Hardware Configuration
Before installing a new ADM, set S1
on the CPU PCBA to the module address and set the jumper
settings (J4-J9) as shown in the system manual. Valid address settings are (5 to E). Jumper settings
(J4–J9) allow ground fault detection to be enabled or disabled. See Table 8 for the jumper setting details.

:
• To ensure proper termination, crimp a ferrule on the end of any conductor that is to be terminated on
a terminal block. The size of the ferrule depends on the size of the conductor used and may be
obtained from suppliers such as Phoenix, Altec, or Weidmuller. The terminals accept a maximum
conductor size of No. 12 AWG and a minimum conductor size of No. 28 AWG.
• Ground fault detection can be enabled only when one speaker loop from each amplifier is being
monitored.
