Which are the Drives in Altivar 31 Standard Range that has in-built Fan Units.
All the Drives in the Altivar 31 Standard Range has in-built Fan Units, except ATV31H018M2, ATV31H037M2, ATV31H055M2 and ATV31H075M2 Drives do not have Fan Units as they are very small drives and ambient cooling is sufficient.
In-built Fan Units does not mean that the Ambient Temperature is not to be maintained. You have to ensure that the Ambient Temperature as per specification data sheet of the Standard Range of Altivar 31 Drives is followed.
