Precautionary Notes on External Heatsink (IP00/Open-Type Enclosure)
When using an external heatsink, UL compliance requires covering exposed capacitors in the main circuit to prevent injury
to surrounding personnel.
The portion of the external heatsink that projects out can be protected with the enclosure or with the appropriate capacitor
cover after completing drive installation. Use Table D.7 to match drive models with available capacitor covers. Order capacitor
covers from a Yaskawa representative or directly from the Yaskawa sales department.
