A: Hot-swapping is permitted only when backplane power is isolated or when operating in non-hazardous location class conditions. Physical keying on the terminal base must be verified prior to module insertion.\u003c\/p\u003e\n\u003cp\u003eQ: What is the mechanical function of the CHAS GND and C terminals on the terminal base? A: The CHAS GND terminal connects directly to the mounting DIN rail to establish a high-frequency noise grounding path for shielded encoder cabling, whereas the C terminal provides a direct return path for DC power.\u003c\/p\u003e\n\u003cp\u003eQ: What operating voltage level does the 1734-VHSC5 inputs accept? A: The 1734-VHSC5 is specifically rated for 5 VDC differential or single-ended logic level encoder and counter inputs.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSecure the two-module assembly onto a standard 35 mm DIN rail, ensuring that the lower rail locking latch engages completely.\u003c\/li\u003e\n\u003cli\u003eRoute shielded signal wires for high-speed counter inputs away from high-voltage AC cables.
