2.4 Installing the Grounding Apparatus
Install the grounding apparatus to protect the OBR5000B from lightning strikes and power surges. Ground the base
station to the earth ground to protect from lightning strikes. Use the surge suppressor to shunt to ground any
over-voltage [>60 V] transients that may be induced on the CAT5E cablefeed via lightning or other high voltages.
2.4 Installieren der Erdungsvorrichtung
Installieren Sie die Erdungsvorrichtung, um die OBR5000B gegen Blitzschlag und Stromstösse zu schützen. Erden Sie
die Basisstation für den Schutz gegen Blitzschlag. Verwenden Sie den Überspannungsschutz, um Überspannungen
[>60 V] zu überbrücken, die in der CAT5E-Zuleitung durch Blitzschläge oder andere Hochspannungen verursacht
werden können.
2.4.1 Lightning Protection
The OBR5000B has a built in lightning surge suppression mechanism to protect it against damage from lightning strikes.
Assembling the OBR5000B Base Station Grounding
Attach the earth ground to the grounding lug located on the base station.
Provided parts:
• 1 x 5/8 inch washer
• 1 x 1/4 inch grounding lug
Required parts:
• 1 x #6 AWG grounding wire assembly of sufficient length to connect the OBR to the tower’s earth ground bus
• 1 Size 11 Wrench (11mm or 7/16 inch)
To assemble and attach the ground lug:
1. Locate the grounding point on the OBR5000B. This is at the bottom of the OBR, to the right of the Vecima sticker.
2. On the grounding lug, assemble the grounding combination in the following order:
Lug > Washer > Grounding Assembly > Washer.
3. Screw the combination into the OBR at the grounding point.
4. Attach the assembly to the lightning grid or the antenna.
