4.7 Cooling Requirements
N O T I C E
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 sucient airow ow rate. See 4.8 Airow Rates.
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. Dierent
back-channel cooling kits are available to redirect the airow based on individual needs.
