3. Operating Instructions
The Model 3102D is factory set for positive output polarity. If negative polarity is re-
quired, change the internal polarity board before installing the unit in the NIM bin (re-
fer to the Internal Controls section, below, for instructions).
Installation
The Canberra Model 2000 NIM bin and Power Supply or equivalent power supply
conforming to DOE/ER-00457T will accommodate the Model 3102D. The right side
cover of the unit acts as a guide for insertion of the unit. Secure the module in place by
turning the two front panel captive screws clockwise until finger tight. It is recom-
mended that the NIM bin power switch be OFF whenever any module is installed or
removed.
The Model 3102D can be safely operated where the ambient air temperature is
between 0
°
C and +50
°
C. Perforations in the top and bottom of the unit’s frame
permit cooling air to circulate through the module. When rack mounted along with
other heat generating equipment, be sure to provide adequate clearance for a flow of
cooling air through the NIM bin.
Internal Controls
Remove the unit’s left side cover to change the internal controls. Figure 3 shows the
position of the internal controls.
WARNING The Model 3102D generates lethal high voltage, which will
be present for several minutes after the unit is switched
off.
Before removing the unit from the NIM bin, set the VOLTAGE control to 0.00 volts
and the HV ON/OFF switch to OFF.
Avoid the risk of injury. Leave the unit in the NIM bin until the voltage reduces to
0 volts, as indicated on the front panel digital display.
