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 fan to prevent the internal temperature of the control box from exceeding the
environmental conditions.
(3) Others
Install the servo amplifier on a perpendicular wall in the correct vertical direction.

2.3 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 fan installed on the ceiling.
(3) When installing the control box in a place where there are much toxic gas, dirt and dust, 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.
