SAFETY INSTRUCTIONS
This section contains the basic safety symbols that may
appear on the accompanying User Manual CD or on the
instrument. For detailed safety instructions and
precautions, please see the Safety Instructions chapter
in the user manual CD.
Safety Symbols
These safety symbols may appear in the user manual or
on the instrument.
Warning
Warning: Identifies conditions or
practices that could result in injury or
loss of life.
Caution
Caution: Identifies conditions or
practices that could result in damage
to the instrument or to other
properties.
DANGER High Voltage
Attention Refer to the Manual
Protective Conductor Terminal

Do not dispose electronic equipment
as unsorted municipal waste. Please
use a separate collection facility or
contact the supplier from which this
instrument was purchased.

Power Cord for the United Kingdom
When using the instrument in the United Kingdom,
make sure the power cord meets the following safety
instructions.
NOTE: This lead/appliance must only be wired by
competent persons.
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in
accordance with the following code:
Green/ Yellow:
Earth
Blue:
Neutral
Brown:
Live (Phase)
As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed as
follows:
The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol
or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal
marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or
contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable of
0.75mm2should be protected by a 3A or 5A fuse. Larger conductors
would normally require 13A types, depending on the connection
method used.
Any exposed wiring from a cable, plug or connection that is engaged
in a live socket is extremely hazardous. If a cable or plug is deemed
hazardous, turn off the mains power and remove the cable, any
fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.

GETTING STARTED
The Getting Started chapter introduces the instrument’s
main features, appearance, and set up procedure.
Overview
The PEL-3000 Series is a family of high performance DC
electronic loads positioned to test a wide range of
different power sources. The DC electronic loads are
fully programmable to simulate anything from basic
static loads to complex dynamic loads. With the ability
to operate independently or in parallel, the PEL-3000
Series is extremely robust and capable of molding to
any test environment.
