UUT POWER SUPPLIES

The removal process for UUT Power Supplies and GPIB/HPIB Power Supplies

is almost identical. However for both types of supplies, extreme caution

should be exercised due to the considerable weight of the supplies.

Lower Rack Power Supplies

(Kikusui or Kenwood PD-35-20, Kikusui PD55-

10, and Kenwood PD56-10)

1) Remove the left side panel (side opposite the computer) to gain access to

the rear of the power supplies.

2) Disconnect the AC power cords from the AC/DC Distribution Box, and

remove the Power Output/Programming cables from the UUT Controllers.

3) Remove the screws in the front panel holding the lower rack in place, and

slide the entire rack forward out of the cabinet. The rack assembly is very

heavy so proceed with caution.

4) Remove the faulty supply from the rack and return for repair.

Upper Power Supplies

(PDA110-1.5L)

Repeat the above procedure except that the supply can just be removed by

removing the small upper and lower retaining brackets. No rack assembly

needs to be removed.

WARNING! Remove main power from tester before proceeding.
