6.1. CONNECTIONS AND NECESSARY EQUIPMENT

Necessary equipment:

∙One current source

∙One DC voltage source

∙Precision timer for testing timed events

∙One AC/DC voltmeter/ammeter

Connect the relay as indicated in the external connections diagram, Figure 2.

For safety reasons, the external protection earth should be securely grounded.

Apply dc rated voltage to terminals A10-B10

6.2. VISUAL INSPECTION

Check that the relay has not suffered any kind of damage due to transport and handling.

Check that all the screws are tight and the terminal blocks have not been damaged in any way.

6.3. PANEL INSULATION TESTS

!

If any insulation test would be performed on the panel where the relay is installed, the ground terminals A9-B9 must remain ungrounded.

Do the following groups in the terminals of the relay:

Group 1: A10, B10

Group 2: A1 to A4, B1 to B4

Group 3: C9, C10, D9, D10, C11, C12, D11, and D12

Group 4: A11, B11, A12, and B12

Group 5: C1, D1, C2, D2, C3, and D3

Group 6: C4, C5, C6, C7, C8, D4, D5, D6, D7, and D8

If the relay has expansion board, then the following groups must be added:

Group 7: E7, F7, E8, F8, E9, F9, E10, F10, E11, F11, E12, and F12

Group 8: E1, F1, E2, F2, E3, F3, E4, F4, E5, F5, E6, and F6

Apply 2000V gradually between case and groups.

Apply 2000V gradually between groups.
