2.4 Installation
Follow the procedure below to install multiple servo amplifiers side by side in a control
panel.
2.4.1 Servo Amplifier Orientation
Install the servo amplifier perpendicular to the wall so the front panel containing connectors
faces outward.
2.4.2 Cooling
As shown in the figure above, allow sufficient space around each servo amplifier for cooling
by cooling fans or natural convection.
2.4.3 Side-by-side Installation
When installing servo amplifiers side by side as shown in the figure above, allow at least
0.39in. (10mm) between and at least 1.97in. (50mm) above and below each servo amplifier.
Install cooling fans above the servo amplifiers to avoid excessive temperature rise and to
maintain even temperature inside the control panel.
Environmental Conditions in the Control Panel
• Ambient Temperature:0 to 55°C
• Humidity:90% r.h., or less
• Vibration: 0.5 G (4.9 m/s
