Danger!
Dangerous voltage!
When the mains voltage is switched off, the DC bus is still charged for at least
about 3 minutes.
ƒ
The state of charge is not indicated!
ƒ
On synchronous motors self−discharge only starts after a possible feedback
operation has been completed.
ƒ
Discharging the DC bus in a controlled manner via the brake chopper/brake
resistor requires the external 24 V supply (
^ digital input DI1).
Possible consequences:
ƒ
Death or severe injuries when touching the terminals.
Protective measures:
ƒ
Before starting work on the system check that it is deenergised.
ƒ
Wait at least 3 minutes after switching off the mains voltage.
ƒ
Only remove deenergised devices from the installation backplanes and do
not touch any terminals.
How to proceed:
ƒ
Adjust the setting for the mains voltage/brake chopper threshold to the mains
