Physical Installation 1 - 13
Checking and Controlling the Installation Site
Install the Drive as described below and maintain optimum conditions.
Installation Site
Locate the E7 Drive as close as possible to the motor. Install the Drive under the following conditions in UL Pollution Degree
1 & 2 environments. This excludes wet locations where surfaces may become conductive due to moisture and contaminant
loading.
Protective covers are attached to the top and bottom of the Drive. It is recommended to remove the protective covers before
operating a CIMR-E7U2030/4055 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.
•
in a location free from harmful gasses and liquids.
•
in a location free from excessive vibration.
•
in a location free from chlorides.
•
in a location away from direct sunlight.
•
on a non-combustible surface.
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
°
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.
WARNING
The Drive heatsink temperature may exceed 158
°
F (70
°
C). Therefore, mount the Drive to a surface suitable
for high temperature.
