1 Mandatory Safety Requirements (Must Be Followed)

⚠️ Critical Hazard Warnings

1. Cut off all 24 V power before any installation, wiring removal or disassembly. Hot plugging/unplugging of M12 connectors is strictly prohibited, as it will burn port driver chips.
2. The power supply is SELV/PELV safety extra-low 24 VDC; connection to 220 VAC or 380 VAC mains power is forbidden.
3. The metal mounting base must be reliably earthed to prevent electrostatic discharge and surge damage to Ethernet and IO-Link channels.
4. For food/washdown applications, avoid direct high-pressure water spraying onto connector roots. Select AL1307 (IP69K) for long-term washdown exposure.
5. Ambient Temperature Range: Operating -25℃ ~ +60℃; Installation temperature ≥0℃ to avoid seal hardening and water ingress at low temperatures.

2 Pre-Installation Inspection & Tool List

2.1 Unboxing Inspection

1. Check the AL1304 unit for cracks, dents and deformed connectors; confirm FKM sealing rings are intact and undamaged.
2. Standard contents: Main unit, printed quick installation manual. Cables and dust caps are not included and must be ordered separately.
3. Verify model marking AL1304, confirm 4 Class A IO-Link channels and dual D-coded Ethernet ports.

2.2 Instrumente necesare

Cheie dinamometrică (0.5～3 N·m), M5 bolts, flat washers/spring washers

14 mm open-end wrench (for tightening M12 connectors)

3.2 Metode de montare: Wall / Machine Body Mount (No DIN Rail Clips)

1. Two mounting through holes on the top and bottom rear of the unit; secure with 2 × M5 bolts + flat washers.
2. Standard tightening torque: 1.8 N·m. Excessive torque is forbidden to avoid housing deformation and seal failure.
3. Mounting Surface Requirements: Flat metal plate free of burrs and oil contamination. Max tilt angle ≤90°. Do not mount upside down with connectors facing upward (risk of water pooling ingress).
4. Cerințe de împământare: The two M5 mounting bolts also serve as unit earthing terminals; the metal base shall connect to protective earth PE. For non-metallic mounting plates, run a separate earthing wire to the PE busbar.

3.3 Mounting Clearance Requirements

Reserve ≥30 mm vertical clearance above and below the unit for heat dissipation; ≥20 mm side clearance to prevent heat accumulation.

Keep a minimum distance of 150 mm from inverter and servo power cables to reduce electromagnetic interference.

2. Loosen all M12 connectors with a 14 mm wrench; do not pull cables forcibly.
3. Loosen the two rear M5 mounting bolts and remove the unit.
4. Install port dust caps immediately after disassembly to protect sealing rings.

10 Installation Prohibitions & Fault Prevention

❌ Forbidden: Mount unit upside down with connectors facing downward (water pooling into sockets)

❌ Forbidden: Tighten fixing bolts above 1.8 N·m; housing cracking and water leakage will occur

❌ Forbidden: Hot plug/unplug M12 connectors; communication chips will burn out

❌ Forbidden: Parallel close routing of power cables and IO cables, causing communication packet loss

❌ Forbidden: Connect X1 and X2 ports to the same switch, breaking network isolation security

❌ Forbidden: Long-term outdoor operation without dust caps; dust will cause port short-circuits

Common Installation Fault Prevention:

1. Frequent communication disconnections: Check connector torque, shield earthing and separation distance from power cables
2. Persistent port short-circuit alarms: Verify IO-Link sensor wiring and ensure load ≤300 mA
3. PROFINET device not detected: Check GSDML file, IP address, device name and D-coded Ethernet cable
4. Failed IoT data upload: X2 uses an independent network segment with no IP conflict with the PLC network

11 Original Optional Accessories (Ordered Separately)
