This chapter describes the various power, input/output, and
communications modules the DL8000 uses. It also describes how to
install, remove, and wire the modules.
The DL8000 uses a Power Input module to convert the voltage from the
AC power supply to the voltage levels the DL8000 unit's electronics
require and to monitor voltage levels to ensure proper operation. All
DL8000 applications use the 12 volt Power Input module.
The Power Input module has removable terminal blocks for wiring and
servicing. The terminal blocks can accept wire sizes between 12 and 22
AWG (American Wire Gauge).
