Install the drive vertically for sufficient cooling airflow.
Note:
Contact Yaskawa or your nearest sales representative for details about the drive models that can be installed on its side and their operating conditions.
Figure 1. Installation Orientation
- Upright installation
- Horizontal installation
Single Unit Installation
Install the drive with the clearances specified in Figure 2 to guarantee sufficient space for wiring and airflow.
Figure 2. Drive Installation Space (Single Unit)
- At least 50 mm (2 in)
- At least 30 mm (1.2 in) on both sides
- At least 120 mm (4.7 in) above and below
- Airflow direction
Mounting Multiple Drives Side-by-Side
Drive models 2003xB to 2075xB and 4002xB to 4039xB can take advantage of side-by-side installation.
When installing other drive models, ensure that enough space for single unit installation is placed around each drive.
When you do side-by-side installation of drives, make sure that there is enough space for the installation of the drives with the clearances specified in Figure 3. Set L8-35 = 1 [Installation Method Selection = Side-by-Side Mounting].
Derate the output current to match the surrounding air temperature.
Figure 3. Drive Installation Space (Side-by-Side Mounting)
- At least 50 mm (2 in)
- At least 30 mm (1.2 in) on both sides
- At least 2 mm (0.08 in) between each drive
- At least 120 mm (4.7 in) above and below
Note:
-
If the dimensions of the drives are different when you do side-by-side installation, line up the tops of all the drives. This makes it easier to replace the cooling fan later.
-
Remove the top protective covers of all drives when you mount IP20/UL Type 1 drives side-by-side.
-
When you do an external heatsink installation, you cannot install drives side-by-side.
