1.2.3 Installing the Servo Amplifier
(1) Install the servo amplifier vertically to the ground so that the "ALPHA5"
characters (see the arrow in the figure on the right) on the front panel of the
servo amplifier is horizontal.
Use M4 screws with length between 12 and 20 mm for the mounting to the
control panel.
Use screws together with plane washers or spring lock washers or use
3-piece sems screw to avoid looseness.
When using plane washers, select the finished round type (large size with
φ 9 mm).
(2) Some parts of the servo amplifier generate heat during operation.
Cool the surroundings if the servo amplifier is installed inside the control panel.

(3) To install two or more servo amplifiers in the same control panel, the following shall be taken into
consideration.
Arrange the servo amplifiers transversely in principle in order to avoid thermal affection.
This servo amplifier is permitted to be installed side by side closely. However, when installing two
or more servo amplifiers with clearance of 5 mm or less between them, operate them at 60% load
factor or below with the ambient temperature 45°C or lower.
If clearance of 5 mm or over between adjacent servo amplifiers is provided, no limitation is
imposed on the operation frequency.
