Model 4288-10 Rear Support Rack-Mount Kit Assembly and Mounting Instructions

PA-953 Rev. E / July 2018
General guidelines
For most installations, the Model 3706A fills 2U of vertical rack space.
If you are using a screw terminal block accessory with auto cold junction compensation (CJC) thermocouple
measurements, such as the Model 3720-ST, be aware that this accessory has built-in temperature sensors.
The sensors monitor the temperature of the screw terminals when temperature measurements are being made
with thermocouples. To make sure the temperature measurements are accurate, these sensors must be in
stable ambient conditions (not subjected to hot spots).
Prepare the rack for Model 3706A installation
To prepare the rack for Model 3706A installation:
1. If possible, remove the cabinet sides from the rack.
2. Select a location in the rack to install the instrument.
3. To make it easier to install the instrument, clear as much space as possible around the selected
rack location.
4. Measure the distance from the front rail to the rear rail to determine where the support brackets will
need to be mounted on the instrument.
5. Install the eight retaining clips, four on the front rack rail and four on the rear rack rail. Slide each
retaining clip over a mounting hole so that the captive nut is on the inside of the rack cabinet.
