18 Safety instructions
Electrical safety in installation, start-up and maintenance
Precautions before electrical work
These warnings are for all personnel that do work on the drive, motor cable or motor.
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.
2. Disconnect all possible voltage sources.
•
Open the main disconnector of the drive.
•
Open the disconnector of the supply transformer as the main disconnector of the
drive does not remove the voltage from the input busbars of the drive.
•
Make sure that reconnection is not possible. Lock the disconnectors to open
position and attach a warning notice to them.
•
Disconnect any external power sources from the control circuits before you do
work on the control cables.
•
After you disconnect the drive, always 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 close to 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 drive module input power terminals
(L1/U1, L2/V1, L3/W1) and the grounding (PE) busbar is close to 0 V.
•
Make sure that the voltage between the drive module UDC+ and UDC- terminals
and the grounding (PE) busbar is close to 0 V.
6. Install temporary grounding as required by the local regulations.
7. Ask for a permit to work from the person in control of the electrical installation work.
