1.6 Checking and Controlling the Installation Site
Install the iQpump drive as described below and maintain optimum conditions.
◆ Installation Site
Locate the iQpump drive as close as possible to the motor. Install the iQpump drive under the following conditions in UL Pollution
Degree 1 and 2 environments. This excludes wet locations where surfaces may become conductive due to moisture and contaminant
loading.
Table 1.5 Installation Site Specifications
Protective covers are attached to the top and bottom of the iQpump drive. It is recommended to remove the protective covers before
operating a CIMR-P7U2030 / 4055-107 iQpump drive and smaller in a panel to obtain the 113
°F (45 °C) ambient operating temperature.
Observe the following precautions when installing the iQpump 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 iQpump 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 iQpump drive should be installed in an environment free from extreme temperature variations.
If the iQpump 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 iQpump Drive from Foreign Matter
During iQpump drive installation and project construction it is possible to have foreign matter, such as metal shavings or wire clippings,
fall inside the iQpump drive. To prevent foreign matter from falling into the iQpump drive, place a temporary cover over the iQpump
drive.
Always remove the temporary cover from the iQpump drive before Start-Up. Otherwise, ventilation will be reduced, causing the iQpump
drive to overheat.
WARNING
The iQpump drive heatsink temperature may exceed 158 °F (70 °C). Therefore, mount the iQpump drive to a surface
suitable for high temperature.
