Protective covers are attached to the top and bottom of the Drive. It is recommended to remove the protective covers before
operating a CIMR-P7U2030/4055 Drive and smaller in a panel to obtain the 113°F (45°C) ambient operating temperature.
Observe the following precautions when installing the Drive:
• in a clean location which is free from oil mist and dust.
• in an environment where metal shavings, oil, water, or other foreign materials will not get into the Drive enclosure.
in a location free from radioactive materials.

Controlling the Ambient Temperature

To enhance the reliability of operation, the Drive should be installed in an environment free from extreme temperature
variations. If the Drive is installed in an enclosure, use a cooling fan or air conditioner to maintain the internal air temperature
below 113° (45°C).

Protecting the Drive from Foreign Matter
During Drive installation and project construction it is possible to have foreign matter, such as metal shavings or wire
clippings, fall inside the Drive. To prevent foreign matter from falling into the Drive, place a temporary cover over the Drive.
Always remove the temporary cover from the Drive before Start-Up. Otherwise, ventilation will be reduced, causing the Drive
to overheat.
