2.7 Equipment Ground
The FAX transmitter is equipped with a RF/Safety ground lug connection on the upper left rear panel, see Figure 2 ‐
2. When shipped without a rack, this safety ground must be connected to either the ground bar/strap inside the
rack or directly to the site ground system. A 2" wide copper ground strap is recommended.
Figure 2-2 FAX RF/Safety Ground Connection
When FAX transmitters are in a Harris Broadcast cabinet, there will already be a copper ground strap connected to
the copper ground buss bar/strap that runs down the left side of the cabinet (when viewing from cabinet rear). The
exciter will also be grounded to this buss bar as well. The rack mount cabinet buss bar/strap must be grounded to
the site ground system. A minimum 2" wide copper ground strap is recommended. The strap should be attached to
the site ground system at the bottom of the cabinet copper ground buss bar.

Caution
WHEN INSTALLING ANY ADDITIONAL EQUIPMENT IN THE TRANSMITTER
RACK, BE SURE TO CONNECT A SEPARATE GROUND WIRE FROM EACH
COMPONENT TO THE BUSS BAR. NEVER RUN "DAISY CHAIN" GROUND
WIRES ACROSS MULTIPLE COMPONENTS AND THEN GROUND TO BUSS
BAR. THIS CAN CREATE A POSSIBLE GROUND LOOP.
