Mounting diagram from section 4.7

Relay connection diagrams from section 4.8.1

￿CT and VT connection diagrams from section 4.8.2 Pilot wire connection diagrams from section 4.8.3

The 7SA511 relay is completely tested and preprogrammed at the factory prior to shipment. No special calibration, or maintenance is required.

4.1 Receiving and Handling the Relay

The relay is packed to protect against mechanical shock. Carefully remove the relay from the package and visually check it for external damage. If the relay is physically damaged, return it to the manufacturer immediately, and include a short damage report. Figure 4-1 shows an exploded view of the 7SA511 relay’s components.

Note: There is also a plastic bag attached to the side of the module housing. This bag contains the backup battery for the relay (see section 4.3).

Keep the original packing material. Should you need to transport the relay again, use the original packaging to avoid damaging the relay.
