Wiring The Fault Alarm Contact; Mounting Installation - Planet ISW-504PT User Manual

2.1.5 Wiring the Fault Alarm Contact

The fault alarm contacts are in the middle of the terminal block
connector as the picture shows below. Inserting the wires, the Industrial
Fast Ethernet Switch will detect the fault status of the power failure,
or port link failure (available for managed model) and then forms an
open circuit. The following illustration shows an application example for
wiring the fault alarm contacts.
1. The wire gauge for the terminal block should be in the
range between 12 ~ 24 AWG.
2. Alarm relay circuit accepts up to 30V, max. 3A currents.
