Mount the AWK-3131A on to a corrosion-free mounting rail that adheres to the EN 60715 standard.STEP 1: Insert the upper lip of the DIN-rail kit into the mounting rail. STEP 2:Press the AWK-3131A towards the mounting rail until it snaps intoplace.To remove the AWK-3131A from the DIN rail, do the following:STEP 1:Pull down the latch on theDIN-rail kit with a screwdriver.STEP 2 & 3:Slightly pull the AWK-3131Aforward and lift it up to remove itfrom the mounting rail.Wall Mounting (Optional)For some applications, it may be more convenient to mount theAWK-3131A to a wall, as illustrated below.STEP 1:Remove the aluminumDIN-rail attachment platefrom the AWK-3131A, andthen attach thewall-mounting plates withM3 screws, as shown in theadjacent diagrams.STEP 2:Mounting the AWK-3131A to a wall requires 3 screws.Use the AWK-3131A device, with wall-mounting platesattached, as a guide to mark the correct locations of the3 screws. The heads of the screws should be less than 6.0mm in diameter, and the shafts should be less than 3.5mm in diameter, as shown in the figure on the right.Do not drive the screws in all the way—leave a space of about 2 mm to allow room for sliding the wall-mounting panel between the wall and the screws.NOTE Test the screw head and shank size by inserting the screws into one of the keyhole shaped apertures of the wall-mounting platesbefore they are fixed to the wall.STEP 3:Once the screws are fixed into the wall,insert the four screw heads throughthe large opening of thekeyhole-shaped apertures, and thenslide the AWK-3131A downwards, asindicated to the right. Tighten thethree screws for added stability.WARNING• This equipment is intended to be used in a Restricted Access Location, such as a dedicated computer room where only authorized service personnel or users can gain access. Such personnel must be instructed about the fact that the metal chassis of the equipment is extremely hot and may cause burns. •Service personnel or users have to pay special attention and take special precautions before handling this equipment. •Only authorized, well-trained professionals should be allowed to access the restricted access location. Access should be controlled by the authority responsible for the location with lock and key or a security identity system. • External metal parts are hot!! Pay special attention or usespecial protection before handling the equipment.Wiring RequirementsRead and Follow These Guidelines:• Use separate paths to route wiring for power and devices. If powerwiring and device wiring paths must cross, make sure the wires are perpendicular at the crossing point.NOTE Do not run signal or communications wiring 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 todetermine 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 separated.•For future reference, you should label the wiring used for all of your devices.Grounding the AWK-3131AGrounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices.Installations with Cable Extended Antennas for Outdoor ApplicationsIf an AWK device or its antenna is installed in an outdoor location, proper lightning protection is required to prevent direct lightning strikes to the AWK device. In order to prevent the effects of coupling currents from nearby lightning strikes, a lightning arrester should be installed as part of your antenna system. Ground the device, antenna, as well as the arrester properly to provide maximum outdoor protection for the device.Arrester Accessories•SA-NMNF-01: Surge arrester, N-type (male) to N-type (female) •SA-NFNF-01: Surge arrester, N-type (female) to N-type (female) Wiring the Redundant Power InputsThe top two pairs of contacts of the 10-contact terminal block connector on the AWK-3131A’s top panel are used for the AWK-3131A’s two DC inputs. Top and front views of the terminal block connector are shown below.STEP 1: Insert the negative/positive DC wires Array into the V-/V+ terminals.STEP 2: To keep the DC wires from pulling loose,use a small flat-blade screwdriver to tighten thewire-clamp screws on the front of the terminalblock connector.STEP 3: Insert the plastic terminal blockconnector prongs into the terminal blockreceptor, which is located on the AWK-3131A’stop panel.NOTE Input Terminal Block (CN1) is suitable for wire size range of 12-28 AWG (3.31-0.0804 mm²) and a torque value of 4.5 lb-in(0.51 Nm).Wiring the Relay ContactThe AWK-3131A has one relay output, which consists of the two contacts of the terminal block on the AWK-3131A’s top panel. Refer to the previous section for detailed instructions on how to connect the wires to the terminal block connector, and how to attach the terminal block connector to the terminal block receptor. These relay contacts are used to indicate user-configured events. The two wires attached to the Relay contacts form an open circuit when a user-configured event is triggered. If a user-configured event does not occur, the Relay circuit will be closed.Wiring the Digital InputsThe AWK-3131A has two sets of digital inputs—DI1 and DI2. Each DI comprises two contacts of the 10-pin terminal block connector on the AWK-3131A’s top panel. Refer to the “Wiring the Redundant Power Inputs” section for detailed instructions on how to connect the wires to theterminal block connector, and how to attach the terminal block connector to the terminal block receptor.Cable Holder InstallationAttach the cable holder to the bottom of the AWK-3131A to keep cabling neat and avoid accidents that result from untidy cables.STEP 1: Screw the cable holder onto the bottomof the AWK-3131A.STEP 2: After mounting the AWK-3131A and plugging in the LAN cable, tighten the cable along the device and wall.Communication Connections 10/100BaseT(X) Ethernet Port ConnectionThe 10/100BaseT(X) ports located on the AWK-3131A’s front panel are used to connect to Ethernet-enabled devices.Below we show pinouts for both MDI (NIC-type) ports and MDI-X (HUB/switch-type) ports.
