with the relevant regulations, to perform work assigned while independently recognizing any hazards.

Warning

Danger of injury due to inadequate qualifications!

Improper handling may lead to serious damage to personnel and property. When in doubt, consult qualified

personnel.

Work which may only be performed by trained imc personnel may not be performed by the user. Any

exceptions are subject to prior consultation with the manufacturer and are conditional on having obtained

corresponding training.

Page 12

Chapter 2

Special hazards

This segment states what residual dangers have been identified by the hazard analysis. Observe the safety notes

listed here and the warnings appearing in subsequent chapters of this manual in order to reduce health risks and

to avoid dangerous situations. Existing ventilation slits on the sides of the device must be kept free to prevent

heat accumulation inside the device. Please operate the device only in the intended position of use if so

specified.

Danger

Lethal danger from electric current!

Contact with conducting parts is associated with immediate lethal danger.

Damage to the insulation or to individual components can be lethally dangerous.

Therefore:

In case of damage to the insulation, immediately cut off the power supply and have repair

performed.

Work on the electrical equipment must be performed exclusively by expert electricians.

During all work performed on the electrical equipment, it must be deactivated and tested for

static potential.

Injuries from hot surfaces!

Devices from imc are designed so that their surface temperatures do not exceed limits

stipulated in EN 61010-1 under normal conditions.

Therefore:

Surfaces whose temperature can exceed the limits under circumstances are denoted by the

symbol shown at left.

Industrial safety

We certify that the imc C-SERIES in all product configuration options corresponding to this documentation

conforms to the directives in the accident prevention regulations in "Electric Installations and Industrial

Equipment" (DGUV Regulation 3)*. This confirmation applies exclusively to devices of the imc C-SERIES, but not

to all other components included in the scope of delivery.

This certification has the sole purpose of releasing imc from the obligation to have the electrical equipment

tested prior to first use (§ 5 Sec. 1, 4 of DGUV Regulation3). This does not affect guarantee and liability

regulations of the civil code.

For repeat tests, a test voltage that is 1.5 times the specified working voltage should be used to test the isolation

for the highly isolated inputs (e.g. measurement inputs for high-voltage applications).

3 Assembly and connection

3.1 After unpacking...

Check the delivered system immediately upon receiving it for completeness and for possible transport damage.

In case of damage visible from outside, proceed as follows:

Do not accept the delivery or only accept it with reservations

Note the extent of the damage on the packing documents or on the delivery service's packing list.

Begin the claims process.

Please check the device for mechanical damage and/ or loose parts after unpacking it. The supplier must be

notified immediately of any transportation damage! Do not operate a damaged device!

Getting started with your imc measurement device (printed)

Note

File a claim about every fault as soon as it is detected. Claims for damages can only be honored within the

stated claims period.

3.2 Before commissioning

Condensation may form on the circuit boards when the device is moved from a cold environment to a warm

one. In these situations, always wait until the device warms up to room temperature and is completely dry

before turning it on. The acclimatization period should take about 2 hours. This is especially recommended for

devices without ET (extended environmental temperature range).

We recommend a warm-up phase of at least 30 min prior to measure.

Ambient temperature

The limits of the ambient temperature cannot be strictly specified because they depend on many factors of the

specific application and environment, such as air flow/convection, heat radiation balance in the environment,

contamination of the housing / contact with media, mounting structure, system configuration, connected cables,

operating mode, etc. This is taken into account by specifying the operating temperature instead. Furthermore, it

is not possible to predict any sharp limits for electronic components. Basically, reliability decreases when

operating under extreme conditions (forced ageing). The operating temperature data represent the extreme

limits at which the function of all components can still be guaranteed.

Notes on connecting Chapter 3

3.3 Notes on connecting

3.3.1 Precautions for operation

Certain ground rules for operating the system, aside from reasonable safety measures, must be observed to

prevent danger to the user, third parties, the device itself and the measurement object. These are the use of the

system in conformity to its design, and the refraining from altering the system, since possible later users may not

be properly informed and may ill-advisedly rely on the precision and safety promised by the manufacturer.

Note

If you determine that the device cannot be operated in a non-dangerous manner, then the device is to be

immediately taken out of operation and protected from unintentional use. Taking this action is justified under

any of the following conditions:

I. the device is visibly damaged,

II. loose parts can be heard within the device,

III. the device does not work

IV. the device has been stored for a long period of time under unfavorable conditions (e.g. outdoors or in

high-humidity environments).

1. Observe the data in the chapter "Technical Specifications", to prevent damage to the unit through

inappropriate signal connection.

2. Note when designing your experiments that all input and output leads must be provided with shielding

which is connected to the protection ground ("CHASSIS") at one end in order to ensure high resistance to

interference and noisy transmission.

3. Unused, open channels (having no defined signal) should not be configured with sensitive input ranges

since otherwise the measurement data could be affected. Configure unused channels with a broad input

range or short them out. The same applies to channels not configured as active.

4. If you are using a removable storage media, observe the notes in the imc software manual.

Particular care should be taken to comply with the storage device's max. ambient temperature limitation.

5. Avoid prolonged exposure of the device to sunlight.

Notes on connecting Chapter 3

3.3.2 Power supply

Each device is powered by a DC-supply voltage which is supplied via a 2-pin LEMO-plug.

Type designation LEMO plug:

Device

LEMO plug type designation

Size

FGG.1B.302 CLAD 52ZN

middle

FGG.0B.302 CLAD 52ZN

small

The permissible supply voltage range is 10 ... 32 V DC. The product package includes a corresponding desktop

supply unit (15 V DC) as an AC-adapter for mains voltage (110 .. 240 V 50/60Hz). The DC-supply inputs of our imc

measurement devices are not designed for a connection to a DC-grid.

Please note, that the operation temperature of the desktop supply is prepared for 0°C to 40°C, even if your

measurement devices is designed for extended temperature range!

The package also includes a cable with a ready-made LEMO-plug which can be connected to a DC-voltage source

such as a car battery. When using this, note the following:

Grounding of the device must be ensured. If the power supply unit comes with a grounding line, it would be

possible to ground the system "by force", by making a connection from this line to the plug enclosure (and

thus to the device ground). The table-top power supply unit is made to allow this. This manner of

proceeding may not be desirable because it may be desirable to avoid transient currents along this line

(e.g. in vehicles). In this case the ground-connection must be made to the device directly. For this purpose a

(black) banana jack ("CHASSIS") is provided.

The feed line must have low resistance, the cable must have an adequate cross-section. Any interference-

suppressing filters which may be inserted into the line must not have any series inductor greater than 1mH.

Otherwise an additional parallel-capacitor is needed.

Pin configuration:

The +pin is marked with a red dot.

Page 17

Notes on connecting Chapter 3

3.3.3 Grounding, shielding

In order to comply with Part 15 of the FCC-regulations applicable to devices of Class B, the system must be

grounded.

3.3.3.1 Devices with non-isolated power supply

CS devices

The DC-supply input on the device itself (LEMO-socket) is not galvanically isolated from the

housing (CHASSIS): -SUPPLY input is galvanically connected to CHASSIS internally. That means the

device's internal power supply circuitry is not isolated from the system reference ground or the

frame ("CHASSIS").

3.3.3.2 Devices with isolated power supply

CL devices

The DC-supply input on the device itself (LEMO-socket, female) is galvanically isolated from the

housing (CHASSIS): -SUPPLY input is not connected to CHASSIS internally. That means the device's

internal power supply circuitry is isolated from the system reference ground/frame ("CHASSIS"). If

the device is powered by an isolated DC-voltage source (e.g. battery), use the device's black

grounding socket ("CHASSIS") or the LEMO supply cable's shielding to ground the device.

3.3.3.3 Grounding with the use of the included power adaptor

imc CL Devices

Use of the included table-top power adaptor is protected by the power plug's protection ground connection: at

the adaptor's LEMO terminal, both the (-) pole of the supply voltage as well as the shielding and the plugs are

connected with the power cable's protection ground.

Page 18

Notes on connecting Chapter 3

3.3.3.4 Grounding with power supplied by a car battery

imc CL Devices with isolated DC-supply (e.g. battery)

If the power supply (e.g. car battery) and the measurement device are at different voltage levels, then if they

were connected by the supply line, it would cause a ground loop. For such cases, the isolated internal device

power supply ensures separation of the two voltage levels. The ground reference for the measurement device

must then be established in a separate step.

For running on an isolated DC power supply source (e.g. battery), either the grounding socket terminal, a

grounding contact on the device ("CHASSIS"), or the CHASSIS contact on the imc signal plugs must be used.

Isolated power inputs avoids ground loops in distributed topologies

With stationary installations and the use of (already isolated) AC/DC adapters, any system ground differentials

between the device and the central or local power supplies may not be relevant. The big issue in such a case, in

contrast to mobile, in-vehicle applications, is from where to obtain a reliable ground voltage. Since it is

convenient to use the AC power supply's protection ground line as the ground voltage, the LEMO-terminated

AC/DC adapters for imc measurement devices are designed so that the protection ground line is connected all

the way through to the LEMO plug's housing, thus securing the device's voltage level to protection ground.

Additionally, in the AC/DC-adaptor's LEMO-terminal (not the device's LEMO-socket!), the reference ground of

the power adapter is connected with the housing's (CHASSIS) protection ground: Since the AC/DC power adapter

is already isolating, as is the power input, this supply voltage's reference would not initially be defined and can

be set arbitrarily. In particular for reasons of suppressing HF (high-frequency) interference signals stemming

from the AC/DC switching power adapter, direct grounding is normally advisable.

Page 19

Notes on connecting Chapter 3

3.3.3.5 Shielding

Also, all signal leads to the device must be shielded and the shielding grounded (electric contact between the

shielding and the plug housing "CHASSIS").

To avoid compensation currents, always connect the shielding to one side (potential) only.If the imc DSUB block

screw terminal plug is used, the shielding should be connected to the pull-relief clamp on the cable bushing. This

part of the conductor-coated plastic plug housing has electrical contact to the device's housing, just as Terminals

15 and 16 (labeled: "CHASSIS", to the left and right of the imc-plug cable bushing) do; but is preferable to the

"CHASSIS" terminals for optimum shielding.

3.3.4 Potential difference with synchronized devices

When using multiple devices connected via the SYNC socket for synchronization purposes, ensure that all

devices are at the same voltage level. Any potential differences among devices may have to be evened out using

an additional line having adequate cross section.

If the synchronized devices are at different voltage levels, they should be compensated by means of a lead

having the appropriate cross-section. If the SYNC plug at your device is equipped with a yellow ring it is already

isolated and it is protected against potential differences.

Note

The yellow ring on the SYNC socket indicates that the socket is shielded from voltage differences.

3.3.5 Fuses (polarity-inversion protection)

The device supply input is equipped with maintenance-free polarity-inversion protection. No fuses or surge

protection is provided here. Particularly upon activation of the device, high current peaks are to be expected.

When using the device with a DC-voltage supply and custom-designed supply cable, be sure to take this into

account by providing adequate cable cross-section.

Page 20

Notes on connecting Chapter 3

3.3.6 Main switch

The main switch of all CS-devices takes the form of a flip switch.

The main switch of the CL-devices takes the form of a rocker switch, which activates the device when it is tipped

for approx. 1second in the "ON" direction.

Activation

Devices with rocker switch will be activated by clicking for approx. 1sec the"ON"position. Devices with flip

switch will be activated by setting the main switch to the"I"position.

Successful "booting" of the device is confirmed by three short beeps.

CS-devices: Upon activation, all 6 status LEDs blink twice.

CL-devices: There are no LEDs in this device type. Instead the start procedure is seen on the display.

The device is activated

CS-devices indicate the activated state by the Power LED shining.

CL-devices indicate the activated state by the Display being on.

Deactivation

Devices with rocker switch will be deactivated by clicking for approx. 1sec the "OFF"position. Devices with

flip switch will be deactivated by setting the main switch to the "O"position.

If the device is running a measurement, it does not deactivate immediately. First, any associated files are

closed on the internal hard drive before the device switches off automatically. This process lasts for a

maximum of about 10sec. It is not necessary to hold the main switch down for this duration!

CS-devices: The deactivation procedure changes the color of the Power LED.

CL-devices: The deactivation procedure itself is not indicated. After 10s, the device is completely

deactivated and the display switches off.

3.3.7 Remote control of the CL main switch

Alternatively to the manual main switch on the device's front panel (only CL devices), it is possible to switch the

device on and off by means of an electrical remote control contact. The terminal designated "REMOTE" on the

device's rear panel makes this available: either brief or longer connection of the signals "SWITCH" and "ON"

activates the device, connecting "SWITCH" with "OFF" switches it off.
