Exceeding recommended UCN cable lengths will result in attenuation that cannot be compensated for by this hardware.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Secure the drop tap kit to a control cabinet panel or DIN rail.
