General Information

The TVB-2 is a go/no-go load box for verifying that the failure detectors of your

Associated Research electrical safety testing instrument are functioning properly.

Use the TVB-2 daily before you begin performing Hipot, Insulation Resistance,

Ground Bond and Ground Continuity tests. The TVB-2 is not intended to comply with any specific safety agency standard.

Note: the trip setting may vary up to 10% of the set value based on the combined tolerances of the instrument and the components used in the TVB-2.

Using the TVB-2

The TVB-2 load box consists of resistors of varying types that induce a PASS or

FAIL condition depending on the test parameters that are set in your electrical safety tester. The 8 banana jacks located on the top of the box can be used to apply the corresponding load to the output of your tester. Each banana jack should be used for a particular type of test, which is outlined on the layout of the load box.

To setup a test, connect the high voltage or high current test lead of your electrical safety tester to one of the GC, GB, ACW/DCW, or IR test points.

Connect the return lead to the Return point. Ensure that the settings on your electrical safety tester are less than or equal to the maximum recommended voltage, current and duty cycle settings of the TVB-2. When all connections have been made, press the TEST button to begin the test. With the correct settings entered into the electrical safety tester, connecting the output leads to a PASS

1936 terminal should result in a PASS. Connecting the output leads to a FAIL terminal should result in a FAIL.

Note: pay close attention to the maximum voltage and duty cycle limitations of each resistor. Applying voltages that are higher than the recommended maximum setting or duty cycles greater than indicated can cause damage to the TVB-2.

Note: attention à la tension maximale et les limites du cycle de travail de chaque résistance. L'application de tensions plus élevées que le réglage maximum recommandé ou cycles de travail supérieures à celles indiquées peut causer des dommages à la

DYSFONCTIONNEMENT DU PRODUIT

CAUTION: Never connect TVB-2 to any mains circuit directly

ATTENTION: Ne jamais connecter directement le TVB-2 à un circuit d'alimentation.

MAINTENANCE:

To prevent electric shock do not remove the instrument cover. There are no user serviceable parts inside. Routine maintenance or cleaning of internal parts is not necessary. Any external cleaning should be done with a clean dry or slightly damp cloth. Avoid the use of cleaning agents or chemicals to prevent damage plastic parts or lettering.

ENTRETIEN:

Pour éviter les chocs électriques ne pas enlever le couvercle de l'instrument. Il n'y a aucune pièce reparable par l'utilisateur. L'entretien de routine ou le nettoyage des pièces internes ne sont pas nécessaires. Tout nettoyage externe doit être fait avec un chiffon sec ou légèrement humide. Éviter l'utilisation de produits de nettoyage ou des produits chimiques pour éviter d’effacer les lettres ou d’abimer les pièces en plastique.

OPERATING ENVIRONMENT:

This instrument may be operated in environments with the following limits:

- Indoor Use Only

- Altitude: 2000 m

- Temperature: 0ºC to 40ºC

- Humidity: Maximum 80% RH at 31ºC decreasing to 50% RH at 40ºC
