„ Cooling
Provide sufficient space around each SERVOPACK to allow cooling by fan and natural con-
vection.
„ Where mounted side by side
When installing SERVOPACKs side by side, provide at least 10mm (0.4 in.) space between
them and at least 50 mm (2 in.) space above and below them as shown in the figure above.
Install cooling fans above the SERVOPACKs to prevent the temperature around each SER-
VOPACK from increasing excessively and also to maintain the temperature inside the con-
trol panel evenly.
„ Environments in Control Panel
Maintain the following conditions inside the control panel:
• Ambient temperature for SERVOPACK: 0 °C 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
• Altitude of 1000 m max.
