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.
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.

Safety Symbols
DANGER – High voltage.
Explanation: To avoid injury, death of personnel, or
damage to the instrument, the operator must refer to an
explanation in the instruction manual.
High temperature: This symbol indicates the temperature
is now higher than the acceptable range of human. Do not
touch it to avoid any personal injury.
Protective grounding terminal: To protect against
electrical shock in case of a fault. This symbol indicates
that the terminal must be connected to ground before
operation of equipment.
WARNING
The WARNING sign denotes a hazard. It calls attention to
a procedure, practice, or the like, which, if not correctly
performed or adhered to, could result in personal injury.
Do not proceed beyond a WARNING sign until the indicated
conditions are fully understood and met.
CAUTION
The CAUTION sign denotes a hazard. It may result in
personal injury or death if not noticed timely. It calls
attention to procedures, practices and conditions.
The Notice sign denotes important information in
procedures, applications or the areas that require special
attention. Be sure to read it carefully.

Precautions before Use
1. The Electronic Load is for indoor use only.
2. The altitude up to 2000 meters is allowed to use the Electronic Load.
3. All specifications are tested under 20°C ∼30°C except stated
otherwise.
4. The range of operating temperature is 0°C ∼40°C.
5. The range of storage temperature is -5°C ∼60°C.
6. The operating relative humidity is from 30% to 90%.
7. The storage relative humidity is from 10% to 95%.
8. The transient overvoltage at Mains supply is 250V.
9. To meet the safety requirements, load wires must be thick enough
not to overheat while carrying the short-circuit output current of the
device connected to the electronic load.
10. The load module can be damaged by electronic discharge (static
electricity). Use standard anti-static work practices when handling
and installing the modules. Avoid touching the connectors and the
circuit board.
11. Ensure the load always receives adequate ambient cooling air at all
times and air filters, ducks, etc are maintained regularly. If loads
are used with a cabinet, precautions should be taken to minimize
heating within the cabinet.
12. If the UUT may be damaged or an unsafe condition may occur in the
event of a load short circuit (e.g. certain types of batteries), or if there
is no means of de-energizing the UUT in the event of a load failure,
user may consider including a suitably rated circuit breaker, fuse or
other means of disconnecting the load from the UUT under
emergency conditions.
13. When using Model 63208, 63209, 63210 and 63211 the distance
should be 1 meter for chassis front and 2.5 meters for rear without
any foreign object blocking the vents or the hardware temperature
may rise and cause OTP.
14. The electronic load can operate with a 115/230 Vac input as
indicated on the left of the Electronic Load. The 100/200 Vac line
voltage input model is used in Japan only. If the factory set switch on
this label that does not correspond to the local nominal line voltage,
turn off the Mainframe power and disconnect the power cord.
15. When connecting the load cable to the load module, do not use a
load cable to connect a load module and short circuit other load
modules, or it may cause the load cable to burn out when loading
larger current.
16. This equipment is not intended for performing measurements on

xi
CAT I, II, III or IV.
* CAT IV – is for measurements performed at the source of the
low-voltage installation.
* CAT III – is for measurements performed in the building
installation.
* CAT II – is for measurements performed on circuits directly
connected to the low-voltage installation.
* CAT I – is for measurements performed on circuits directly
connected to mains.
