8. When Isolator2 (4090-9122, 4098-9766, or 4098-9767) are present on the channel, the maximum number of units loads
between isolators is 50.
9. Fast recovery is only available if all isolators on the IDNet line are of the IDNet Isolator2 type. You can combine an Addressable,
such as 4090-9116, IDNet Isolator with an IDNet Isolator2 (4090-9122, 4098-9766, or 4098-9767), but it is not best practice.
10. The IDNet2 channel provides timely loop isolation in case of wiring fault. Depending on local codes, negligible disruption may be
achieved by using Isolator2 (4090-9122, 4098-9766, or 4098-9767) close-nippled to the FACU to provide faster fault isolation.
11. Isolator2 work to their full potential when installed on a system that follows 579-1324 IDNet Isolator2 Compatibility Chart.
