Mechanical Installation
Environment & Cooling
The ACR7000 operates in an ambient temperature range of 0°C (32°F) to 50°C (120°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 cooling vents permit vertical air flow. Figure 2 on page 23
shows the mounting orientation, as well as the minimum top, bottom, and side installation clearances.
• Avoid installing heat-producing equipment directly below a drive.
• Ensure that 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 heat sink
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.
