IV. Main Matters (Installation / Wiring / Maintenance)

1. Installation

Environment: Dust-free, dry, free from corrosion, anti-condensation

Heat dissipation: ≥ 50mm above and below, away from heat sources

Grounding: Cabinet independent ground ≤ 4Ω

Hot swapping: Online replacement after disabling software

2. Wiring (28-pin)

Signal: Shielded twisted pair, single-ended grounding (module side)

Cabling: Separate slot from high voltage ≥ 10cm, avoid long parallel runs

Power supply: 24V DC ±10%, reliable connection to GND

3. Configuration and Calibration

Software: ELOP II selects signal type / range / filtering, takes effect after download

Calibration: Once a year; if error > ±0.2% FS, re-calibrate

4. Maintenance and Faults

Status: Green LED = normal, Red = fault; regularly check diagnostic logs

Troubleshooting: Faulty → Wiring / Shielding / Grounding; Channel failure → Replace channel for testing, if abnormal then replace module
