EN • REV 04 • ISS 05AUG13

 

 

When connecting the network data riser, always wire 

the Network B (isolated) terminals on one SFS1-CPU 

module to the Network A (nonisolated) terminals on 

the next. See Figure

SLC wiring notes: 

 

SLC wiring is supervised. 

 

SLC2 (TB2) wiring is configured the same as SLC1 

(TB1). 

 

When connecting SLC wiring, if shielding is used it 

must be continuous, terminated at the shield terminal, 

taped throughout the entire circuit, and free from earth 

ground. 

 

SLC AUX power wiring is unsupervised. 

 

SLC AUX power on loops 1 and 2 is nonisolated and 

not used for loop smoke power. 

 

SLC AUX power on loop 2 (TB2) is available whether 

or not a second 3-SDC1 card is installed. 

 

SLC smoke power (SMK PWR) on loop 2 (TB2) is not 

available unless a second 3-SDC1 card is installed.
