UTILITY FAIL RELAY

A "dry-contact" signal is provided to annunciate when the Utility
supply fails.
Singe-phase
A 240 VAC coil relay is connected across the Utility supply termi-
nals. The supply to the relay is fused with a 5A fuse in each line.
The normally closed contacts of the relay are connected to the
terminal strip for easy connection by the customer.
Three-phase
A three-phase voltage monitoring relay is connected across the
utility supply terminals. The voltage monitor relay is adjustabe
to the specific nominal voltage and the percent of dropout on
undervoltage. The voltage monitor is provided with a tri-color LED
(Figure 2).
