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.

viii
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

installation, operation, and maintenance information carefully before using the product. Refer
to the documentation contained in this guide for complete product specifications.
If the product is used in a manner not specified, the protection provided by the product
warranty may be voided.
The types of product users are:
Responsible person is the individual or group responsible for the use and maintenance of
equipment, for ensuring that the equipment is operated within its specifications and operating
limits, and for ensuring that operators are adequately trained.
Operators use the product for its intended function. They must be trained in electrical safety
procedures and proper use of the instrument. They must be protected from electric shock and
contact with hazardous live circuits.
Maintenance personnel perform routine procedures on the product to keep it operating
property, for example, setting the line voltage or replacing consumable materials.
Maintenance procedures are described in the user documentation. The procedures explicitly
state if the operator may perform them. Otherwise, they should be performed only by service
personnel.
Service personnel are trained to work on live circuits, perform safe installations, and repair
products. Only properly trained service personnel may perform installation and service
procedures.
1.5 Safety Information
Please read through the following safety information before using the
product.
Measurement Category II is for measurements performed on circuits which are directly
connected to the low voltage installation.
To avoid possible electric shock or personal injury, please read and follow these guidelines
carefully:
Follow the guidelines in this manual and DO NOT use the power supply if the case is
damaged. Check the case and terminals. Then contact your distributor for the case
replacement.
When using the probes, always keep your fingers behind the finger guards.
Always connect the common test leads (black) before connecting the live test leads (red),
and disconnect the live test leads (red) before disconnecting the common test leads
(black). This will reduce the chance of an electric shock.
If you need to open the power supply’s case or replace any parts, read the instructions in
this manual first. You must be qualified to perform this action.
When replacing fuses, use only the same type and same rating as specified.
