HIRSCHMANN MICE series modular industrial communication equipment

Connect the optical fiber jumper and pay attention to the cleanliness of the optical fiber interface (to avoid dust affecting transmission);

Caution: Only use HIRSCHMANN original SFP modules, non original modules may cause compatibility issues or equipment failures.

3. Installation of MB20 expansion module

Loosen the upper and lower fixing screws on the right side of the MICE basic module (rotate 1-3 turns without completely disassembling);

Remove the side cover of the basic module;

Fix the basic module on the guide rail (if not installed);

Push the MB20 expansion module along the guide rail to fit snugly with the base module, ensuring complete interface docking between modules;

Re tighten the two fixing screws on the basic module to secure the MB20 module.

4. Debugging and Startup

Power supply connection: Connect the NEC Class 2 standard power supply voltage through the terminal block of the basic module, lock the terminal block to prevent loosening;

Status check: Observe the LED indicator light on the module - the green Power light on indicates normal power supply; The port LED (green/yellow) status reflects the connection and data transmission status of the port (specific meaning depends on device settings);

Functional testing: Verify device interconnectivity through Ping commands and industrial communication protocol testing (such as Modbus, Profinet). The PoE module needs to test whether the terminal power supply is normal.

（3） Dismantling process

Disconnect the signal line of the module (the optical fiber needs to be pulled out first to avoid breakage);

Loosen the module fixing screws (media module) or unlock the SFP module locking device (SFP module);

Smoothly unplug the module to avoid violent pulling (to prevent damage to the interface pins);

Install protective covers for idle slots to prevent dust from entering.

Safety regulations and precautions

（1） Electrical safety

Power supply limitation: All modules only support NEC Class 2 standard power supply voltage. PoE modules require 48V DC safe low voltage and are prohibited from accessing voltage beyond specifications;

Explosion proof requirements: When used in Class I, Division 2, Groups A/B/C/D explosive hazardous areas, it is necessary to ensure that the equipment has been labeled with the corresponding explosion-proof identification, and only plug and unplug modules in environments where the system is powered off or there is no concentration of flammable gases; Replacing modules may affect explosion-proof compatibility and require the use of original spare parts;

Grounding requirements: The shielding layer of Twisted Air cables should be electrically conductive with the front panel of the equipment, and avoid forming a grounding loop during wiring to prevent electromagnetic interference.

（2） Static Electricity Protection (ESD)

The module contains electrostatic sensitive components (such as chips and interface circuits), and operation must comply with the IEC/TR 61340-5-2 standard:

Operators need to wear anti-static wristbands or touch grounded metal objects to release static electricity;

When storing modules, they should be placed in anti-static packaging bags to avoid contact with materials that are prone to static electricity, such as synthetic fibers and plastics;

It is prohibited to touch the exposed metal parts of the module's pins, interface gold fingers, etc. with your hands.

（3） Electromagnetic Compatibility (EMC)

The equipment has a Class A electromagnetic radiation rating and may cause radio interference when used in residential areas. Users are responsible for eliminating the interference themselves;

Strictly follow the wiring specifications in the manual during installation, use shielded cables (such as STP network cables), and avoid parallel laying with power cables (minimum spacing ≥ 30cm);

The equipment must meet the following EMC anti-interference standards:

Electrostatic discharge (EN 61000-4-2): Contact discharge ± 6kV, air discharge ± 8kV;

Electromagnetic radiation (EN 61000-4-3): 80~3000MHz, 10V/m;

Surge (EN 61000-4-5): Power port ± 4kV, data port ± 2kV;

Fast transient pulse (EN 61000-4-4): power port ± 2kV, data port ± 4kV.

（4） Environmental safety

Temperature limit: Standard module working temperature is 0 ℃~+60 ℃, expansion type (T/E grade) working temperature is -40 ℃~+70 ℃, storage temperature is -40 ℃~+85 ℃ (E grade with Confocal Coating anti condensation coating);

Humidity and air pressure: working humidity of 10%~95% (no condensation), maximum altitude of 2000m (795hPa), if exceeding the altitude, please consult the manufacturer in advance;

Pollution level: The environmental pollution level for use must be ≤ 2 (in accordance with IEC 60664-1), and should be avoided in environments with dust, oil, and corrosive gases. Otherwise, an enclosure with a protection level of IP54 or higher must be equipped.

（5） Other safety requirements

Cable specifications: Only use copper core wires with a temperature rating of 60/75 ℃ or 75 ℃. Twisted Pair cables require 4 pairs of types (such as Cat5e, Cat6), and PoE module cable length ≤ 3m;

Lid opening restriction: The device casing can only be opened by authorized HIRSCHMANN technicians. Unauthorized lid opening may result in equipment damage or loss of warranty eligibility;
