STEP 2 & 3:
Slightly pull the AWK-1151C forward and lift it up to remove it from the mounting rail

Wall Mounting (Optional)

For some applications, it may be more convenient to mount the AWK- 1151C to a wall, as illustrated below.

STEP 1:
Remove the aluminum DIN-rail attachment plate from the AWK-1151C, and then attach the wall-mounting plates with M3 screws, as shown in the adjacent diagrams.

STEP 2:
Mounting the AWK-1151C to a wall requires 2 screws. Use the AWK-1151C device, with wall-mounting plates attached, as a guide to mark the correct locations of the 2 screws on the wall. The heads of the screws should be less than 6.0 mm in diameter, the shafts should be less than 3.5 mm in diameter, and the screw length should be at least 15 mm, 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 plates before they are fixed to the wall.

STEP 3:
Once the screws are fixed into the wall, insert the screw heads through the large opening of the keyhole-shaped apertures, and then slide the AWK-1151C downwards, as indicated to the right. Tighten the screws for added stability .

Wiring Requirements

WARNING: Safety First!
Be sure to disconnect the power cord before installing and/or wiring your AWK- 1151C. Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes that dictate the maximum current allowed for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment. Be sure to disconnect the power cord before installing and/or wiring your AWK-1151C. Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes that dictate the maximum current allowed for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.

Read and Follow These Guidelines

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 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 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 separated.
• For future reference, you should label the wiring used for all of your devices.

NOTE The product is intended to be supplied by a UL Listed Power Unit marked “L.P.S.” (or “Limited Power Source”) and is rated 9-30 VDC, 1.57-0.47 A min, Tma min. 75°C. If you need further assistance with purchasing the power source, please contact Moxa for further information.

NOTE If using a Class I adapter, the power cord must be connected to a socket-outlet with an earthing connection.

ATTENTION
Make sure the external power adapter (includes power cords and plug assemblies) provided with the unit is certified and suitable for use in your country or region.

Grounding the AWK-1151C
Grounding 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.

ATTENTION
This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel. The potential difference between any two grounding points must be zero. If the potential difference is NOT zero, the product could be permanently damaged.

Installations with Cable Extended Antennas for Outdoor Applications

If 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.
