5.10 EARTH GROUNDING
Here is a detailed description of the Earth Ground connection path:
1. The input power cable assembly connects CONN4 to the mains power.
2. Refer to the LKAT Plus System Wiring Diagram and wire system accordingly.
3. The earth ground wire connects from CONN4 to the FLTR1 metal case only. The FLTR1
metal enclosure is not connected to copper foil traces on the power supply PC Board
assembly, the steel standoff inserts or the steel PCB mounting bracket.
4. The Earth Ground connection is only used to shunt common mode noise to earth.
IMPORTANT NOTE
There is no electrical connection from any part of the LKAT Main PCB or its optional
daughter PCBs to Earth / Chassis ground or the steel PCB mounting bracket or panel.
There is no electrical connection between the steel PCB mounting bracket or panel to
Earth Ground.
5.11 CONFIGURING THE LOW PASS FILTER
The LKAT Plus System includes a two pole configurable low pass filter. This filter may be
enabled without affecting the scaling of the output in the pass band. The frequency response
of the LKAT Plus without the low pass filter activated is shown in Figure 3.1.
Refer to the Main pc board assembly drawing at the end this manual.
