2. INSTALLATION
(b) Installation of two or more drivers
POINT
Close mounting is available for the driver of under 3.5kW for 200V class and
400W for 100V class.
Leave a large clearance between the top of the driver 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 drivers closely, leave a clearance of 1mm between the adjacent drivers in
consideration of mounting tolerances.
In this case, make circumference temperature into 0 to 45
, or use it at 75 or a smaller 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 driver is not affected.
Install the driver 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 driver.
(2) Prevent oil, water, metallic dust, etc. from entering the driver through openings in the control box or a
cooling 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.
