Keep Out Foreign Materials - Mitsubishi Electric MELSERVO-JN Series Instruction Manual

2. INSTALLATION
(2) Installation of two or more servo amplifiers
Leave a large clearance between the top of the servo amplifier and the internal surface of the control box,
and install a cooling fan to prevent the internal temperature of the control box from exceeding the
environmental conditions.
When installing the servo amplifiers closely, leave a clearance of 1mm between the adjacent servo
amplifiers in consideration of mounting tolerances.
In this case, operate the servo amplifiers at the ambient temperature of 0
effective load ratio.

Leaving clearance
(3) 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 installing the unit in a control box, 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 control box or
a cooling fan installed on the ceiling.
(3) When installing the control box in a place where toxic gas, dirt and dust exist, conduct an air purge (force
clean air into the control box from outside to make the internal pressure higher than the external pressure)
to prevent such materials from entering the control box.
