Electrical safety precautions
These electrical safety precautions are for all personnel who 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.
Do 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.
•
Open the charging switch if present.
•
Open the disconnector of the supply transformer. (The main disconnecting device
in the drive cabinet does not disconnect the voltage from the AC input power
busbars of the drive cabinet.)
•
Close the grounding switch or switches ([Q9], F259) if present. Do not use
excessive force as the switch has electromagnetic interlocking.
•
Open the auxiliary voltage switch-disconnector (if present), and all other possible
disconnecting devices that isolate the drive from dangerous voltage sources.
•
In the liquid cooling unit (if present), open the switch-disconnector of the cooling
pumps.
•
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. Use a quality voltage tester. If the
measurement requires removal or disassembly of shrouding or other cabinet structures,
obey the local laws and regulations applicable to live working (including – but not limited
to – electric shock and arc protection).
•
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.
