7.6.2. Minimizing 50/60 HZ Line Interference
Operating the BAI series amplifiers from an off-line source of 115 VAC or 230 VAC
creates some additional problems.
First, there is a potential problem of EMI generated from the switching power stage of the
BAI amplifier propagating through the bridge rectifier and out through the HI and LO
input AC line connections. Back-propagation of noise into the AC lines can be minimized
using a line filter. An example of such a filter and proper connection to the BAI amplifier
is shown in Figure 7-15.

Use 60 degree C copper conductors only
This configuration is especially important if the BAI amplifier operating at DC bus voltages of 160 VDC or 320 VDC (e.g., 115 VAC or 230 VAC input power).
