Assembly

Internal insulator

Conductor: max. diameter 2.5 mm

Tighten with a hexagonal wrench.

WARNING

Strip the insulation covers of measurement cables so that when they are wired to the safety
terminal adapters, the conductive parts (bare wires) do not protrude from the adapters.
Also, make sure to fasten the safety terminal adapter screws securely so that measurement
cables do not come loose.

CAUTION

Use measurement cables with dielectric strengths and current capacities that are appropriate
for the voltage or current being measured.
Example: When making measurements on a current of 20 A, use copper wires that have a

conductive cross-sectional area of 4 mm

French

AVERTISSEMENT

Retirer les caches d’isolation des câbles de mesure de façon que les éléments conducteurs
(fils nus) ne dépassent pas des bornes lorsque les câbles sont branchés sur les bornes
d’entrée. Veiller également à serrer correctement les vis des bornes d’entrée de façon à
éviter la désolidarisation des câbles.

ATTENTION

Utiliser des câbles de mesure dont la rigidité diélectrique et la capacité de courant
conviennent pour la tension ou le courant à mesurer.
Exemple : Lors de la réalisation de mesures sur un courant de 20 A, utiliser des fils en cuivre

à section transversale conductrice de 4 mm2.

or greater.

1.

Remove approximately 15 mm of the covering from the end of the measurement cable and pass
the cable through the internal insulator.

2.

Insert the tip of the measurement cable into the plug. Fasten the measurement cable in place
using the supplied hexagonal wrench.

3.

Insert the plug into the internal insulator.

4.

Attach the external cover. Make sure that the cover does not come off.

Note

• Once you attach the cover, it is difficult to disassemble the safety terminal adapter. Use care
when attaching the cover.

• The measurement cable is not included. Please use your own.

Below is an illustration of the adapter after it has been assembled.

Note

Keep measurement cables as short as possible to minimize the loss between the circuit under
measurement and the instrument.
