Situation Notes on Installation
When installed in a control panel
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.
When installed near a heating
unit
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.
When installed near a source of
vibration Install a vibration isolator underneath the Servopack to
prevent it from receiving vibration.
When installed in a place
receiving corrosive gases
Corrosive gases do not immediately affect the Servopack
but will eventually cause contactor-related devices to
malfunction. Take appropriate action to prevent corrosive
gases.
Others
Avoid installation in a hot and humid place or where
excessive dust or iron powder is present in the air.
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.
