Technical data117Losses, cooling data and noiseIP22 cabinet with no extra fanAn IP22 cabinet should meet the following data to ensure efficient cooling of thedrive module. No extra fan is used. The pressure drop over the cabinet is theadditional counterpressure that the module fan is capable of overcoming while stillmaintaining the required air flow through the module.IP54 cabinet with an extra fanAn IP54 cabinet should meet the following data to ensure efficient cooling of thedrive module. An extra fan is used. The pressure drop over the cabinet is thecounterpressure the extra fan must overcome. The given fan types and filtermaterials are examples.
