SEL-710 Card Options

The SEL-710 offers flexibility in tailoring I/O to your specific application. The SEL-710 has six rear-panel slots, labeled

as Slots A, B, C, D, E, and Z. Slots A, B, and Zare base unit slots, each associated with a specific function. Optional

digital/analog I/O cards are available for the SEL-710 in Slots C, D, and E. Optional communications cards are available

only for Slot C, an RTD card is available only for Slot D, ac voltage or ac voltages and differential current cards are

available only on Slot E, and current cards are available for Slot Z. The previous figure and table show the slot allocations

for the cards.

Because installations differ substantially, the SEL-710 offers a variety of card configurations that provide options for an

array of applications. Choose the combination of option cards most suited for your application.

Dangers, Warnings, and Cautions

Card Installation for Slots C, D, E, and Z

Perform the following procedure to install or replace any one of the cards into Slots C, D, E, or Zof the base unit:

1. Save the settings and event report data before installing the new card in the relay.

2. Remove the power supply voltage qfrom terminals A01+ and A02–, and then remove the ground wire

from the green ground screw.

3. Disconnect all the connection plugs.

4. Remove the eight screws on the rear iand remove the rear cover.

5. Remove the plastic filler plate covering the slot associated with the card being installed.

6. Insert the card in the correct slot.

Make sure the contact fingers on the printed circuit board are bent at an approximate 130-degree angle

relative to the board for proper electromagnetic interference protection.

7. Before reattaching the rear cover, check for and remove any foreign material that may remain inside the

SEL-710 case.

8. Carefully reattach the rear cover.

9. Reinstall the eight screws that secure the rear cover to the case i.
