Mounting Instructions
DIN-rail Mounting
The aluminum DIN-rail attachment plate is already attached to the product’s casing. To mount the device onto a DIN rail, make sure that the stiff metal spring is facing upwards and follow these steps.
- Pull down the bottom slider of the DIN-rail bracket located at the back of the unit
- Insert the top of the DIN rail into the slot just below the upper hook of the DIN rail bracket.
- Latch the unit firmly onto the DIN rail as shown in the illustrations below.
- Push the slider back into place.
Wall Mounting (optional)
The device can be mounted onto a wall using a wall-mounting kit. The optional wall-mounting kit should be purchased separately.
Follow these steps to mount the device onto a wall:
Step 1
Use four screws to fasten the wall-mounting brackets on the left panel of the device.
Step 2
Use another four screws to mount the device onto a wall or in a cabinet.
IMPORTANT!
The diameter of the screw heads should be greater than 7 mm and less than 14 mm; the diameter of the shafts should be less than 3 mm. The length of the screws should be greater than 6 mm.
NOTE
- Test the screw head and shank size by inserting the screws into one of the keyhole-shaped apertures of the wall-mounting plates before attaching the plate to the wall.
- Do not drive the screws in all the way—leave a space of about 2 mm to allow room for sliding the wall mount panel between the wall and the screws.
Wiring Requirements
- 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.
- 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.
- When necessary, it is strongly advised that you label wiring to all devices in the system.
NOTE
Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.
Grounding Requirements
There is a grounding connector located on the top panel of the device. Connect it to an appropriate grounded metal surface. Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI).
Connecting the Power Supply
Connect the power jack (in the package) to the DC terminal block (located on the top panel), and then connect the power adapter. It takes about 3 minutes for the system to boot up. Once the system is ready, the Power LED will light up. Both models support dual power inputs for redundancy.
ATTENTION
WIRING CAUTION
- Use wires with 12 to 26 AWG wire sizes to connect to V+, V-, and GND.
- The wire size of the power input and the earthing conductor should be the same.
- Remove 8 to 9 mm of the DC wires’ protective cover and use a torque of 4.5lb-in/0.51Nm to connect the wire.
- The max. wire temperature should not exceed 100°C.
- The terminal blocks do not accommodate more than one conductor wire per clamping point.
WARNING
- This product is intended to be supplied by a UL-listed power adapter or DC power source whose output meets SELV/LPS. The power source must be rated 12 to 48 VDC, minimum 1 A, and minimum TMA = 85°C.
- The power adapter should be connected to a socket outlet with an earthing connection.
If you need further information or assistance, contact a Moxa representative.
Wiring the I/Os
- There are four digital inputs and four digital outputs on the top panel. Refer to the figure on the left for detailed pin definitions.
- Use wires with 16 to 28 AWG wire sizes to connect to DI, DO, and GND.
- The exposed conductor wire length should be 7-8 mm and the max. wire temperature should not exceed 100°C. The terminal blocks do not accommodate more than one conductor wire per clamping point.
