6. Environment conditions:

- The BENNING CC 2 is intended for making measurements in dry environ-

ment.

- Maximum barometric elevation for making measurements: 2000 m,

- Overvoltage category IEC 60664/ IEC 61010, 600 V category III,

- Contamination degree 2 according to EN 61010-1

- Protection Class: IP 30 (DIN VDE 0470-1 IEC/ EN 60529)

IP 30 means: Protection against access to dangerous parts and protection

against solid impurities of a diameter > 2.5 mm, (3 - first index). No

protection against water, (0 - second index).

- Operating temperature and relative humidity:

For operating temperatures from 0 °C to 30 °C: relative humidity less than 80 %

For operating temperatures from 31 °C to 40 °C: relative humidity less than 75 %

For operating temperature from 41 °C to 50 °C: relative humidity less than 45 %

- Storage temperature: The BENNING CC 2 can be stored at any temperature

in the range from 20 °C to + 60 °C ).

7. Electrical specications

Note: The measuring precision is specied as the sum of

- a relative fraction of the measured value and

- a current value in A.

The measurement precision applies at a temperature of 23 °C ± 5 °C and a

relative humidity less than 75 %.

Further specications:

- sinusoidal alternating current (AC) with 48 Hz - 65 Hz

- harmonic distortion < 1%

- no DC component

- external magnetic eld: terrestrial magnetic eld (< 40 A/ m)

- no other live conductors nearby

8. Making measurements with the BENNING CC 2

8.1 Preparations for making measurements

Operate and store the BENNING CC 2 only at the specied storage and

operating temperatures. Avoid continuous insulation.

- The nominal voltage and current ratings of the safety measuring

cables included in the scope of delivery correspond to the ratings of the

BENNING CC 2.

- The safety measuring cable is securely connected to the BENNING CC 2

and cannot be removed.

- Check the insulation of the safety measuring cables. Discard the

BENNING CC 2 immediately if the insulation is damaged.

- Do not clamp the measuring pliers on a live conductor before the

BENNING CC 2 has not been connected to a multimeter.

Strong sources of interference in the vicinity of the BENNING CC 2 can lead

to unstable readings and measuring errors.

- Do not apply any voltage to the output contacts of the BENNING CC 2.



Do not exceed the maximum permitted voltage with respect to

earth potential! Electrical danger!

The highest voltage, that may be applied to the BENNING CC 2 against ground

potential, is 600 V.
