2.4.3 Grounding the Base Station
Vecima recommends grounding the base station using one of the following procedures depending on your configuration.
If you are unsure which procedure to use, use procedure B.
Procedure A: Grounding the base station so that the building and the tower share the same earth ground:
1. Connect the chassis of the OBR5000B to the tower via the grounding lug on the back of the unit. See “Grounding
the Base Station” on page 2-11.
2. Use a shielded CAT5 cablefeed to connect the OBR base station to the surge suppressor.
3. Use an inline surge suppressor for all OBR5000B cablefeed installations. Connect the shield of the cablefeed to
the ground lug of the surge suppressor. The purpose of the surge suppressor is to shunt to ground any over volt
-
age [>60] transients that may be induced on the CAT5E cablefeed via lightning or other high voltages.
