Hardware overview
Primary parts of the AVR. Refer to the User Manual for more information.
Obey these safety precautions before you do work on the system:
1. Clearly identify the work location and equipment.
2. Disconnect all possible voltage sources. Make sure that connection is not
possible. Lock out and tag out.
• Open the main disconnecting device of the AVR.
• Disconnect any external power sources from the control circuits before
you do work on the control cables.
• If you have a permanent magnet generator connected to the AVR,
disconnect it from the AVR with a safety switch or by other means.
• After you disconnect the AVR, wait for 5 minutes to let the intermediate
circuit capacitors discharge before you continue.
3. Protect any other energized parts in the work location against contact.
4. Take special precautions when you are near bare conductors.
5. Measure that the installation is de-energized.
• Use a multimeter with an impedance of at least 1 Mohm.
• Make sure that the voltage between the AVR input power terminals
(PWR L1, PWR L2, PWR L3 and PWR L4) and the grounding terminal (PE)
is near 0 V.
• Make sure that the voltage between the AVR output terminals (IE+ and
IE-) and the grounding (PE) is near 0 V.
