Relays In Relay Module (1) Jumper block.The relays are located in the relay module on the rear of the GSC. The relays are permanently attached within the relay module and the relays are not removable. The entire relay module is replaced if a relay is faulty. See Testing and Adjusting, "Schematics and Wiring Diagrams (DC Schematics)"for more information.Some of the contacts of the relays are internally connected to the terminals of the relay module. The contacts are available for the customer to use. The voltage and current specifications for each terminal (relay) are listed in the following table. Note: Jumper block (1) is used to select the voltage range of the GSC voltmeter. Jumper block (1) is installed for systems that have 700 volt AC input. Jumper block (1) is NOT installed for systems with 150 volt AC input or for any unit that has external potential transformers. The relay module comes from the factory with jumper block (1). See Testing and Adjusting, "AC Voltage Range Selection".
