Scenario 5: Installing a Remote Unit on a DIN Rail
Context
- The DIN rail has been secured in position.
- The remote unit is placed near the DIN rail for convenient movement.
- In this scenario, only hybrid cables can be used for power supply, and dedicated hybrid optical-electrical optical modules are required. Hybrid cables need to be prepared and routed onsite. For details about how to prepare hybrid cables, see Assembling Second-Generation Hybrid Cable.
- If optical fibers need to be used, industrial optical modules are required.
Tools and Accessories
All figures are for illustration purposes only and may not accurately depict actual devices or modules.
- ESD wrist strap or ESD gloves
- Phillips screwdriver
- Flat-head screwdriver
- M3 screws (four)
- DIN mounting kit
- DIN rail (prepared by the customer)
Procedure
- Wear an ESD wrist strap. Ensure that one end of the ESD wrist strap is grounded and the other end is in close contact with your wrist.
- Use a Phillips screwdriver to secure the DIN mounting kit to the rear of the remote unit with four M3 screws.
Ensure that the arrow on the DIN mounting kit points upwards.
Figure 2-24 Securing the remote unit to the DIN mounting kit - Position the rear panel of the remote unit in front of the DIN rail, and attach the remote unit to the DIN rail by locking the spring-loaded latch bolt into place.Figure 2-25 Installing the remote unit on a DIN rail
- Insert an optical module into an optical port on the remote unit and connect an optical fiber or a hybrid cable to the optical module.Figure 2-26 Connecting a hybrid cableFigure 2-27 Connecting optical fibers
- Insert a Phoenix connector into the power input port on the remote unit, and tighten the screws clockwise using a flat-head screwdriver.
- Connect one end of a ground cable to the ground screw on the right of the remote unit, and connect the other end to the ground point or ground bar.
If multiple remote units are installed, ensure that the distance between every two remote units is at least 10 cm.
