Wiring
Wire in accordance with applicable requirements of the latest
editions of the local codes and standards and the local
authority having jurisdiction.
Note: When stripping wire ends, exposing more wire may
cause a ground fault; exposing less wire may result in a faulty
connection.
To wire the module:
1. Verify that all field wiring is free of opens, shorts, and
ground faults.
2. Strip 1/4 in. (about 6 mm) from the ends of all wires that
connect to the terminal block of the module.
3. Make all wiring connections as shown in Figure 2.
Notes
• Refer to the Signature loop controller installation sheet for
SLC wiring specifications for additional details.
• All wiring is power-limited and supervised.
• A test resistor is supplied with the SIGA-CT1 to prevent
trouble signals on unused circuits during installation.
When connecting field wires, remove the test resistors and
install a UL/ULC Listed 47 KΩ EOLR at the end of the
circuit.
