Wiring The Power Inputs; Wiring The P-Fail Alarm Contacts - Advantech EKI-6558TI User Manual

2.6 Wiring the Power Inputs

Connect the positive and negative wires to PWR1 (V1+, V1-) and PWR2 (V2+, V2-) as
the power pin assignments shown below.

2.7 Wiring the P-Fail Alarm Contacts

The P-Fail alarm relay is provided to signal critical error conditions that may occur on
the switch. The contacts are energized upon powering up of the switch and remain
energized until a critical error occurs including power failure or Ethernet port
disconnection. Take the wiring illustration below as an example that illustrates the
proper relay connection forming a normally close circuit, and the connection is to be
broken when an error occurs.
