Important Safety Instructions

Before applying power to the system, verify that your product is configured properly for your
particular application.

WARNIN

WARNIN

Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.

Ensure that the AC power line ground is connected properly to the Power Rack input connector or
chassis. Similarly, other power ground lines including those to application and maintenance
equipment must be grounded properly for both personnel and equipment safety.

Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any
cable.

In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/user must
ensure that the output power lines are labeled properly as to the safety hazards and that any
inadvertent contact with hazardous voltages is eliminated.

Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety
glasses during open cover checks to avoid personal injury by any sudden component failure.

Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary
sales organizations can accept any responsibility for personnel, material or inconsequential injury,
loss or damage that results from improper use of the equipment and accessories.

Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above
(below) chassis ground.

The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.

Operating Manual for GPIB for XT/HPD Series Power Supply

Section 1. Features and Specifications

Description

The internal GPIB interface card allows you to operate your power supply from a
computer controller via the IEEE-488 communications bus. See Figure 1.1, “Sample
Configuration using GPIB Interface”.

The GPIB interface allows complete remote programming of your power supply,
including status reporting, settings query, and interrupt generation with
user-designated fault conditions. Both the voltage and current output are precisely
programmed directly in volts and amps with 16-bit resolution. Additionally, the
built-in DVM and current shunt measure the actual power supply output and provide
16-bit readback. The programming command set is easy-to-use and includes
software calibration commands. The interface card comes standard with several
protection features such as programmable over voltage protection, foldback, load
isolation signal, and soft limits.

14 Operating Manual for GPIB for XT/HPD Series Power Supply

Section 2. Installation and Configuration

!

Introduction

To use this product, you must have the following equipment:

• a compatible model of DC output power supply

• IEEE-488 connector and cable

• computer with an IEEE-488 interface card

• Computer-based communications software package

The GPIB interface is usually installed 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. The GPIB interface card will be
calibrated and configured with default settings. Y ou will need to configure the supply
for your system using the “Basic Setup Procedure” on page 18. Refer also to
Figure 2.1, pg. 16, Figure 2.2, pg. 16 and Figure 2.3, pg. 17 for drawings of the front
panel, the interface subplate, and the GPIB interface printed circuit board (PCB).

Initial Inspection

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.

On first receiving your unit, perform a quick physical check.

• Ensure each package contains a power supply with its GPIB interface board

installed, and manuals for the power supply and the GPIB 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.
