The module is equipped with a fan unit that contains two cooling fans.
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or
death, or damage to the equipment can occur. If you are not a qualified

maintenance work.
WARNING!
Use the required personal protective equipment. Wear protective gloves and
long sleeves. Some parts have sharp edges.
Before you start replacing the fan kit of the converter module, make sure that the
connector at the end of the fan kit cable is compatible with the counterpart in the
module. Black connector is compatible only with the black counterpart, and gray
connector only with the gray counterpart. If the connectors are not compatible, replace
the connector at the end of the fan kit cable. Use the connector in the old fan kit, or
order a suitable connector from ABB.
