The 89477 series cable is manufactured to strict tolerance standards to prevent signal reflection and attenuation. When installing, it is necessary to ensure the cable is routed away from high-voltage lines or inductive load sources to minimize electromagnetic interference. Cross-talk suppression is maintained by the coaxial shielding, which must remain continuous and grounded only at the specified system ground point to prevent noise injection into the -10 VDC gap voltage monitoring loop.\u003c\/p\u003e\n\u003ch3\u003e## Ordering info\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1x 89477-10 Interconnect Cable\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x Technical instruction bulletin\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x Protective connector caps (pre-installed)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eRouting: Secure the cable using cable ties at regular intervals to prevent mechanical fatigue caused by vibration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBend Radius: Maintain a minimum bend radius of 25 mm for the coaxial cable to avoid crimping the center conductor or distorting the dielectric.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConnections: Ensure all connectors are hand-tightened and free of debris or oxidation.

No, field repair of the coaxial cable (splicing or soldering) alters the impedance characteristics and will lead to inaccurate measurements.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the impact of incorrect cable length?
