3.2 Installation Standards
The servo amplifier must be installed in a fully enclosed metal control panel. Observe the standards
for mounting servo amplifiers in control panels, including those for the mounting servo amplifiers side
by side in one control panel as shown in the following illustration.
• Servo Amplifier Mounting Orientation
Mount the servo amplifier vertically to the wall, with the front panel (the side with the panel operator
display) facing out.
• Cooling
Refer to the following diagram and leave sufficient space for cooling by fans and natural convection.
• Mounting Servo Amplifiers Side by Side in a Control Panel
Leave sufficient space on each side and at the top and the bottom of each servo amplifier. The
width on each side varies in accordance with the models of the servo amplifiers used.
Also install cooling fans above the servo amplifiers to disperse local pockets of warmer air around
the servo amplifiers.
• Inside the Control Panel
The conditions inside the control panel should be the same as the environmental conditions of
the servo amplifier. Refer to the environmental conditions in
2.1 General Specifications .
• During Operation
Do not touch the connectors or IO cables during operation if the panel door is open.
