lation work on the AMR.
Do not perform maintenance work on the AMR until the measured voltage of the mo-
tor controller capacitors are below 7 VDC.

Press an E-STOP button.
2
Shut down the AMR by pressing the OFF button on the Operator Panel.
3
Turn the AMR main disconnect switch to OFF position (horizontal).

Probe the appropriate connector pins on the module shown below using a digital multimeter.
Probe the back of the pin 4 (positive) and pin 3 (negative).
Each motor controller is equipped with a capacitor that stores energy. You must check and
make sure that the voltage is less than 7 VDC.
6
After the voltage is less than 7 VDC, verify that the AMR is de-energized by pressing the ON /
OFF button on the Operator Panel and then repeat step 5.
After confirming the voltage remains less than 7 VDC, this procedure is complete.
