14 Safety instructions
Electrical safety precautions
These instructions are for all who install or connect an option module to a drive and
need to open its front cover or door to do the work.
WARNING!
Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur. If you are not a qualified electrical
professional, do not do installation or maintenance work. Go through these
steps before you begin any installation or maintenance work.
1. Clearly identify the work location and equipment.
2. Disconnect all possible voltage sources. Make sure that re-connection is not
possible. Lock out and tag out.
•
Open the main disconnecting device of the drive.
•
If you have a permanent magnet motor connected to the drive, disconnect the
motor from the drive with a safety switch or by other means.
•
Disconnect all dangerous external voltages from the control circuits.
•
After you disconnect power from the drive, always wait 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 close to bare conductors.
5. Measure that the installation is de-energized.
•
Before and after measuring the installation, verify the operation of the voltage
tester on a known voltage source.
•
Make sure that the voltage between the drive input power terminals (L1, L2,
L3) and the grounding (PE) busbar is zero.
•
Make sure that the voltage between the drive output terminals (T1/U, T2/V,
T3/W) and the grounding (PE) busbar is zero.
•
Make sure that the voltage between the drive DC terminals and the grounding
(PE) busbar is zero.
6. Install temporary grounding as required by the local regulations.
7. Ask the person in control of the electrical installation work for a permit to work.
