NOTE:
1. Due to a small protruding part of the heat sink at the bottom of the Frame A1/ A2, we calculate the distance C
for the side-by-side horizontal installation according to the main part of the motor drive only.
2. Frame A1 and A2 does not support zero-stack installation, whereas Frame B supports zero-stack installation.
3. Running the drive continuously with full load by the ambient temperature listed in the “Max. (derating)” column
reduces the drive’s life span.
4. Install the drive vertically to achieve the optimal heat dissipation performance.
5. The back surface of the drive for installation must be a metal material with higher temperature endurance and
good heat dissipation.
