Precautions For Use - Chauvin Arnoux MiniFlex MA110 Notice De Fonctionnement

The MA110 is protected against voltages up to 600 V with respect to earth in measurement category
IV, or 1000 V in category III. The MA130 is protected against voltages up to 600 V with respect to earth
in measurement category III. The protection assured by the current sensor can be compromised if it is
used in a way that is not recommended by the manufacturer.
„ Comply with the rated maximum voltage and current and the measurement category.
„ Never exceed the protection limits stated in the specifications.
„ Comply with the conditions of use, that is to say temperature, humidity, altitude, degree of pollution
and location of use.
„ Do not use the instrument if it is open, damaged, or incorrectly reassembled. Before each use, check
the integrity of the insulation on the coil, the leads, and the electronic unit.
„ The application or withdrawal of the sensor on uninsulated conductors at dangerous voltages requires
the use of suitable safety equipment.
„ If it is not possible to power down the installation, follow safe operating procedures and use suitable
means of protection.
„ All troubleshooting and metrological checks must be done by competent, accredited personnel.
