Preface
1 Preface
The purpose of this User Manual is to familiarize users with the CMC 310 test set hardware and its
specifications.
This manual is supplemented by the Safe use of CMC test sets manual, on-site safety regulations and
existing national safety standards for accident prevention and environmental protection.
The CMC 310 test set requires a suitable control software or control device for operation.
► Consult the corresponding Getting Started manual or user documentation regarding the use of the
control software or control device.
Note:
• The Safe use of CMC test sets manual and the software manuals are supplied on CD/DVD together
with this User Manual.
• From time to time the manual is updated to reflect the actual development status or changes of the
test set’s functional range. See page 2 for this manual’s version number.
1.1 Web Interface
The CMC 310 test set is additionally equipped with a Web Interface. The Web Interface enables you to
view device-specific parameters, and – depending on the device type – even provides you with
configuration features.
For more detailed information, see the according Web Interface help.
► Launch the Web Interface of that particular device, then click its help command. The Web Interface
is launched from the OMICRON Device Link tool.
1.2 Open source license information
Parts of the CMC 310 test set software are under OMICRON license, other parts are under open source
software licenses. Both the open source license texts and the necessary source code are provided in
the OMICRON Open Source Download Area at www.omicronenergy.com/opensource.
Open this address in your Internet browser, click the Download Software button, and navigate to the
CMC Embedded Image directory.
► Look for the file containing your version in the file name (for example, Open Source CMC embedded
Image 2.59.zip for version 2.59).
In addition to some open source code packages, the archive contains an overview of all license
information of the CMC test set.
WARNING
Death or severe injury caused by dangerous voltage possible
►Operate the CMC 310 only after you have read and fully understood the Safe use of
CMC test sets manual.

2 Safety
2.1 Designated use
The CMC 310 is a test set controlled by the CMControl P software for the testing of protection relays,
energy meters, SCADA systems and devices.
► Do not use CMC test sets in any other way than described in this document or in working
environments that exceed the specifications given in section 4 "Technical data". Improper use may
result in damage to persons or property.
2.2 Safety symbols used
In this document, the following symbols indicate safety instructions for avoiding hazards.
2.3 Safety instructions
► Before operating a CMC test set, carefully read the following safety instructions.
► Only operate (or even turn on) the CMC test set after you have read this manual including section
4 "Technical data" on page 18, and fully understood the instructions. We also recommend to read all
other relevant documentation for your test set and control software.
For your safety
Only trained personnel may operate CMC test sets. Any maloperation can result in damage to property
or persons.
You can remotely activate CMC test set outputs if the CMC is turned on and connected to a suitable
control software or control device (via network, wireless or USB).
► Observe all necessary safety measures given below.
All 4 mm safety sockets on the front panel can carry signals at dangerous levels and can conduct
dangerous voltages.
WARNING
Death or severe injury can occur if the appropriate safety instructions are not
observed.
NOTICE
Equipment damage or loss of data possible.

Safety
Rules for use
► Before operation, visually check for damages and make sure that the device and its accessories are
in a technically sound condition.
►Use CMC test sets only in accordance with the safety regulations for the specific job site and
application.
► Follow the instructions provided in the documentation.
► Testing with CMC test sets shall only be carried out by authorized and qualified personnel. Before
starting to work, clearly establish the responsibilities of all personnel involved.
► Personnel operating CMC test sets must be familiar with all necessary personal safety equipment.
► Testing with CMC test sets must comply with all on-site procedures and methods for personal safety.
► Personnel receiving training, instruction, direction, or education on CMC test sets should remain
under the constant supervision of an experienced operator while working with the equipment.
► Keep this document available on site where the CMC test sets are used.
Safe operation procedures
► Ensure proper grounding of the device and of the equipment under test.
► Use a power supply with protective earth.
► The power cable must be rated for the nominal voltage and current specified in section 4.2 "Main
power supply" on page 19. We recommend to use the cable supplied with the test sets.
► Do not block the access to safety-relevant test set components like the power switch or the power
cable.
►Operate CMC test sets only under the environmental conditions specified in section
4.7 "Environmental conditions" on page 35. Especially avoid a condensing environment.
► Do not operate CMC test sets when explosive gas or vapors are present.
► When setting up CMC test sets, make sure that the ventilation holes on the rear of the device remain
unobstructed.
► The fuse (→ section 2.5 "Changing the power fuse" on page 8) is the only serviceable part in CMC
test sets. Do not open CMC test sets or carry out any modifications, extensions, or adaptations.
►If CMC test sets seem to be functioning improperly, please contact OMICRON Support.
► Falling adapters or cables are a hazard. Test leads wired to tall test objects must be secured
mechanically.
► Do not connect any of the front panel outputs of VOLTAGE OUTPUT or CURRENT OUTPUT to
protective earth. The N sockets, however, may be connected to protective earth.
► Do not connect high inductive loads to CMC test sets.
► Observe the wiring instructions and safety precautions given in the Safe use of CMC test sets
manual.

2.4 Cleaning
Cleaning procedure:
1. Switch off the power switch.
2. Unplug the power cable from the power outlet.
3. Clean the CMC test set with a cloth dampened with isopropanol alcohol.
2.5 Changing the power fuse
Proceed as follows to replace the power fuse on your CMC test set:
1. Unplug the power cable of the CMC test set from the power outlet.
2. Locate the fuse on the back of the CMC test set.
3. Replace the fuse by an identical fuse type: Schurter 0001.2515 (T12.5 AH 250 V).

3.1 Description
The CMC 310 is a test set controlled by the CMControl P software. This User Manual describes the
hardware of the CMC 310. The configuration and control of the CMC 310 is carried out by the
CMControl P software. For more detailed information, read the user documentation.
3.2 Front panel connections
WARNING
Death or severe injury caused by dangerous voltage possible
All outputs and inputs of CMC test sets that are not explicitly restricted to SELV can carry
lethal voltage. The insulation between input and output groups on the front panel is only a
functional insulation and not sufficient to prevent dangerous voltages from being bridged
between ports. In case of an internal failure input ports can also be a source of
dangerous voltages.
► Before working on test objects, connections or terminals connected to the CMC test
set, make sure that the power supply of the CMC test set is switched off and that all
parts in the working area are de-energized.
► Observe the correct wiring procedure.

3.2.1 VOLTAGE OUTPUT
The 3 voltage outputs have a common neutral (N) that can be connected to protective earth, if required.
→ Section 4.4.3 "Voltage outputs" on page 25.
The amplifier is galvanically separated from all other connectors of the CMC 310.
All voltage outputs are protected against open circuits, L-N short circuits, overload, and
overtemperature.
► Do not connect any of the outputs of VOLTAGE OUTPUT to protective earth.
NOTICE
Equipment damage possible
An external infeed could damage the CMC test set.
► Make sure that there is no infeed from an external source.
