We strongly recommend that you do not replace the lithium battery without the help of a Moxa support engineer. If you need to change the battery, contact the Moxa RMA service team. WARNING There is a risk of explosion if the battery is replaced with an incorrect battery type. Dispose of used batteries according to the manufacturer's instructions. Placement Options The UC-3400A computer can be mounted on to a DIN rail or on a wall. The DIN-rail mounting kit is attached by default. To order a wall-mounting kit, contact a Moxa sales representative. DIN-rail Mounting To mount the UC-3400A on to a DIN rail, do the following: 1. Pull down the slider of the DIN-rail bracket located at the back of the unit 2. Insert the top of the DIN rail into the slot just below the upper hook of the DIN-rail bracket. 3. Latch the unit firmly on to the DIN rail as shown in the illustrations below. 4. Once the computer is mounted properly, you will hear a click and the slider will rebound back into place automatically. UC-3400A Series Hardware User Manual 9 Wall Mounting (optional) The UC-3400A can also be wall mounted. The wall-mounting kit needs to be purchased separately. Refer to the datasheet for information on the wall-mounting kit to be purchased. For the mounting dimensions, refer to the figure below: To mount the computer on to a wall, do the following: 1. Attach two wall-mounting brackets with four M3 x 5 mm screws on the right side panel of the computer as indicated in the figure. 2. Use another four screws to fasten the computer on to a wall or a cabinet. Recommended Torque: 4.5±0.5kgf-cm UC-3400A Series Hardware User Manual 10 The additional four screws are not included in the wall-mounting kit and must be purchased separately. Refer to the following specifications for the additional screws to be purchased. Head Type: Pan/Doom Head Diameter: 5.2 mm < Outer Diameter (OD) < 7.0 mm Length: > 6 mm Thread Size: M3 x 0.5P 3. Push the computer to the left to ensure the computer is securely fixed to the mounting surface. UC-3400A Series Hardware User Manual 11 3. Hardware Connection Description This section describes how to connect the UC-3400A to a network and connect various devices to the UC3400A as well as how to power it. Wiring Requirements You must pay attention to the following common safety precautions before proceeding with the installation of any electronic device: · Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point. NOTE Do not run the wires for signal or communication and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately. · You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together. · Keep input wiring and output wiring separate. · We strongly advise that you label wiring to all devices in the system for easy identification. ATTENTION Safety First! Be sure to disconnect the power cord before installing and/or wiring the computer. Electrical Current Caution! Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment. Temperature Caution! Be careful when handling the unit. When the unit is plugged in, the internal components generate heat, and consequently the outer casing may be hot to touch by hand. UC-3400A Series Hardware User Manual 12 Connector Description Power Connector Connect the power jack to the terminal block located on the top panel, and then connect the power adapter to the power jack. Use a 12 to 24 AWG wire and secure the plug by screws with a minimum torque value 0.5 N-m (4.4253 lb-in). After the power is connected, it takes about 10 to 30 seconds for the system to boot up. Once the system is ready, the READY LED will light up. Attention The wiring for the input terminal block must be done by a skilled person. The wire type should be copper (Cu). ATTENTION The product is intended to be supplied by a UL Listed Power Unit marked "L.P.S." (or "Limited Power Source") and rated 9 to 48 VDC, 1.2 A (min.), Tma = 70°C. If you need further assistance with purchasing the power source, contact Moxa for further information. If you are using a Class I adapter, the power cord must be connected to a socket-outlet with an earthing connection. Grounding the UC-3400A Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). The grounding screw or GS (M4-type screw) is located on the top panel. When you connect to the GS wire, the noise is routed directly from the metal chassis to the ground point. NOTE The grounding wire must have a minimum diameter of 3.31 mm². UC-3400A Series Hardware User Manual 13 Ethernet Port The 10/100/1000 Mbps Ethernet port uses the RJ45 connector.
