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 mounting the servo amplifiers closely, do not install the servo amplifier
whose depth is larger than that of the left side servo amplifier since CNP1,
CNP2, and CNP3 connectors cannot be disconnected.
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 you install the MR-J4-500B(-RJ) on the right side, the clearance between the left side and wall will be 25 mm or more.
(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.
2.2 Keeping out of foreign materials
(1) When drilling in the cabinet, prevent drill chips and wire fragments from entering the servo amplifier.
(2) Prevent oil, water, metallic dust, etc. from entering the servo amplifier through openings in the cabinet or
a cooling fan installed on the ceiling.
