4.3 System Interconnections

Figure 4.3-1: MXU Console Interconnections

Interconnections between the antennas, power and the MXU console are illustrated in Figure 5.4-1. Each

step numbered in Figure 5.4-1 is discussed below in the following paragraphs.

4.3.1 Building Ground

Step 1. Locate the “Building Ground”. It is extremely important to ground the antenna assembly, surge

protectors, and power outlet to the central building ground. If not properly grounded, a nearby

lighting strike can easily damage the MXU system and can cause personal injury or death. In figure

4.3-1 the building ground is illustrated, in view G, as a ground rod. If any doubt exists as to the

location of the building ground consult with a local certified electrician.

Step 2. Verify the MXU power outlet, view “F” will accept the three prong electrical pug (Line Item 28)

supplied with the MXU shipment. Consult with a certified electrician to verify the power outlet is

properly wired and verify ground is properly connected to the building ground. If the power cord

does not match the power outlet, the user is responsible for securing the correct power cord. Refer

to Pre-Installation Checklist, Check 10, Appendix “A”.
