SLC Circuits with Isolators NFPA Style 4 SLC Using Isolator Modules
A variation of a Style 4 operation using an ISO-6 isolator module to protect each branch of the SLC
is shown below. Each terminal on the ISO-6 acts as a single I300 module. Refer to Figure 4.2 for
ISO-6 wiring and to Section 4.1 for limitations. Note that the ISO-6 cannot accept two wires at one
pin. Wire Style 4 SLC loops as shown in the figure below.
