4.7 Cooling Requirements

OVERHEATING
Improper mounting can result in overheating and reduced performance.
-
Install the drive following the installation and cooling requirements.
Ensure that top and bottom clearance for air cooling is provided. Clearance requirement: 225 mm (9 in).
Provide sufficient airflow flow rate. See
Consider derating for temperatures starting between 45 °C (113 °F) and 50 °C (122 °F) and elevation 1000 m (3300 ft) above sea
level.
The enclosed drive, excluding the input power options cabinet, utilizes a back-channel cooling concept that removes the air used to
cool the heat sink. The heat sink cooling air carries approximately 90% of the heat out of the back channel of the drive. Different
back-channel cooling kits are available to redirect the airflow based on individual needs.
