SENSTAR OmniTrax - System Grounding

The OmniTrax enclosure
OmniTrax Product Guide Page 85
System grounding
The OmniTrax processor requires a connection to a low resistance earth ground (Senstar
recommends 5
 or less). Install an approved ground rod or ground plate as close to the processor
as possible. Use an approved ground wire to connect the ground rod to the ground lug on the
processor enclosure. Figure 50:
Ground connection details illustrates the OmniTrax earth ground
connection.
Points to remember
• follow all local construction and electrical codes
• install the enclosure above the high water and high snow levels
• install anti-ram bollards in areas with vehicle traffic
• ensure the cable glands and TNC connectors on the bottom of the enclosure are oriented
toward the ground
Note Consult the local electrical code for information about installing a low
resistance earth ground.
