■Installation of two or more servo amplifiers
• Close mounting is possible depending on the capacity of the servo amplifier. Refer to the following for
availability of close mounting. Page 30 Servo amplifier standard specifications
• When closely mounting multiple servo amplifiers, the servo amplifier on the right must have a larger depth
than that on the left. Otherwise, the CNP1, CNP2, and CNP3 connectors cannot be removed.
Leave a large clearance between the top of the servo amplifier and the cabinet walls, and install a cooling fan to prevent the
internal temperature of the cabinet from exceeding the environment.
When mounting the servo amplifiers closely, leave a clearance of 1 mm between the adjacent servo amplifiers in
consideration of mounting tolerances. In this case, keep the ambient temperature within 0  to 45  or use the servo
amplifier with 75% or less of the effective load ratio.
30 mm
or more
Leaving clearance
*1 For 11 kW to 22 kW servo amplifiers, the clearance between the bottom and ground will be 120 mm or more.
*2 When mounting MR-J4-500GF(-RJ), maintain a minimum clearance of 25 mm between the MR-J4-500GF(-RJ) and a servo amplifier
mounted on the left side.
Others
When using heat generating equipment such as the regenerative option, install them with full consideration of heat generation
so that the servo amplifier is not affected.
Install the servo amplifier on a perpendicular wall in the correct vertical direction.
