Checking and Controlling the Installation Site
Install the Drive in the installation site described below and maintain optimum conditions.
Installation Site
Install the Drive to a non-combustible surface under the following conditions in UL Pollution Degree 2 envi-
ronments. This excludes wet locations where pollution may become conductive due to moisture, and locations
containing conductive foreign matter
Protective covers are attached to the top and bottom of the Drive. It is recommended to remove the protective
covers before operating a NEMA Type 1 Drive (Models CIMR-G7U2015/4015 and smaller) in a panel to
obtain the 113° (45°C) ambient operating temperature.
Observe the following precautions when installing the Drive. Make sure to install:
• In a clean location which is free from oil mist and dust.
• In an environment where metal shavings, oil, water, or other foreign materials do not get into the Drive.
• In a location free from radioactive materials and combustible materials (e.g. wood).
• In a location free from harmful gases and liquids.
• In a location free from excessive vibration.
• In a location free from chlorides
• In a location away from direct sunlight.
Controlling the Ambient Temperature
To enhance the reliability of operation, the Drive should be installed in an environment free from extreme tem-
perature variation. If the Drive is installed in an enclosure, use a cooling fan or air conditioner to maintain the
internal air temperature below 113°
F (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.
