7.5.4 Replacing a Power Module with enabled safety function
DANGER
Danger from touching energized Power Module connections
After switching off the mains voltage, it will take up to 5 minutes until the capacitors in the
Power Module are sufficiently discharged for the residual voltage to be safe. Death or serious
injury will result if energized parts are touched.
● Check that the Power Module connections are in a no-voltage condition after you have
removed the cables from the Power Module.
Procedure
To replace the Power Module, proceed as follows:
1. Switch off the inverter power supply voltage.
2. Remove all cables from the inverter.
3. After 5 minutes, check whether the device is in a no-voltage condition.
4. Release the four Power Modules screws.
5. Remove the Power Module.
6. If a memory card is inserted in the Power Module, remove the memory card and insert it
into the new Power Module.
7. Mount the new Power Module on the Control Unit.
8. Reconnect all of the cables to the inverter.
9. Switch on the power supply voltages again.
10.The inverter reports F01641.
11.Perform a reduced acceptance test.
