Safety regulations

(1) General safety requirements

Anti electric shock: The equipment casing is grounded, and sharp objects are prohibited from contacting the terminals. Only qualified personnel are allowed to operate.

Anti overheating: Keep the ventilation duct unobstructed, reserve a space of ≥ 10cm around the equipment, and avoid touching the casing during operation.

Fireproof: If the power supply does not meet the requirements of Class 2/LPS, it needs to be installed in a metal/flame-retardant plastic shell (V-1 level).

(2) Compliance with hazardous environments

Certification type applicable standard environmental parameters

ATEX EN IEC 60079-0/7/15 Temperature Class T4, Operating Temperature -40~+45 ℃

IECEx IEC 60079-0/7/15 Explosion proof Class II 3G Ex ec nC IIC T4 Gc

Class I Division 2 ANSI/ISA 12.12.01 Groups A-D, ambient temperature -40~+70 ℃

Special requirements: Only temporary connections to USB/V.24 interfaces are allowed in hazardous environments. The connector must be plugged and unplugged in a power-off state, and the signal contact current is limited to 100mA.

(3) Power supply and wiring safety

Power supply requirements: redundant input (P1/P2), DC power supply needs to be grounded to the negative pole, AC power supply needs to be isolated and grounded; Class 2 power supply is required in North America.

Wire specification: Copper wire (75 ℃), terminal supports up to 2.5mm ² (AWG 12) wire.

Shielding grounding: The shielding layer of twisted pair cables needs to be connected to the grounding terminal of the front panel of the equipment to avoid short circuits.

Installation process

(1) Preliminary preparation

Packaging inspection: Confirm the basic module, terminal block (4-pin/6-pin), label, and installation manual are included.

Label filling: Fill in the device name, MAC address, IP address, and other information and paste them on the surface of the device.

(2) Hardware installation steps

Media module/SFP installation: Remove the protective cap, align with the slot, insert and tighten the screws; The SFP transceiver needs to close the latch until it is securely fastened.

DIN rail installation: snap the sliding device onto the rail, press the bottom lock to fix it, and reserve a space of ≥ 10cm up and down.

Grounding: Grounded through DIN rails or dedicated grounding screws, with grounding wire specifications consistent with the power supply wire.

DIP switch configuration:

4-pin DIP switch (MS20/MS30 basic module): controls redundancy manager (RM), ring port selection, standby mode, and configuration priority.

3-pin DIP switch (MS20/MS30-… E…): The function is the same as a 4-pin switch, without a priority switch configured (all three keys are ON for software configuration).

(3) Wiring process

Power wiring: 4-pin terminals (P1/P2:+24V, 0V), 6-pin terminals (MS30-… E…: integrated power and signal contacts).

Signal contact wiring: Potential free relay contacts, supporting up to 1A/60V DC for remote diagnosis.

Data cable connection: Twisted pair cables should use Cat5e or above, and fiber optic cables should be matched with port types (SX/LX/LH) to avoid mixing.

(4) LED display configuration

Display mode switching: Press the “SELECT” button for ≥ 2 seconds to switch the port LED display meaning (link status, duplex mode, rate, etc.).

Device status LEDs: P1/P2 (power), RM (redundant), RUN (running), RL1/RL2 (signal contacts).

Basic configuration and maintenance

(1) Initial configuration

IP configuration method: Supports DHCP/BOOTP, V.24 interface (CLI), AutoConfiguration Adapter, HiView software.

Default account: admin (read-write permission, password private), user (read-only permission, password public). The password needs to be changed for the first login (≥ 8 characters, including uppercase and lowercase letters/numbers/special characters).

Core default settings: RSTP enabled, ring redundancy disabled, port auto negotiation enabled, V.24 baud rate 9600.

(2) Maintenance and disassembly

Daily maintenance: Regularly check relay contact resistance, software updates (downloaded from the official website), and clean ventilation ducts.

Disassembly steps: Disconnect the data cable → Cut off the power supply → Remove the terminal block → Press the guide rail lock to remove the device; SFP disassembly requires opening the latch and pulling it out.
