INSTALL POWER CABLE ASSEMBLIES

3.2
See Figure 3 - 1 for power cable assembly installation procedures. The MDR-8000 is internally
wired to accept 20.5 to 60 V dc input power with positive or negative ground. To protect main-
tenance 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.
Do not apply battery power until it is determined that A and
B battery cables with isolated returns and power cables are
wired correctly. With power applied, reverse polarity on wir-
ing (+batt wired to -batt pin on connector) can cause power
supply fuse to blow.
