1 Advertencias de seguridad (Mandatory Compliance)

WARNING (Risk of Fatal or Severe Injury)

1. Cut off all DC24V power supplies of the system before all installation, alambrado, disassembly and assembly operations. Hot plugging/unplugging of Ethernet cables, terminal blocks and modules is strictly prohibited.
2. The FG grounding terminal must be independently grounded with grounding resistance ≤100Ω to prevent electric shock, communication interference and module burnout.
3. Never connect AC220V or high-voltage cables to I/O or power terminals; this will directly burn the module and cause fire hazards.
4. External fuses must be installed inside the control cabinet to protect the module DC24V power circuit.
5. Only certified electricians are allowed to perform installation and commissioning work.

CAUTION (Risk of Equipment Damage & Maloperation)

1. Tighten terminal screws strictly per standard torque; insufficient torque causes overheating and short circuits, while excessive torque strips threads and damages terminal bases.
2. Communication cables must adopt Cat5e or higher double-shielded STP straight-through cables. Unshielded UTP cables are forbidden.
3. Separate power cables from communication/I/O cables during routing with a minimum clearance of 100mm to avoid electromagnetic interference.
4. Direct installation in environments with heavy dust, condensation or corrosive gas is prohibited; sealed control cabinets are required for protection.
5. Prevent water, metal debris and wire copper scraps from entering the module interior, which will lead to short-circuit burnout.

4 DIN Rail Installation & Removal Steps

4.1 Procedimiento de instalación

1. Confirm the rail is standard 35mm steel DIN rail with firm fixed mounting without shaking.
2. Pry open the upper and lower latches on the module rear side downward.
3. Hook the upper latch onto the top edge of the rail, attach the module to the rail and push upward tightly.
4. Snap the lower latch upward to fully lock the module without looseness.
5. Install rail stoppers at both rail ends to prevent horizontal sliding of modules.

4.2 Removal Procedure

1. Cut off all DC24V power supplies and wait 3 minutes for capacitor discharge.
2. Press the lower latch to pry it downward, lift the module bottom upward to detach from the rail.
3. Remove the module; do not pull cables with brute force.

5 DIP Station Number Setting (Mandatory Adjustment Before Installation)

8-position DIP switch on module front panel for binary station number configuration (intelligent stations 1~120)
