Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your particular
application.
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 facilityAC input power is de-energized prior to connecting or disconnecting anycable.
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 normallygenerated 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 safetyglasses 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 subsidiarysales
organizations can accept any responsibility for personnel, material or inconsequential injury, loss or damage
that results from improper use of the equipment and accessories.
SAFETY SYMBOLS
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.

OVERVIEW
1.1 INTRODUCTION
This manual provides instructions for full remote programming control and
monitoring from a computer, for your SG series high power DC power supply.
For easy navigation to the applicable instructions, this manual separates
GPIB and RS232 setup instructions from Ethernet setup instructions. The
instructions then converge where they are common to all three interface
options. See Sections 1.2 and 1.3 for orientation. Use this programming
manual in conjunction with your SGA/SGe or SGI Operation manual.
1.2 IEEE 488.2 GPIB AND RS232 OPTIONS
If you are using the IEEE 488.2 GPIB or RS232 interface, go to:
Section 2 for features, functions and specifications,
Section 3 for configuration and remote programming setup
Section 6 for SCPI commands and definitions
Section 7 for calibration procedures
Section 8 for SCPI Status Implementation
1.3 ETHERNET OPTION
If you are using an Ethernet interface, go to:
Section 4 for features, functions, and specifications
Section 5 for configuration and for programming setup of your SG power
supply via the Ethernet
Section 6 for SCPI commands and definitions
Section 7 for calibration procedures
