DC power options, 52, 53, and 54, have isolated inputs, which permits operation from a
positive or negative power source. To reduce RFI/EMI emissions use a shielded power
cable. Connect the cable shield to the chassis ground pin labeled “G”.
NOTE:
Place the DC power switch in the OFF position prior to connecting DC power.

3.3.11 AC Power
The standard Master Oscillator receives primary power from a 90 to 264 VAC 50/60 Hz
power source. A detachable line cord is furnished in the ancillary kit. The supplied line
cord is compatible with AC receptacles (NEMA 5 - 15R) commonly found in the United
States and Canada. Alternate type line cords may be obtained locally. Connect the line
cord to the rear panel AC module and a properly grounded power receptacle.
The AC power module is equipped with a power switch, line voltage selector, EMI
filtering, and a fuse. Figure 3-17, AC Power Module, illustrates fuse replacement. The
AC fuse requires a 1.5 Amp, 250V Slo-Blo fuse. A spare is found in the ancillary kit.
NOTE:
The unit accepts the complete range of 90-264 VAC without a change in
instrument setup. Do not change the AC fuse value or line voltage selector.
The ‘115’ label must appear in the cover cutout.
