Connecting AC inductive loads directly to these terminals will result in permanent semiconductor failure. When driving external DC relays or solenoid coils, an external flyback diode must be installed across the load to suppress back-EMF spikes. Additionally, the unit is rated for 12 to 24 VDC; verify that power supply ripple does not exceed 20% to prevent erratic display behavior or micro-reset events.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eAlways configure the input mode setting (sinking vs. sourcing) in the function parameter menu prior to connecting your sensors. An incorrect input logic configuration will prevent the unit from registering input pulses even if the physical sensor is functioning correctly. To minimize high-frequency electromagnetic interference, route all signal input lines (CP1, CP2, and Reset) in a separate grounded metal conduit away from high-current AC power cables.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\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 0 0.5rem 0;\"\u003eCRITICAL WARNING\u003c\/p\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0;\"\u003eIsolate and lock out all external power sources before executing terminal connections.
