8.2.2 Installing SERVOPACKS
8
The SGD-jjjN SERVOPACK is a book-shaped compact servo controller. Install the SER-
VOPACK according to the following instructions, since faulty installation may cause malfunc-
tion.
J Installation Site
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 subject to
corrosive gases
Other locations
J Orientation
Install the SERVOPACK perpendicular to the wall as
shown in the figure.
The SERVOPACK must be orientated as shown in the fig-
ure because it is designed to be cooled by natural convec-
tion.
D Firmly secure the SERVOPACK through the mounting
holes provided.
J Installation Method

30 mm (1.18 in) or more 10 mm (0.39 in) or more
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.
