IV. Operating Notes

Pre-Installation Preparation: Verify model and order number, confirm compatibility with system firmware version; inspect module for physical damage; measure 24 VDC power to ensure it is within ±10% range; prepare anti-static wrist straps, insulated tools and shielded communication cables.
Electrostatic Protection: Operators must wear grounded anti-static wrist straps during installation, removal and maintenance. Idle modules must be stored in anti-static packaging; direct contact with circuit boards is strictly prohibited.
Unauthorized Modification Prohibited: Replacement of non-original components, firmware modification or protection setting adjustment are forbidden, as these will void the warranty and may cause safety incidents.
Communication Cabling: Maintain a spacing of ≥30 cm between analog signal cables and power cables; use shielded twisted-pair cables for communication, with termination resistors properly installed on RS485 buses.
Fault Troubleshooting: When the module alarms, first stop relevant control processes and disconnect power. Prioritize checking external factors such as power supply, communication and wiring. Hot-plugging is strictly prohibited. Contact ABB official technical support immediately if issues cannot be resolved.
Environmental Control: Avoid moisture, condensation, corrosive gases and strong electromagnetic interference. Strictly maintain operating temperature between -25℃ and +60℃; derate accordingly when altitude exceeds 1000 m.
