Cooling Fan Replacement

200 V and 400 V Class Inverters of 18.5 kW or Less
A cooling fan is attached to the bottom of the Inverter.
If the Inverter is installed using the mounting holes on the back of the Inverter, the cooling fan can be replaced
without removing the Inverter from the installation panel.
If the Inverter is mounted with the heatsink external to the enclosure, the cooling fan can only be replaced by
removing the Inverter from the enclosure.
