Safety
WARNING
Describes a potential hazard which could result in injury or death, or, a procedure
which, if not performed correctly, could result in injury or death.
!
CAUTION
Describes a procedure which, if not performed correctly, could result in damage
to data, equipment, or systems.
WARNING—High Energy and High Voltage
Exercise caution when using and calibrating a power supply. High energy levels
can be stored at the output voltage terminals on a power supply in normal
operation. In addition, potentially lethal voltages exist in the power circuit and on
the output and sense connectors of a power supply with a rated output greater
than 40 V. Filter capacitors store potentially dangerous energy for some time after
power is removed.
!
CAUTION
Operate the power supply in an environment free of flammable gases or fumes. To
ensure that the power supply’s safety features are not compromised, use the
power supply as specified in this manual and do not substitute parts or make any
unauthorized modifications. Contact the service technician for service and repair
help. Repairs must be made by experienced service technicians only.

Section 2. Installation and Configuration
Introduction
We usually install the APG interface in a power supply at the factory. Your local
distributor or service center can also install the interface, especially for use in a
previously-purchased supply already on site.
Initial Inspection
On first receiving your unit, perform a quick physical check.
•Ensure each package contains a power supply with its APG interface board
installed, and manuals for the power supply and the APG interface. Any
additional parts shipped with the power supply will be identified in the supply's
documentation.
•Inspect the unit for any signs of physical damage such as scratches, cracks, or
broken switches, connectors, or displays.
•Check the printed circuit board and components if you suspect internal damage.
If the unit is damaged, save all packing materials and notify the carrier immediately.
For additional information, please see the section titled, “Returning Power Supplies
to the Manufacturer” in the manual shipped with your complete unit.
!
CAUTION
If you remove the unit's cover, use proper static control techniques to avoid damage
to static-sensitive components on the printed circuit board.

Configuring
Configure and adjust the analog programming interface installed in your XT or HPD
DC power supply as indicated in this section. The front panel LEDs indicate when
V or I programming is selected (PGM), when TTL shutdown has occurred (S/D), and
when the supply exceeds the voltage trip point OVP). You can adjust the OVP right
at the front panel. You will find the main programming option switch and connector
on the unit's rear panel, see Figure 2.2.

Rear Panel J5 Connector
Make analog interface connections via the rear panel 25-pin female DSUB connector
designated J5. To provide the lowest noise performance, we recommend you use
shielded-twisted pair wiring for making connections from external circuits to the J5
connector. Use the shortest leads possible. Ground the shield to pin 6 (auxiliary
ground) on the J5 connector or to the chassis via one of the J5 connector screws.
Note:In order to maintain isolation of power supply output, any programming
source must also be an isolated source.
