1.4 Mainframe installation

The operating temperature of IT8700 series electronic load is 0 to 40℃. A fan
cools the electronic load by drawing air through the top and sides and
exhausting it out by the rear side. The electronic load must be installed in a
location that allows sufficient space at the sides and back of the unit for
adequate air circulation. Minimum clearances for bench operation are 3cm on
the top. If there are radiator fan in your cabinet, please avoid installing the load
near the fan for cabinet fan because it will limit air circulation of load. If you are
installing equipment on top of your electronic load in the cabinet, use a filler
panel above the unit to ensure adequate for air circulation.
IT8702/IT8703/IT8702P/IT8703P has no accessory, each of them can be
installed directly on the 19-inch support through screw holes of the left ear.
