USER MANUAL G72 CHAUVIN ARNOUX

This device is compliant with safety standard IEC 61010-2-032 for voltages up to 300 V in category III. Failure to observe the safety instructions may result in electric shock, re, explosion, or destruction of the instrument and of the installations. The operator and/or the responsible authority must carefully read and clearly understand the various precautions to be taken in use. Sound knowledge and a keen awareness of electrical hazards are essential when using this instrument. If you use this instrument other than as specied, the protection it provides may be compromised, thereby endangering you. The safety of any system in which this device is incorporated is the responsibility of the system integrator. Comply with the environmental conditions of use. Do not use the instrument if its housing is open, deteriorated, or incorrectly reas- sembled. Before each use, check the integrity of the insulation of the core or of the arms of the clamps, of the housing, and of the lead. Any item of which the insulation is deteriorated (even partially) must be set aside for repair or scrapping. Before using your device, check that it is perfectly dry. If it is wet, it must be thoroughly dried before being connected or being operated in any way. When using the device, keep your ngers behind the physical guard. Do not subject the clamp to sprayed or falling water or other liquids. Keep the gap of the clamp absolutely clean. Any dirt, however little, may cause the device to malfunction. Use personal protection equipment systematically. Any repairs must be carried out by accredited skilled personnel. CONTENTS

1.1. CLAMPS G72 Detachable arm. Fixed arm. Special 4-point plug. Trigger. Shielded cord. Guard. Arrow identify- ing the direction of the current.13 Current clamps are used to measure the current owing in a cable without opening the circuit. They also insulate the user from dangerous voltages in the circuit. The G72 clamp can measure AC leakage currents up to 50A, at the usual industrial frequencies. It is based on the current transformer principle. Its ergonomic shape and small size make it ideal for measurements in electrical cabinets, distribution frames, and cable assemblies. 1.2. DELIVERY CONDITION The clamp is supplied in a cardboard box with : a Velcro fastener, a user manual in 5 languages, a verication certicate.

Connect the clamp to the current input of the tester. Press the trigger on the clamp to open the jaws. G72

Then clamp the cable that is to be measured. Where possible, the cable should be centred in the jaws of the clamp. The arrow on the housing should point in the expected direction of current ow. Release the trigger and make sure that the jaws have closed correctly. For details of the measurement conguration and technical characteristics, re- fer to the user manual of the tester with which you are using the current sensor.14

3.4. CONFORMITY TO INTERNATIONAL STANDARDS

Electrical safety according to IEC 61010-2-032. Maximum applicable voltage: 300 V Cat III. Type of current sensor as per IEC 61010-2-032: type A .

Except for the batteries, the instrument contains no parts that can be replaced by personnel who have not been specially trained and accredited. Any unauthorized repair or replacement of a part by an “equivalent” may gravely impair safety. 4.1. CLEANING Disconnect the clamp completely. Use a soft cloth, dampened with soapy water. Rinse with a damp cloth and dry rapidly with a dry cloth or forced air. Do not use alcohol, solvents, or hydrocarbons. Keep the air gaps of the clamps perfectly clean.
