DIN-Rail Mounting The aluminum DIN-rail attachment plate comes attached to the back panel of the AWK-1137C when you take it out of the box. If you need to reattach the DIN-rail attachment plate to the AWK-1137C, make sure the stiff metal spring is situated towards the top, as shown in the figures...
STEP 2: Mounting the AWK-1137C to a wall requires two screws. Use the AWK-1137C device, with wall-mounting plates attached, as a guide to mark the correct locations of the two screws. The heads of the screws should be less than 6.0 mm in diameter, and...
WARNING Safety First! Be sure to disconnect the power cord before installing and/or wiring your Moxa AWK-1137C. 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.

Grounding the Moxa AWK-1137C 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.
12-28 AWG (3.31-0.0804 mm²) and a torque value of 4.5 lb-in (0.51 Nm) ATTENTION If the AWK-1137C is connected to a motor or other similar type of equipment, be sure to use power isolation protection. Before connecting the AWK-1137C to the DC power inputs, make sure the DC power source voltage is stable.
Installing the Antenna-Locking Clamp Use the antenna-locking clamp to secure the antennas to the AWK-1137C for added stability when you install the device in a high-vibration environment. STEP 1: STEP 2: Slide the clamps into the antenna Use screws to fix the clamps to the port.
LED Indicators The front and side panel of the Moxa AWK-1137C contains several LED indicators. The function of each LED is described in the table below: Color State Description System start up complete and the system is in operation Blinking +...
