Safety Summary
The following general safety precautions must be observed during all phases of operation,
service, and repair of this instrument. Failure to comply with these precautions or specific
WARNINGS given elsewhere in this manual will violate safety standards of design,
manufacture, and intended use of the instrument. Chroma assumes no liability for the
customer’s failure to comply with these requirements.
BEFORE APPLYING POWER
Verify that the power is set to match the rated input of this power supply.
PROTECTIVE GROUNDING
Make sure to connect the protective grounding to prevent an electric
shock before turning on the power.
NECESSITY OF PROTECTIVE GROUNDING
Never cut off the internal or external protective grounding wire, or
disconnect the wiring of protective grounding terminal. Doing so will
cause a potential shock hazard that may bring injury to a person.
FUSES
Only fuses with the required rated current, voltage, and specified type
(normal blow, time delay, etc.) should be used. Do not use repaired
fuses or short-circuited fuse holders. To do so could cause a shock or
fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or
fumes. The instrument should be used in an environment of good
ventilation.
DO NOT REMOVE THE COVER OF THE INSTRUMENT
Operating personnel must not remove the cover of the instrument.
Component replacement and internal adjustment can be done only by
qualified service personnel.

ix
Safety Symbols
DANGER – High voltage.
Explanation: To avoid injury, death of personnel, or damage to the
instrument, the operator must refer to the
explanation in the instruction
manual.
High temperature: This symbol indicates the temperature is
hazardous to human beings. Do not touch it to avoid any personal
injury.
Protective grounding terminal: This symbol indicates that the
terminal must be connected to ground before operation of the
equipment to protect against electrical shock in case of a fault.
Functional grounding: To identify an earth (ground) terminal in
cases where the protective ground is not explicitly stated. This
symbol indicates the power connector does not provide grounding.
Frame or chassis: To identify a frame or chassis terminal.

1. General Information
1.1 Introduction
This manual contains specifications, installation, operation, and programming instructions of
63200 series high power electronic loads. All the machines are tested according to safety
standard EN61010-1: TYPE POLLUTION II and INSTALLTION CATEGORY II.
1.2 Description
The functions of the 63200 series loads are the same except the variations on input voltage,
load current, and power ratings. They can be operated independently in constant current
(CC) mode, constant resistance (CR) mode, constant voltage (CV) mode or constant power
(CP) mode.
Figure 1-1 Front Panel of the Electronic Load
There are three groups of keypads on the electronic load front panel shown in Figure 1-1.
They are System keypad, Function keypad and Entry keypad from left to right.
