4.7 Connecting the power supply to the
controller
Connect the power supply to the POWER 7-pin pluggable screw
connector.
Figure4.7: Location of the power supply connector
Connect an external power supply (10 - 30Vdc) for the
controller at pin 1 (positive) and pin 3 (0V) of the pluggable
screw connector.
If an uninterruptible power supply (UPS) is used, the relay
output for power good signals from the UPS is connected to the
following pins:
– pin 4 and 7 for power good AC
– pin 5 and 7 for power good Battery
– pin 6 and 7 for power good DC
Otherwise these pins must be short-circuited.
Notice!
The battery status is checked every 5 minutes by the power
supply unit (APS-PBC-60 or APS-PSU-60).
As the battery charging/discharging levels tend to vary, the
AMC2 provides information about the battery status every 10
minutes. This feature allows a more reliable battery status
information.
