Yaskawa F7 Drive CIMR-F7U25P5

Warning: This inspection requires trained personnel with PPE!

Inspect conductors and wire connections for loose lugs, screws, wires, hot spots, corrosion, bent conductors, breakage, cracking, discoloration, and spacing

Inspect terminal blocks for looseness or damage

Check DC bus capacitors for leakage, ruptures, expansion, capacitance, and insulation resistance

Inspect relays and contactors for noise and contact discoloration

Check soft charge resistors for cracks and discoloration

Check control circuit operation, including speed reference voltage/current and I/O contact operation

Inspect the Cooling Fans/Fins & Heatsink for loose connectors

Check the digital operator for key functionality, and cleanliness

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

Warning: This procedure should be performed by a trained technician
