2.3 Mounting The EKI-2525M/2526M supports two mounting methods: DIN-rail & Wall. 2.3.1 Wall mounting EKI-2525M/2526M can be wall-mounted by using the included mounting kit. Then, hang on the EKI-2525M/2526M to the nails on the wall. First, use the screws included in the package to combine the EKI-2525M/2526M and metal mounting kit.
2.3.2 DIN-rail Mounting You can also mount EKI-2525M/2526M on a standard DIN-rail by below steps. The DIN-rail kit is screwed on the industrial switch when out of factory. If the DIN-rail kit is not screwed on the industrial switch, please screw the DIN-rail kit on the switch first. First, hang the EKI-2525M/2526M to the DIN-rail with angle of inclination.

Then, let the device down straight to slide over the rail smoothly. See Figure 2.7 Figure 2.7: Installation to DIN-rail Step 2 Chapter2...
2.4 Network Connection The EKI-2525M or EKI-2526M has the SC type fiber port in multi mode (2Km). When you connect the fiber port to another one, please follow the below figure to connect it. Wrong connection will not allow the port to work normally. Figure 2.8: Pin Assignment of the Power Connector Attention This is a Class 1 Laser/LED product.
2.5 Power Connection The EKI-2525M/2526M supports dual +12 ~ 48 V power inputs and power-fail relay output. Figure 2.9: Pin Assignment of the 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).
