Σ-Series DR2 Servopack is a rack−mounted type ser-
vo controller.
Incorrect installation will cause problems. Always ob-
serve the installation instructions described in the next
page.
Storage:
When the Servopack is to be stored with the power cable disconnected, store it in the
following temperature range:
Between −20°C and 85°C
Installation sites:
Situation
When installed in a control panel
When installed near a heating
unit
When installed near a source of
vibration
When installed in a place
receiving corrosive gases
Others
Orientation:
Install the Servopack perpendicularly 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.
• Firmly secure the Servopack through three or
four mounting holes.
Notes on Installation
Design the control panel size, unit layout, and cooling
method so that the temperature around the periphery of
the Servopack does not exceed 55°C.
Suppress radiation heat from the heating unit and a
temperature rise caused by convection so that the
temperature around the periphery of 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 contactor-related devices to
malfunction. Take appropriate action to prevent corrosive
gases.
Avoid installation in a hot and humid place or where
excessive dust or iron powder is present in the air.
