OPTIMOD INSTALLATION

Power Ground
•
Ground the 6200 chassis through the third wire in the power cord. Proper grounding
techniques never leave equipment chassis unconnected to power/earth ground. A
proper power ground is essential to safe operation. Lifting a chassis from power
ground creates a potential safety hazard.
Circuit Ground
To maintain the same potential in all equipment, the circuit (audio) grounds must be
connected together:
•
Circuit and chassis ground should always be connected by setting the 6200’s GND
LIFT
(Ground Lift) switch to its “CHASSIS GROUND” connect position
.
•
In high RF fields, the system is usually grounded through the equipment rack in
which the 6200 is mounted. The rack should be connected to a solid earth ground by
a wide copper strap — wire is completely ineffective at VHF because of the wire’s
self-inductance.
