Wiring Requirements
Wiring the Relay Contact (ALM)
The NPOEI-60W-1G and NPOEI-90W-1G have one set of relay
alarm outputs. This relay contact uses two contacts of the
terminal block on the top panel of the unit. The two contacts
of the 6-pin terminal block connector are used to detect
user-configured events. The two wires attached to the fault
contacts form an open circuit when a user-configured event
occurs. If a user-configured event does not occur, the fault circuit
will remain closed. Therefore, in the event of a power loss by
main power or aux power or system overload, an external signal
can be detected.
