Note
When connecting a 24 V power supply to the AMS 6500, connect the DC side of the power
supply to the AMS 6500 before connecting the AC side of the power supply to AC line power.
4. Secure the power cable to the side of the enclosure with a cable tie-down.

6.8 Eddy Current sensor: -24 V power supply
The power input connector for Eddy Current sensors is located on the A6500-M-RTRM.
When using Eddy Current sensors, feed in a -24 V sensor supply at this connector. This
connector then supplies all the -24 V sensor supply terminals on the termination panel.
The supply terminals at each channel have built-in auto-resetting breakers to protect
against a short circuit on one channel disrupting the power supply for all channels.
Note
The AMS 6500 performs an internal test to verify that -24 V power is connected. If a -24 V supply is
not connected, the CPU Status LEDs on the CPU, and the Status LED on the left side of the
termination panel will turn from green to red. If Eddy Current sensor power is not required, this
internal test can be disabled by installing a jumper on the termination panel at the pins labeled -24
V Disable.
