Environmental Conditions
• Ambient temperature for SERVOPACKS: 0 to 55°C
• Humidity: 90% RH or less
• Vibration: 0.5G (4.9 m/s
• Condensation and freezing: None
• Ambient temperature (or in-panel temperature) to ensure long-term reliability: 45°C or
less
Installation Method
D Install the SERVOPACK perpendicular to the wall so that the front panel faces outward (ME-
CHATROLINK communication connector mounting surface) .
D Provide sufficient space around each SERVOPACK to allow for cooling by fan or natu-
ral convection.
D When installing SERVOPACKS side by side, install cooling fans above the SERVOPACKS
to prevent the temperature around each SERVOPACK from increasing excessively and also
to maintain an even temperature inside the control panel.
