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
lightning strikes, the ground system must be integrated by
bonding 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 wiring (+batt wired to -batt pin on connector)
can cause power supply fuse to blow.
