Ensure that uninsulated control cabling running nearby does not contact the high-energy suppression paths. If a persistent field ground fault occurs, these clamping elements can undergo structural breakdown, resulting in low-impedance shorts across the supply rails.\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem;\"\u003e\n  \u003cp style=\"color: #9b2c2c; font-weight: bold; margin: 0;\"\u003e\n    CRITICAL WARNING: HIGH VOLTAGE AND DE-ENERGIZATION REQUIREMENTS\n  \u003c\/p\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0.5rem 0 0 0;\"\u003e\n    Completely disconnect, isolate, and lock out all upstream main three-phase AC pathways and secondary DC auxiliary lines feeding the drive converter bay.
