Chapter 8 Compliance with Explosion proof Zones (ATEX/IECEx)

For EAGLE One equipment (models with ATEX or UKEX labels) used in Zone 2 explosive gas environments, the following special conditions must be observed:

Temperature level T4: Standard type (S) ambient temperature 0~+60 ° C; Extended type (T/E) -40~+70 ° C.

Shell protection: The equipment is open and needs to be installed in cabinets with IP54 or higher.

USB interface restrictions: USB connectors are only allowed for temporary use and are prohibited from plugging or unplugging USB devices in explosive environments (connection or disconnection may cause explosions). The USB interface is only allowed to be used in known non hazardous areas.

Fault contact parameters: The relay contact is a sealed device, with a maximum switching current of 1A (resistive load) and a maximum voltage of 60V DC or 30V AC, SELV.

Grounding wire requirement: The cross-sectional area of the protective grounding wire should be at least the same as that of the power supply line.

Chapter 9 Environmental Monitoring and Maintenance

Temperature monitoring: CLI/GUI displays the internal temperature of the device, which is about 20 ° C higher than the ambient temperature (5cm away from the device). If the internal temperature exceeds the threshold (expansion type ≤ 90 ° C, standard type ≤ 85 ° C), the signal contact may trigger an alarm.

Relay maintenance: Relays are naturally worn components, and the degree of wear depends on the switching frequency. The resistance of the closed contacts should be checked regularly.

Firmware updates: Regularly visit Hirschmann's official website to check for software updates, obtain new features, and security patches.

Ventilation inspection: Regularly check whether the ventilation holes are blocked according to the degree of pollution on site.

Chapter 10 Disassembly and Disposal

Dismantling sequence (strictly follow):

Disconnect all data cables

Turn off the power supply voltage

Disconnect the signal terminal and digital input terminal

Finally disconnect the grounding wire (the grounding wire must be removed last)

DIN rail disassembly: Insert a screwdriver horizontally into the locking groove, pull down, and lift the bottom of the device outward away from the rail.
