Derating Specifications on page 19
Observe the following precautions when you install the SERVOPACK.
 Installation in a Control Panel
• Design the size of the control panel, the SERVOPACK installation location,
and the cooling method so that the temperature around the SERVOPACK
meets the environmental conditions given on the previous page.
• If you install more than one SERVOPACK together, provide space between
any two adjacent SERVOPACKs and install a fan above the SERVOPACKs.
Also, provide space above and below the SERVOPACKs.
 Installation Near Sources of Heat
Implement measures to prevent temperature increases caused by radiant or con-
vection heat from heat sources so that the temperature around the SERVO-
PACK meets the environmental conditions.
 Installation Near Sources of Vibration
Install a vibration absorber on the installation surface of the SERVOPACK so
that the SERVOPACK will not be subjected to vibration.
 Installation in Locations Subject to Corrosive Gas
Implement measures so that corrosive gas does not enter the SERVOPACK.
Although corrosive gas will not immediately affect the SERVOPACK, it may
cause the SERVOPACK or contact devices to fail in the future.
 Other Precautions
• Do not install the SERVOPACK in a location subject to high temperatures,
high humidity, water drops, cutting oil, excessive dust, excessive dirt, exces-
sive iron powder, corrosive gasses, or radioactivity.
• Do not subject the SERVOPACK to freezing or condensation.
• To ensure long-term reliability, use the SERVOPACK at a surrounding air
temperature of 45C or lower.
