- Secure with screws at a torque of 0.5–0.6 N·m to avoid damage.
‌Wiring‌:
- Connect to a 24V DC power source using shielded twisted wires for noise reduction.
- Ensure proper grounding (resistance ≤1Ω) to minimize interference and enhance safety.
‌Operation‌:
- Power on the module after verifying all connections; monitor for stable operation indicators (e.g., steady green LED).
- Perform regular inspections for dust or corrosion, especially in high-temperature or humid environments.

🔌 General wiring specifications
Power input requirements

Voltage range: Supports 24V DC industrial standard power input with a tolerance of ± 10% (i.e. 21.6-26.4V DC).
Wiring terminals:
L+: Positive input terminal
M: Negative/Ground Terminal (requires independent grounding)
Cable specifications: Use shielded twisted pair cables (cross-sectional area ≥ 1.5mm ²) to suppress electromagnetic interference.
Grounding protection

The grounding impedance should be ≤ 1 Ω, and the grounding wire should be directly connected to the grounding bolt of the equipment casing. It is prohibited to share the same path with the power cable.
Try to shorten the length of the grounding wire as much as possible to avoid forming loop 3.
