Procedure B: Grounding the base station so that the building and the tower use different earth grounds:
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 two inline surge suppressors, one for all OBR5000B cablefeed installations at the base of the tower and
another for the first surge suppressor and the WES800. 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 voltage [>60 V] tran
-
sients that may be induced on the CAT5E cablefeed via lightning or other high voltages.
