Mounting guidelines

Do not mount the controller in a location with any of the environmental disturbances listed in

Mounting locations to avoid.

To mount the controller on DIN rail, complete the steps in Mounting the controller on a 35mm DIN

rail.

To mount the controller to an enclosure base plate, complete the steps in Mounting the controller

to an enclosure base plate.

Important: If you only use Wi-Fi connectivity for your FW Series controllers, a site survey

is mandatory. An undocumented site survey voids any return or warranty of FW products.

The wireless site survey determines the placement and number of required devices to

provide sufficient signal coverage to support a minimum data rate or throughput. A wireless

site survey also detects interference coming from other sources that could degrade the

performance of the wireless communication among devices. For more information on

obstacles that interfere with signal strength, refer to EasyIO FW Series Network Connectivity

Guide.

Mounting locations to avoid

Do not mount the controller in the following locations:

• In an area with excessive moisture, corrosive fumes, or explosion vapors

• Where excessive vibration or shock occurs

• In locations with excessive electrical noise, such as large magnetic interference, or variable

speed drive modules

Mounting the controller on a 35mm DIN rail

1. Mount a section of 35 mm or 1.38 in. DIN rail horizontally on the enclosure base plate.

Figure 4: 35 mm DIN rail

2. On the back of the controller, extend the mounting clips.

Figure 5: Extending the mounting clips

3. Hang the top mounting clip on the DIN rail and then place the controller on the DIN rail.

Figure 6: Placing the controller on the DIN rail

4. To secure the controller to the DIN rail, close the mounting clip.

Figure 7: Closing the mounting clips (rear view)

5. Optional: For added security, use DIN rail end clips. For more information, see DIN rail end

clips in Table 1.

Mounting the controller to an enclosure base plate

About this task:

If a DIN rail mount is not practical, the controller features two mounting holes to screw mount the

controller to an enclosure base plate.

1. Place the controller on the enclosure surface and mark the enclosure mounting holes on the

surface. For more information, see Enclosure mounting holes in Table 1.

2. Drill both holes in the enclosure base plate.

3. Screw the controller to the enclosure base plate.

Installing the antennas

1. Locate the two RP-SMA female jacks. For more information, see the following figure.

Figure 8: Locating the female antenna jacks

Table 2: Female antenna jack

Callout Description

1 RP-SMA female jacks

2. To connect the male antenna connectors to the a female RP-SMA jacks, screw on the

antennas in a clockwise direction.

Note: For a secure connection, when you tighten the antennas to the female RP-SMA

jack, hold the metal part of the RP-SMA male connector. A poor connection reduces

reception.
