Chapter 2 Installation 2
2.1 LED Indicators The LED indicators located on the front panel display the power status and network status of EKI-2728I. Each of them has its own specific meaning as the tabke shown below. Table 2.
The EKI-2728I supports two mounting methods: DIN-rail & Wall. 2.3.1 Wall mounting Figure 2.2 Combining the Metal Mounting Kit 7 EKI-2728I User Manual Installation EKI-2728I can be wall-mounted by using the included mounting kit. Then, hang on the EKI-2728I to the nails on the wall. First, use the screws included in the package to combine the EKI-2728I and metal mounting kit. And then you can install the device firmly via the components, please see Figure 2.5 as below. Chapter 2 2.
2.3.2 DIN-rail Mounting You can also mount EKI-2728I on a standard DIN-rail by the steps as followsFirst, Note! The DIN-rail clip is screwed on the industrial switch when out of factory. If the DIN-rail clip is not screwed on the industrial switch, please screw the DIN-rail clip on the switch first. hang the EKI-2728I over the DIN-rail with angle of inclination. Figure 2.3 DIN-rail Installation Step 1 Then, let the device drop down straight to slide over the rail smoothly. Figure 2.
2.5 Power Connection The EKI-2728I supports dual +12 ~ 48 VDC power inputs and power-fail relay output. Figure 2.5 Power Connector You can connect an alarm indicator, buzzer or other signaling equipment through the relay output. The relay opens if power input 1 or 2 fails ( “Open” means if you connect relay output with an LED, the light would be off).
