The AC connections on the shelf are made via rear accessed
compression style terminal blocks. See
Figure 2-4
. Connect
the first line/hot to L1, the second line or neutral to L2/N and
the AC ground to GND. These terminal blocks will accept up
to a maximum of 10 AWG wire, and should be torqued to
6 in-lbs.
The power supply is connected to the SSPA via an alarm
cable, part number L205676-1, supplied with the unit. This
cable connects between the Alarm port of the power supply
and the PS M&C Port (J12) of the SSPA. See
Figure 2-5
.
Each power supply module has an alarm output. For logic reporting purposes, the
alarm outputs for power supply modules 1 and 2 are linked, as are those for power
supply modules 3 and 4. The power supply alarms are monitored by the SSPA Chassis
monitor and control system. This provides local and remote alarm reporting in the
event of a power supply module failure.
The module alarms are open-collector signals with a high impedance state = fault logic
level. Under normal operation, the alarm outputs are in an open collector logic low
state.
The alarm connection from each power supply chassis is parallel connected by
supplied cable L206406-1. This cable also contains a current sharing line between the
two power supply chassis.
