HIRSCHMANN MACH1040 family Full Gigabit Industrial Ethernet Ruggedized Switch

Safety regulations and installation environment requirements

（1） Personnel qualification requirements

Only "qualified personnel" are allowed to operate the equipment. Qualified personnel must meet the following requirements: have received professional training, possess knowledge of safety technical standards related to circuit grounding and identification; Understand potential hazards in the workplace; Master risk prevention measures; Regularly receive retraining.

（2） Mandatory requirements for installation environment

Installation location: It can only be installed in switch cabinets or restricted access areas, and is exclusively accessible to maintenance personnel; Prohibited for use as a desktop device.

Installation method adaptation:

19 inch cabinet installation: sliding/mounting rails are required to support the weight of the equipment and ensure easy cable access; At least one rack space (about 5cm) should be reserved above and below the device for heat dissipation.

Vertical installation on the wall: It must be installed inside a fire-resistant enclosure that complies with IEC/EN 62368-1 standards to avoid the risk of fire.

Environmental parameter threshold:

Temperature: Standard (S) 0 ° C~+60 ° C (+32 ° F~+140 ° F); Expansion type (T/E) -40 ° C~+70 ° C (-40 ° F~+158 ° F), with additional conformal coating for E-type; Storage temperature -40 ° C~+85 ° C.

Humidity: 5%~95% (non condensing state).

Air pressure: up to 2000 meters (795 hPa), higher altitudes require prior consultation.

Pollution level: not exceeding level 2.

Special requirements for hazardous environments (Class 1, Division 2):

Only use models labeled "FOR USE IN CLASS I, DIVISION 2 HAZARDOUS LOCATION".

When using the USB port, it is necessary to install a tool to lock the casing to prevent accidental operation.

It is prohibited to disassemble or replace equipment when it is in a charged state, unless it is confirmed that there is no concentration of flammable gases in the area.

Do not replace any components as it may affect explosion-proof compatibility.

Signal contacts must comply with electrical parameters (Vmax 30V, Imax 90mA, Ci 50pF, Li 2 μ H), cable length must be calculated based on capacitance/inductance parameters (default 60pF/ft, 0.2uH/ft), and wiring must follow NEC NFPA 70 Article 501 standard.

（3） Electrical safety regulations

Power supply safety:

The power supply voltage must be consistent with the equipment nameplate, L-type (24-48VDC), M-type (100-240VAC/110-250VDC), with a voltage range including maximum tolerance (L-type 18-60VDC, M-type 90-265VAC/77-300VDC).

The power cord needs to use copper wire with a cross-sectional area of not less than 1mm ² (North American AWG16); The cross-sectional area of the protective conductor shall not be less than the power supply wire and shall not be less than 1.0mm ² (AWG16).

The power supply should be equipped with easily accessible disconnect devices (such as switches, plugs) and clearly labeled; The outer conductor of AC power supply or the positive conductor of DC power supply should be equipped with fuses (L-type 6.3A slow melting, M-type 2.5A slow melting), and double fuses are required when the neutral/negative wire is not grounded.

Grounding requirements:

The device is grounded through an independent grounding screw on the back, and the grounding operation must take priority over other cable connections; The grounding cable needs to be operated last when disconnecting.

The shielded grounding wire of the twisted pair cable should be connected to the front panel of the equipment, and the risk of short circuit should be avoided during connection.

Cable and connection safety:

The cable needs to be designed for stress relief to avoid twisting, poor contact, or interruption caused by mechanical stress; Follow the requirements of sections 522.6, 522.7, and 522.13 of DIN VDE 0100-520:2013-06 standard.

At least 10cm of space should be reserved in front of the equipment ventilation duct to ensure heat dissipation; Do not insert sharp objects into equipment or wiring terminals, and do not touch live terminals.

When the device is running or just turned off, the casing may be hot. Do not touch it to avoid burns.

Complete installation process

（1） Preparation before installation

Packaging content inspection: Confirm that it includes 1 device, 2 pre installed brackets and fixing screws, 1-2 3-core power supply terminal blocks (according to model), 1-2 2-core signal contact terminal blocks (according to model), and 1 safety and general information sheet; Check all components for any transportation damage.

Tools and accessories preparation: Prepare suitable screwdrivers, torque wrenches (power terminal 0.51Nm, signal contact terminal 0.34Nm), cables that meet specifications (power line, ground wire, data line), and optional HIRSCHMANN compatible SFP optical modules.

Installation location confirmation: Ensure that the installation location meets environmental parameters, space requirements, and power supply conditions match the equipment.

（2） Core installation steps

1. Optional steps: Install SFP optical module

Remove the SFP optical module from the shipping packaging and remove the protective cap.
