2. INSTALLATION
2 - 3
(b) Installation of two or more servo amplifiers
POINT
Close mounting is possible depending on the capacity of the servo amplifier.
Refer to section 1.3 for availability of close mounting.
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
˚ C to 45 ˚ C or use the servo amplifier with 75% or less of the effective load ratio.

Leaving clearance Mounting closely
Note 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-J4-500B(-RJ), maintain a minimum clearance of 25 mm between the MR-J4-500B(-RJ) and a servo
amplifier mounted on the left side.
(2) 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.
