Installation method:
When installing multiple SERVOPACKs side by side in a control panel, observe the fol-
lowing installation method:
Fan
50 mm or more
Fan
30 mm or more 10 mm or more
Fan
50 mm or more
a) Install SERVOPACK perpendicular to the wall so that the front panel (digital operator
mounted face) faces outward.
b) Provide sufficient space around each SERVOPACK to allow cooling by fan and natu-
ral convection.
c) 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 in-
side the control panel evenly.
d) Maintain the following conditions inside the control panel:
• Ambient temperature for SERVOPACK: 0 to 55°C
• Humidity: 90%RH or less
• Vibration: 4.9 m/s 2
• Condensation and freezing: None
• Ambient temperature to ensure long-term reliability: 45°C or less
