4.2.2 Installation Site
The following precautions apply to the installation site
4.2.3 Orientation
Install the servo amplifier perpendicular to the wall as shown in the figure. The servo
amplifier must be oriented this way because it is designed to be cooled by natural convection
or by a cooling fan. Secure the servo amplifier using the mounting holes. The number of
holes varies (from two to four) with the frame size of the servo amplifier.
Situation
Installation Precaution
Installation in a Control Panel
Design the control panel size, unit layout, and cooling
method so the temperature around the servo amplifier
does not exceed 55°C (131
°
F)
.
Installation Near a Heating Unit
Minimize heat radiated from the heating unit as well as
any temperature rise caused by natural convection so
the temperature around the servo amplifier does not
exceed 55°C (131
°
F)
.
Installation Near a Source of
Vibration
Install a vibration isolator beneath the servo amplifier to
avoid subjecting it to vibration.
Installation at a Site Exposed to
Corrosive Gas
Corrosive gas does not have an immediate effect on the
servo amplifier, but will eventually cause electronic
components and contactor-related devices to
malfunction. Take appropriate action to avoid corrosive
gas.
Other Situations
Do not install the servo amplifier in hot and humid
locations or locations subject to excessive dust or iron
powder in the air.
