\ Alarm connector [ALARM]
This connector is for outputting the alarm signals to the
external system when any problem with the supply volt-
age has occurred inside the CCU or the CCU fan has
stopped.
When the power supplied to the AC fan or DC fan inside
the CCU has been shut down, pins 3 and 4 of this con-
nector are shorted.
If power is supplied to the CCU and any of the DC power
supplies inside the CCU fails to output the supply voltage,
it means that pins 1 and 2 of this connector are shorted.
