To replace a Pioneer +5 Volt assembly with a Todd Multi-Output assembly, 
proceed as follows:

1. On the front panel of the main Signal Processor Frame Power Supply, 

turn off the main power switch. The indicator LEDs on the front panel 
will go out.

If there is a Redundant Signal Processor Frame Power Supply, also turn 
off its main power switch.

2. Inside the switcher Control Panel, turn off the main Control Panel 

Power Supply switch and (if present) the redundant Control Panel 
Power Supply switch.

3. At the rear of the equipment rack, disconnect AC power from the Signal 

Processor Frame Power Supply by unplugging the cable from the AC 
power source. If there is a redundant Signal Processor Frame Power 
Supply, also disconnect it from the AC power source.

4. Remove both the right and left rear covers of the power supply frame, 

as viewed from the rear, to access the wiring connections. See
