Servopack Orientation
Install Servopack perpendicular to the wall so that the front panel faces outward. The
front panel is the side to which the Digital Operator is connected.
Cooling
Provide sufficient space around each Servopack to allow cooling by natural convection
or fans as shown in the above diagram.
Adjacent Installation
When installing Servopacks side by side, provide at least 10 mm space between them
and at least 50 mm 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
evenly.
Control Panel Environment Conditions
• Ambient temperature for Servopack: 0 °C to 50 °C
• Humidity: 90% RH or less
• Vibration: 9.8 m/s 2
