Connecting the AC Power Source and Earth Ground
NOTE: If you are using DC power as the primary power source, go to the next section,
“Connecting the DC Power Source.”
Perform the following procedure to connect the AC power source to the Beacon 800.
WARNING: Verify that the power source is unplugged or turned off at the power
source end before you continue with this procedure.
1. Locate the AC terminal strip (see Figure 1 on page 4).
2. Install an appropriately rated cable bushing or conduit in the right-most conduit hub on
the bottom of the Beacon 800 housing.
CAUTION: Only use the four factory installed conduit hubs on the bottom of the housing
for wire entry into the housing. Do not drill the housing for any reason. See
“Routing Wiring Into the Beacon 800 Housing” on page 12 for more
information.
3. Guide the AC power cord or wires in conduit through the right-most conduit hub on the
bottom of the Beacon 800 housing.
CAUTION: Do not route power and detector head wiring through the same conduit hub.
The power wiring may disrupt the transmission of the detector head signal to
the monitor.
4. Connect the AC power wires to the AC terminal strip and the earth ground wire to the
# 10 ground stud as shown in Figure 6.
