POWER CABLE CONNECTION

3.2
See Figure 3 - 1 for power cable assembly installation procedures. The MDR-8000 is inter-
nally wired to accept 20.5 to 60 V dc input power with positive or negative ground. To pro-
tect maintenance personnel from lightning strikes, the ground system must be integrated
by bonding station ground and dc battery return together. The dc power connectors J1 and
J2 are located on the rear of the back panel. Install power cables as shown.
Short circuiting low-voltage, low-impedance dc circuits can
cause arcing that may result in burns or eye injury. Remove
rings, watches, and other metal jewelry while working with
primary circuits. Exercise caution to avoid shorting input
power terminals.
To protect maintenance personnel from antenna tower light-
ning strikes, the ground system must be integrated by bond-
ing frame ground and dc battery return together.
