Fault Notification Output
The PM8500 features a hardware fault notification circuit. This circuit drives a normally open or normally closed contact closure (1A, 30
VDC maximum). The fault output, using the orange-colored 3-pin terminal block (Phoenix Contact #1976010, supplied), is intended to
provide an external connection to a remote system monitor for fault notification purposes. Pin assignments are noted in Figure 10.
