Proper shield grounding of the MS/TP cabling can help minimize the risk of 
communications problems and damage to equipment because of transient 
voltage spikes (for example, lightning strikes). 

Follow these guidelines for grounding MS/TP cable shields:

• Each transceiver MS/TP segment should have a single point of shield 

ground, preferably as close to the middle of the cabling run as possible. 

• Do not ground the MS/TP shield to an AZW-5000 GND terminal. 

• Do not ground both ends of a shield. Differences in potential between 

the grounds may induce current on the shield, causing interference.

• At ungrounded, exposed shield points, tape back the shield to the wire 

jacket or, for optimum transient shunting, use 100V gas discharge tubes 
or 120V MOVs between the shield and ground.
