Mounting Recommendations - Advantech ICR-4401 Hardware Manual

1. Product Overview

1.7 Mounting Recommendations

The router can be placed in the following ways:
• On a flat surface.
• On a wall using the wall mounting clip (refer to Chapter 1.8).
• On a DIN rail EN 60715 with the metal DIN rail clip (refer to Chapter 1.9).
For most applications involving a built-in router within a switchboard, two types of environments are
typically encountered:
• A non-public industrial environment with low voltage but high interference.
• A public environment with low voltage and without high interference.
For both of these environments, it's feasible to mount the router to a switchboard, eliminating the need
for immunity examination or EMC-related issues as per EN 61439-1:2011 standards.
To comply with the EN 61439-1:2011 specification, follow these assembly instructions when attaching
a router to a switchboard:
• When using whip antennas, maintain a minimum distance of 6 cm from cables and metal surfaces on
all sides to avoid interference. If an external antenna is used apart from the switchboard, a lightning
conductor is necessary.
• When mounting a router on sheet steel, consider using a cable antenna.
For all cables, it's recommended to bundle them, following these guidelines:
• The combined length of the cable bundle (power supply and data cables) should not exceed 1.5 m.
If data cable length surpasses 1.5 m or if the cable runs toward the switchboard, installing surge
protectors is advisable.
• Data cables must not be bundled with mains voltage cables (230 V/50 Hz or 120 V/60 Hz).
• Ensure sufficient space is left between each connector for cable handling.
• For proper router functionality, use an earth-bonding distribution frame to ground the grounding screw
(refer to Chapter 2.5).
