2.4.1 Installing and Operating the 2099-10, 10MHz Reference
1.) Connect REFERENCE OUTPUTS, J1 and/or J2, to the external equipment (Figure 2.1).
2.) Connect 100- 240 (±10%) VAC, 47 - 63 Hz to AC connector on the back panel.
3.) Be sure DS6 (green, POWER) is on (Figure 2.2).
4.) Wait for DS4 (yellow, OVEN WARM-UP) to go off and/or contact closure at DB9 ALARM
connector, J19, to occur to insure that the oscillator oven is stabilized.
5.) AC Fuse - The fuse is a 5 mm X 20 mm, 2 amp slow blow (Type T) and is inserted in the far slot
in the drawer below the AC input as shown in Figure 2.3. There is a spare fuse in the near slot.
If a fuse continues to open, the power supply is most likely defective.
