series driver with any capacity can be mounted closely together.
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, operate the drivers at the ambient temperature of 0
to 45
or at 75% or less of the effective
load ratio.

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 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.
