5.7 Alarm Connections
The alarm connections for all rectifiers, breakers, and fuses are factory pre-wired. The MX28B
dc power plant, however, permits the user to program the system alarms in various ways. A
Printed Circuit (PC) board designated “EAA-0075” is mounted in the space above the master
control unit and provides terminal block connection points for alarm outputs and alarm inputs
(Figure 5-8). These cage-clamp terminal blocks are operated by pushing back the lever,
inserting the wire and then releasing the lever to clinch the connection. Recommended wire size
is #28 AWG to #20 AWG.
