NFPA Class B SLC Using Isolator Modules
A variation of a Class B 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 can-
not accept two wires at one pin. Wire Class B SLC loops as shown in the figure below.
