Wireless Compatible Wiring Tips for ZCEBOX Plastic Distribution Box Junction Boxes in Industrial Internet of Things (IIoT) Scenarios

1. 1.Wireless Compatibility + Signal Penetration Optimization Design

• Core Selection: Prioritize ZCEBOX IIoT-specific wireless compatible models (dielectric constant ≤2.5, wireless signal penetration rate ≥92%), with box body made of modified PP + glass fiber composite material (low dielectric loss, no shielding of radio frequency signals), flame retardant grade UL94 V-0, temperature resistance -30℃~85℃, adapting to complex industrial workshop environments;

• Wiring Layout: Divide the box into "wired area (power/bus wiring)", "wireless module area (LoRa/WiFi module installation)" and "signal conversion area (protocol converter wiring)"; reserve ≥5cm unobstructed space in the wireless module area, keeping it away from metal components (spacing ≥3cm) to avoid signal shielding; separate strong electricity (220V power supply) and weak electricity (sensor signals/wireless control lines) with non-metallic partition plates (spacing ≥8cm) to reduce electromagnetic interference on wireless signals;

• Wire Adaptation: Use IIoT-specific low-loss wires (insulation layer made of PE material, dielectric loss tangent ≤0.001); sensor signal wires (4-20mA/0-10V) have a diameter ≥0.75mm²; wireless module power supply wires adopt low-ripple wires (ripple factor ≤5%) to avoid signal packet loss caused by power supply interference.

2. 2.Modular Compatibility + Remote Operation and Maintenance Optimization

• Multi-Protocol Compatibility: Reserve 3 sets of modular installation slots in the box, supporting ZCEBOX quick-plug protocol conversion modules (seamless switching between LoRa/WiFi/4G); select anti-misinsertion universal terminals (adapting to wiring of different protocol devices); uniformly mark wires according to "red = power positive pole, black = power negative pole, yellow = signal transmission", combined with laser-etched protocol marks (e.g., "LoRa Module") for quick distinction of device types;

• Remote O&M Adaptation: Reserve a wireless module antenna interface (IP67 waterproof design, adapting to SMA connectors) on the box; when the antenna is external, connect it through a dedicated waterproof extension cable (length ≤3m, signal attenuation ≤3dB); built-in micro status indicators (three-color display for power/signal/fault), supporting remote viewing of junction box operation status through a gateway and quick problem location in case of failure;

• Expansion and Protection: Reserve 2 sets of redundant wiring terminals in the box, allowing direct access when adding new sensors (no need to modify original wiring), supporting quick plugging of ≤1.5mm² wires; the box has an IP66 protection grade; install waterproof quick connectors (suitable for 2-4mm² wires) at wiring holes; seal joints with silicone sealing rings to resist dust and oil contamination in workshops; select gold-plated anti-oxidation terminals (contact resistance ≤5mΩ) to ensure connection stability under long-term low-power operation.
