Chassis Ground Interface

PROPER GROUNDING PROTECTION IS REQUIRED. You must connect the
equipment to the protective earth connection at all times. Use this ground stud
during installation, configuration, and operation.
The AC power interface provides the safety ground.
Use the #10-32 stud (Item 13, Figure 4-5 and Item 3, Figure 4-7) for connecting a common
chassis ground among equipment.

LBC-4000 ON/OFF Power Switch

For units as equipped, an ON/OFF power switch is mounted behind the front panel. To access the
switch, loosen the three front panel thumb screws, slide the front panel out from the chassis, and
then drop down the panel.
Prior to turning on power to the unit, check to ensure that installation is complete, and verify that
the LBC-4000 is connected to the proper prime power source, RF Input, and RF Output.
Turn the switch ON and verify the cooling fan is operational, the LED indicators illuminate as
expected, and the VDF is readable.
