Preface

PREFACE

The purpose of this reference manual is to familiarize users with the

CMC 356 test set and to show how to properly use it in various application

areas.

The manual contains important tips on how to use the CMC 356 safely,

properly, and efficiently. Its purpose is to help you avoid danger, repair

costs, and down time as well as to help maintain the reliability and life of the

CMC 356.

This manual is to be supplemented by existing national safety standards for

accident prevention and environmental protection.

The reference manual should always be available at the site where the

CMC 356 is used. It should be read by all personnel operating the test set.

Note: The OMICRON Test Universe software also installs a PDF version of

this reference manual. It can directly be opened by a mouse-click from the

help topic "User Manuals of OMICRON Test Universe".

In addition to the reference manual and the applicable safety regulations in

the country and at the site of operation, the usual technical procedures for

safe and competent work should be heeded.

Note: This reference manual describes the CMC 356 hardware - that is, the

physical test set. In order to get familiar with the software for controlling and

configuring the CMC 356, please refer to the software manuals and/or the

OMICRON Test Universe Help.

For Your Safety Please Note

The CMC 356 test set can output life-hazardous voltages and currents.

Throughout the manual, this symbol indicates special safety-relevant

notes/directions linked to the possibility of touching live voltages and/or

currents. Please thoroughly read and follow those directions to avoid life-

hazardous situations.

This symbol indicates potential hazards by electrical voltages/currents

caused by, for example, wrong connections, short-circuits, technically

inadequate or faulty equipment or by disregarding the safety notes of the

following sections.

CMC 356 Reference Manual

SAFETY INSTRUCTIONS

Before operating the CMC 356 test set, carefully read the following

safety instructions.

Only operate (or even turn on) the CMC 356 after you have read this

reference manual and fully understood the instructions herein.

The CMC 356 may only be operated by trained personnel. Any

maloperation can result in damage to property or persons.

Rules for Use

•TheCMC 356 should only be used when in a technically sound

condition. Its use should be in accordance with the safety regulations for

the specific job site and application. Always be aware of the dangers of

the high voltages and currents associated with this equipment. Pay

attention to the information provided in the reference manual and the

software documentation.

•TheCMC 356 is exclusively intended for the application areas specified

in section 1, "Designated Use" on page 11. The manufacturer/

distributors are not liable for damage resulting from unintended usage.

The user alone assumes all responsibility and risk.

• The instructions provided in this reference manual and the associated

software manuals are considered part of the rules governing proper

usage.

• Do not open the CMC 356 or remove any of its housing components.

Orderly Practices and Procedures

• The reference manual (or its "electronic PDF pendant", which is installed

to your computer with the OMICRON Test Universe software) should

always be available on site where the CMC 356 is used.

Note: The OMICRON Test Universe software also installs a PDF version

of this reference manual. It can directly be opened by a mouse-click from

the help topic "User Manuals of OMICRON Test Universe". The

Test Universe Help can be launched by clicking Help on the Start Page.

• Personnel assigned to using the CMC 356 must have read this reference

manual and fully understood the instructions herein.

• Do not carry out any modifications, extensions or adaptations at the

CMC 356.

Safety Instructions

Operator Qualifications

• Testing with the CMC 356 should only be carried out by authorized and

qualified personnel.

• Personnel receiving training, instruction, direction, or education on the

CMC 356 should remain under the constant supervision of an

experienced operator while working with the equipment.

Safe Operation Procedures

• Follow the instructions in sections 3.2 and 3.4 that describe the safe use

of the connecting cables and how to set the CMC 356 into operation.

•TheCMC 356 must only be used from a power outlet that has a

protective earth.

• Do not block the access to safety-relevant test set components like the

main power switch or the power cord. In cases of an emergency, these

components need free and quick access.

• Do not connect any of the front panel VOLTAGE/CURRENT OUTPUTS

1 ... 3 or VOLTAGE OUTPUT 4, respectively, to protective earth. The N

sockets, however, may be connected to protective earth.

• When connecting to the banana plug sockets, only use cables with

4 mm/0.16 " safety banana connectors and plastic housing. Always

insert plugs completely.

• Before connecting and disconnecting test objects, verify that all outputs

have been turned off. Never connect or disconnect a test object while the

outputs are active.

• When disconnecting power supply cables or test leads, always start from

the device feeding the power or signal.

• All sockets on the front panel are to be considered dangerous with

working voltages up to 300 Vrms. Only use cables that meet these

respective requirements to connect to the equipment.

• Red Signal Light :

If the voltage on any of the four voltage outputs or on the "AUX DC"

output exceeds 42 V, the associated signal light lights up.

• Do not insert objects (e.g., screwdrivers, etc.) into the sockets or into the

ventilation slots.

• Do not operate the CMC 356 under wet or moist conditions

(condensation).

CMC 356 Reference Manual

• Do not operate the CMC 356 when explosive gas or vapors are present.

• The SELV interface (SELV = Safety Extra Low Voltage) of the CMC 356 -

"Host Interf." or “ETH1”, "LL out" (Low Level Outputs), "ext. Interf." -

should only have external devices connected that meet the requirements

for SELV equipment according to EN 60950 or IEC 60950.

• For applications drawing DC current: The load may not exceed 3 mH

because of dangerous feedback current.

• When setting up the CMC 356, make sure that the air slots on the back,

top, and bottom of the test set remain unobstructed.

• Voltages up to 1 kV can be present inside the CMC 356! Therefore,

opening the CMC 356 is only permitted by qualified experts either at the

factory or at certified external repair centers.

•IftheCMC 356 is opened by the customer, all guarantees are

invalidated.

•CMC 356 Ethernet functionality (see section 5.2.1, "Ethernet Ports ETH1

and ETH2" on page 32):

- It is a product of laser class 1 (EN 60825, IEC 60825).

- Connect ETH1 only to Ethernet ports.

•IftheCMC 356 seems to be functioning improperly, please contact the

OMICRON Tecnical Support (see section "Contact Information /

Technical Support" on page 137).

Changing the Power Fuse

• Unplug the power cord between the test set and the power source.

• The fuse is located at the back of the test set.

• Fuse type: T12.5 AH 250 V (wire fuse 5 × 20 mm).

For safety reasons please use only fuse types recommended by the

manufacturer. Refer to 6.1, "Main Power Supply" on page 39 for more

information.
