MIEN2204 Series Unmanaged Industrial Ethernet Switch
3. Hardware Installation
3.1. Installation Requirements
This industrial Ethernet switch is a single structure. Before installation, you
must first confirm that there is a suitable working environment, including power
requirements, sufficient space, whether it is close to other network equipment
to be connected, and whether other equipment is in place. Please confirm the
following installation requirements:
Power requirements: standard products use 24V power supply. For other
power supply methods, please refer to the product label, the power supply
mark on the shell and the relevant manual
Environmental requirements: temperature -40℃～+85℃, relative humidity
5～95% (no condensation)
Grounding resistance requirements: <5Ω
According to the contract configuration requirements, check whether the
optical cable is laid in place and whether the optical fiber connector is suitable
Avoid direct sunlight, keep away from heat sources or areas with strong
electromagnetic interference
Standard products are installed on DIN rails. Check if there are cables and
connectors required for installation
Attention
Be sure to disconnect the power cord before installing or connecting the
Ethernet switch. Calculate the maximum possible current in each power line
and common line, and observe all electrical information to know the maximum
current allowed by lines of different widths. If the current exceeds the maximum
rated current, the wire will overheat and cause serious damage to the
equipment.
At the same time, you must also pay attention to the following:
Separate the paths of power lines and equipment lines. If the two paths
must cross, make sure that these lines are perpendicular at the intersection. It
is not allowed to lay signal wires or communication wires and power wires in
the same pipe. To avoid interference, wires with different signal characteristics
should be separated. We can use the type of signal transmitted in a line to
determine which lines should be separated. The rule of thumb is that wires with
the same electrical characteristics can be bundled together. Separate the input
line and output line. It is strongly recommended to label all equipment lines in
the system when necessary.
The switch must be connected to the protective ground:
