Step 2: Mount the Drive –
Minimum Requirements This section describes the minimum requirements to mount the drive.
Minimum Mounting Clearances
Specified vertical clearance requirements are
intended to be from the drive to the closest
object that can restrict airflow through the drive
heat sink and chassis. The drive must be
mounted in a vertical orientation as shown, and
must make full contact with the mounting
surface. Do not use standoffs or spacers. In
addition, inlet air temperature must not exceed
the product specification.
Maximum Surrounding Air Temperature
Enclosure Rating Temperature Range
Open Type, IP 20, NEMA/UL Type 1 and flange mount 0…50 °C (32…122 °F)
IP54 and IP66 NEMA/UL Type 4X/12 0…40 °C (32…104 °F)
IMPORTANT Some drives are equipped with an adhesive label on the top of the chassis.
