (0.39
in) between and at least 50 mm (1.97 in) above and below each SERVOPACK. Install cooling fans
above the SERVOPACKs to avoid excessive temperature rise and to maintain even temperature inside
the control panel.
Environmental Conditions in the Control Panel
Ambient Temperature:0 to 55
°C (32 to 131° F)
Humidity: 90% RH or less
