22 Aries User Guide
Environment & Drive Cooling The Aries drive operates in an ambient temperature range of 0°C (32°F) to
45°C (113°F) ambient air temperature for all models except the AR-13xx.
The AR-13xx operates in an ambient temperature range of 0°C (32°F) to
40°C (104°F) ambient air temperature. The drive can tolerate atmospheric
pollution degree 2. Only dry, non-conductive pollution is acceptable.
Therefore, it is recommended that the drive be mounted in a suitable
enclosure.
For drive cooling, you must install the drive so that the heatsink fins are
vertical. Figure 8 on page 31 shows the mounting orientation, as well as the
minimum top, bottom, and side installation clearances.
The Aries AR-20xE and AR-30xE models (2 and 3 kWs) employ internal fans
for additional cooling capacity. The AR-20xE has one fan and the AR-30xE
has two. The fans are located at the bottom of the drives. They draw air in
from the bottom, force it up over the heatsink, and out the vents in the top of
the drive. Fan speed is temperature-dependent in order to minimize audible
noise and extend fan operating life.
Notes
• Avoid installing heat-producing equipment directly below a drive.
• Make sure the ambient air temperature entering the drive or rising
up to the drive is within acceptable ambient temperature limits.
Under normal use, the temperature of air leaving the drive and
heatsink may be 25°C (45°F) above ambient temperature.
• After installation, verify that the ambient air temperature directly
below the top-most drive does not exceed the maximum Ambient Air
Operating Temperature shown below. In addition, make sure that
nothing obstructs the circulating airflow.
