base of transformer line up with the anchor holes in the bottom of the transmitter.
10. Set the tap connections on control transformer T2, located on the right-hand wall of the
transmitter (as viewed from the back, see Figure 2.3). Based on your nominal line to line (or
line to neutral) voltage, select the tap position identified in Figure 2.6 that is closest to your
voltage. If necessary, disconnect wire # 141 and secure it to the selected tap.
11. Reinstall the back plate using the four mounting screws removed in Step 3.
