5.2 Connecting the Earth Ground and the 12 VDC Power
The EntraGuard Platinum panel requires 12 VDC power at 750 mA. You must make a quality earth ground connection to
the controller prior to connecting the DC power lines. The earth ground provides protection for the controller and ensures
the best possible operating conditions. Possible sources for earth ground are a ground rod, a cold water pipe, a steel
building frame, the electrical system ground at the breaker/fuse box, or the telephone system ground. The earth ground
connection should be located as close as possible to the EntraGuard Platinum controller. Use the information in Table 1
and Figure 6 to make the earth ground and power connections.
