■ Orientation
Install the SERVOPACK perpendicular to the wall as shown in the figure.
The SERVOPACK must be orientated as shown in the figure because it is designed to be cooled
by natural convection.

Mounting Holes
Firmly secure the SERVOPACK through the three or four mounting holes provided.
• Installation of Multiple SERVOPACKS
When installing multiple SERVOPACKS side by side in a control panel, provide at least 10 mm
(0.39 in) space between them and at least 50 mm (1.97 in) space above and below them as shown
in the figure above and observe the following installation conditions:
Precautions
Depending on the size of the panel, the temperature inside the
control panel may become higher than the ambient
temperature due to heat generated by internal devices. Design
the control panel size, unit layout, and cooling method so that
the temperature around the SERVOPACK does not exceed
55°C.
Suppress radiation heat from the heating unit and temperature
rise caused by convection so that the temperature around the
SERVOPACK does not exceed 55°C.
Install a vibration isolator underneath the SERVOPACK to
prevent it from receiving vibration.
Corrosive gases do not immediately affect the SERVOPACK
but will eventually cause magnetic contactors or relays in the
reference circuits or main circuits to malfunction. Take
appropriate action to prevent corrosive gases.
Avoid installation in hot or humid places, or where excessive
dust or iron powder is present in the air.
