SEL-300 Series Relays Firmware Upgrade Instructions

Upgrade Procedure

I. Return the Relay to

Service

Step 1. Follow your company procedures for returning a relay to

service.

Step 2. Autoconfigure the SEL communications processor port if you

have an SEL communications processor connected to the relay.

This step reestablishes automatic data collection between the

SEL communications processor and the relay. Failure to

perform this step can result in automatic data collection failure

when cycling communications processor power.

The relay is now ready for your commissioning procedure.
