◆ Precautionary Notes on External Heatsink (IP00/Open Type enclosure)
When using an external heatsink, UL compliance requires that exposed capacitors in the main circuit are covered to
prevent injury to surrounding personnel.
The portion of the external heatsink that projects out can either be protected with the enclosure, or with the appropriate
capacitor cover after regenerative unit installation is complete. Use the table below to match regenerative unit models and
capacitor cover. Capacitor covers can be ordered from a Yaskawa representative or directly from the Yaskawa sales
department. The table below lists available capacitor covers.
