Parameter values can be updated over the onboard Modbus\/Profibus fieldbus port, provided the controller possesses valid flash write authorization levels and the main control loop remains in a safe monitoring state.\u003c\/p\u003e\n\u003cp\u003eQ: What mounting configurations are permitted to maintain the IP55 ingress rating?\u003c\/p\u003e\n\u003cp\u003eA: The module supports mechanical installation across defined mounting positions M1 through M6 on standard DIN rails inside sealed enclosure assemblies.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eObserve the following procedures when installing and wiring the ground fault monitoring module:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003ePower De-energization: Lock out and tag out all 380 VAC power lines feeding the target control enclosure. Verify the absence of potential using a calibrated multimeter prior to handling conductor terminals.\u003c\/li\u003e\n\u003cli\u003eDIN-Rail Mounting: Snap the module onto an omega-profile 35 mm DIN rail in any approved mounting orientation (M1 to M6). Ensure the rear metal locking clip fully engages the rail.\u003c\/li\u003e\n\u003cli\u003eGrounding \u0026amp; Shielding: Connect the module ground terminal directly to the main copper earth busbar using a short, low-impedance conductor.
