When wiring, ensure that hazardous area cables remain physically separated from safe-area cables by at least 50mm to prevent inductive or capacitive coupling. Technical staff should verify that the supply voltage does not exceed the 26.9V working voltage (Uw) during normal operation, as exceeding this limit will cause leakage current through the zeners and may eventually blow the internal fuse.

This dual-channel Zener barrier limits voltage and current to safe levels, ensuring that instrumentation in Zone 0, 1, or 2 remains incapable of igniting explosive atmospheres. While optimized for 24V DC control loops, the Z779 provides indispensable protection for transmitters, solenoid valves, and proximity switches in high-risk sectors such as petrochemical refining and gas processing. By shunting excess energy directly to earth ground, this barrier maintains a secure boundary between the safe control room and the volatile field area.
