Additional Instructions And Notes; Grounding - ABB ACS580MV Hardware Manual

12 Safety instructions
5. Measure that the installation is de-energized.
•
Use only instrumentation (e.g., meters, oscilloscopes, etc.) intended for high
voltage measurements.
6. Always discharge equipment and verify that it is neither electrically alive nor thermally
hot.
7. Always install temporary grounding as required by the local regulations.
8. Ask for a permit to work from the person in control of the electrical installation work.

Additional instructions and notes


•
Do not connect the bypass- drive system to a voltage higher than what is on the rating
plate.
•
The motor cable terminals of the bypass- drive system are at a dangerous voltage
when the input power is on, regardless of whether the motor is running or not.
•
External wiring can supply dangerous voltages to the terminals of relay outputs.

Grounding


•
Always ground the bypass- drive system, the motor and adjoining equipment. Assure
that the drive is grounded on both sides, i.e. on supply and motor side. This is
necessary for the personnel safety. Proper grounding also reduces electromagnetic
emission and interference.
•
Make sure that the cross-section of the grounding conductors is sufficient. See the
ACS580MV Engineering Guideline. Obey the local regulations.
