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.
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 lower of the effective load ratio.

(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 Keep out foreign materials
(1) When drilling 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.
(3) When installing the cabinet in a place where toxic gas, dirt, and dust exist, conduct an air purge (force
clean air into the cabinet from outside to make the internal pressure higher than the external pressure) to
prevent such materials from entering the cabinet.
