Driver and PA backplane boards. On the IPA and PA backplane boards, drawing
numbers 801-0222-131 and 801-0222-101 respectively, the jumpers on TB1, TB2,
and TB3 are connected between terminals 2 and 3 for 208 to 240 VAC Delta or WYE
and connected between terminals 1 and 2 for 380 to 415 VAC Wye connections.
•
A neutral connection is required, from the AC service entrance to CB23 and CB24 (if
used) for the 380 to 415 volt WYE connection, but no neutral connection is required
for the 208 to 240 volt Delta or WYE connections. 440 to 480 VAC Delta or WYE
connections require a step down transformer
.
Figure 2-6 is a photo of the TB1 and the MOV board (on the left). These terminal
boards need to be properly jumpered depending on the AC mains voltage. Figure 2-7
and Figure 2-8 are sketches that show the various configurations of the MOV and
terminal block jumpers depending on AC mains and number of PA modules used in the
transmitter. The MOV’s and TB’s are accessed by removing a cover plate on the top of
the transmitter cabinet at the rear.
