Power Supply Module Replacement
Removal and replacement of the power supply module is a simple matter of shutting off
the breaker on the front of the module, removing the 2 black screws in the front panel
and pulling the module out.
Before replacing the module with a new one be sure to check the AC voltage strapping
on the front side of the supply (inside the aluminum chassis). The power supply
modules can be strapped for 240 or 480 Vac but all Ranger supplies should be strapped
for 240 Vac operation. Proper strapping for 240Vac is shown in Figure 5-4, along with a
picture of the inside of the actual supply chassis. This information (and 480Vac
strapping) is also shown on the Power Supply Wiring Diagram, 843-5494-353 in the
schematic package.
