Losses, cooling data and noise
IP22 cabinet with no extra fan
An IP22 cabinet should meet the following data to ensure efficient cooling of the
drive module. No extra fan is used. The pressure drop over the cabinet is the
additional counterpressure that the module fan is capable of overcoming while still
maintaining the required air flow through the module.
IP54 cabinet with an extra fan
An IP54 cabinet should meet the following data to ensure efficient cooling of the
drive module. An extra fan is used. The pressure drop over the cabinet is the
counterpressure the extra fan must overcome. The given fan types and filter
materials are examples. Corresponding products by another manufacturer may be
used as well. See the manufacturer’s Internet site for the detailed specification.
