Physical Installation 1 - 11Checking and Controlling the Installation SiteInstall the Drive as described below and maintain optimum conditions. Installation SiteInstall the Drive to a non-combustible surface under the following conditions in UL Pollution Degree 2 environments. Thisexcludes wet locations where pollution may become conductive due to moisture, and locations containing conductive foreignmatter.Protective covers are attached to the top and bottom of the Drive. It is recommended to remove the protective covers beforeoperating a NEMA Type 1 Drive (Models CIMR-F7U2030/4055 and smaller) in a panel to obtain the 113° (45°C) ambientoperating 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 TemperatureTo enhance the reliability of operation, the Drive should be installed in an environment free from extreme temperaturevariation. If the Drive is installed in an enclosure, use a cooling fan or air conditioner to maintain the internal air temperaturebelow 113°F (45°C). Protecting the Drive from Foreign MatterDuring Drive installation and project construction, it is possible to have foreign matter such as metal shavings or wireclippings 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 Driveto overheat.Table 1.3 Installation Site SpecificationsType Ambient Operating Temperature Humidity Plenum RatedNEMA Type 1 14°F-to 104°F (-10-to +40°C) 95%-RH-or-less-(no-condensation) YesOpen Chassis 14°F-to 113°F (-10-to-+45°C) 95%-RH-or-less-(no-condensation) No
