Yaskawa Yaskawa F7 Drive CIMR-F7U2015 CIMR-F7U2015

A cooling fan is attached to the bottom of the Drive.

If the Drive is installed using the mounting holes on the back of the Drive, the cooling fan can be replaced without removing the Drive from the installation panel.

If the Drive is mounted with the heatsink external to the enclosure, the cooling fan can only be replaced by removing the Drive from the enclosure.

Removing the Heatsink Cooling Fan

1. Turn off the input power before removing and installing the heatsink cooling fan.

2. Press in on the right and left sides of the fan cover in the direction of arrows "1" and then pull the fan out in the direction of arrow "2".

3. Pull out the cable connected to the fan from the fan cover and disconnect the power connector.

4. Open the fan cover on the left and right sides in the direction of arrows "3" and remove the fan cover from the fan.

Installing the Heatsink Cooling Fan

The terminal card can be removed and mounted without disconnecting the control wiring.

Important: Always confirm that input power is removed and the Charge LED is not lit before removing or mounting the terminal card.
