simplified local configuration menu with added options, c) new fault recovery options, d) user-selectable remote
inhibit polarity, e) both standard (-1200) and LAN (-1.2K) models supported, f) original Operator Manual is replaced
by a CD that contains expanded KLP documentation, including a KLP Quick Start Manual, User Manual, Devel­oper’s Guide and Labview and IVI drivers.

2.2 DISASSEMBLY PROCEDURE

1. Disconnect all source power, load and programming cables from the power supply. If recently powered, allow
at least two minutes for the internal circuitry to discharge fully before removing the cover.

2. Note the serial number of the power supply on the nameplate located on bottom surface of the power supply
chassis.

3. Find a clean work surface with sufficient area to work on the power supply (an ESD-protected work surface is
ideal).

4. Place the wrist strap on your arm as indicated by the instructions for the wrist strap. Attach the clip to the power
supply's chassis. If the work surface is not ESD-protected, it is recommended that the chassis also be con­nected to a known good ground potential. Do not use source power protective earthing connections

unless known to be zero potential.

5. Remove fourteen (14) flathead screws from the power supply cover: five (5) on each side surface and four (4)
on the top surface. Remove the cover by lifting it straight up. It may be necessary to apply a slight outward
force at the lower edge toward the rear of the power supply to release the cover. Set the cover and screws to
the side.

2.3 CIRCUIT CARD ASSEMBLY (CCA) A4 PROM U7 REPLACEMENT (SEE FIGURE 1)

1. Locate PROM U7 on A4 CCA near the front of the power supply. Note the orientation of the label of the device
installed in the PLCC socket. (see Figure 1).

CAUTION: FAILURE TO USE THE ESD WRIST STRAP MAY DAMAGE THE PROM!

2. Touch the IC tube to the chassis of the KLP, then open one end of the tube.

3. Insert the hooked end of the supplied PLCC extraction tool into one of the two tooling notches located at oppo­site corners of the PLCC socket for U7. Applying firm, continuous pressure lift one corner of the PLCC free of
the socket, then lift the entire device free.

4. Examine the PLCC socket for damaged or bent contacts; if found, return unit to Kepco for repair.

5. Select the replacement device whose label bears the same serial number as that noted in PAR. 2.2, Step 2.
Orient the replacement device so that it is centered over the PLCC socket with the label oriented identically to
the original (see Step 1 above). Apply firm, even pressure to seat the new device fully within the socket.

6. Reinstall the cover by reversing the disassembly procedure (see PAR. 2.2, step 5).

7. Reinstall source power, load and programming cables and turn the unit on. Factory calibration is retained and
recalibration is not necessary.
