Derating Depending on Ambient Temperature

When you install drives in a place where ambient temperatures are higher than the rated conditions or install drives
side-by-side in the enclosure panel, set L8-12 [Ambient Temperature Setting] and L8-35 [Installation Method
Selection]. Derate the output current as specified in
