2.3.3 Orientation of and installation space for the SERVOPACK
The SERVOPACK must be installed vertically and sufficient space must be provided around
them for better cooling efficiency, as shown below.
Fig. 2.6 SERVOPACK’s orientation and space
• All SERVOPACKs are designed so as to have their heat sink exposed to the outside.
• For the outside dimensions of and installation space for the SERVOPACKs, see the rele-
vant outline drawings given in the General Documentation - Hardware.
• The allowable temperature range of the air draft against the SERVOPACK is 0-45 ℃ at
the heat sink (outside) and 0-55 ℃ inside.
• Apply sealing agent to the mounting screw areas of the SERVOPACK to prevent oil
from entering inside.
• The SERVOPACK has a built-in fan as shown in Fig. 2.6.
• To prevent the SERVOPACK from overheating, arrange other units and devices such
that the required space is provided over and under the SERVOPACK.
• If an air stirring fan is installed in a panel, the fan must be oriented such that the air does
not directly hit the SERVOPACK (to prevent the SERVOPACK from collecting more
dust).
A space must be provided to the right and left of each SERVOPACK as follows:
