1–16 489 GENERATOR MANAGEMENT RELAY – INSTRUCTION MANUAL
CHAPTER 1: GETTING STARTED
1.4 Installation
1.4.1 Placing the Relay in Service
The relay is defaulted to the Not Ready state when it leaves the factory. A minor self-test
warning message informs the user that the 489 Generator Management Relay has not yet
been programmed. If this warning is ignored, protection will be active using factory default
setpoints and the Relay In Service LED Indicator will be on.
1.4.2 Testing
Extensive commissioning tests are available in Chapter 7. Tables for recording required
settings are available in Microsoft Excel format from the GE Multilin website at http://
www.GEmultilin.com. The website also contains additional technical papers and FAQs
relevant to the 489 Generator Management Relay.
