DANGER
Serious risk of injury through electric shock!
Due to the DC link capacitors dangerous voltage may persist at the DC link
contacts "X02" after the servo drive has been disconnected from the mains
supply. After disconnecting the servo drive wait 5 minutes and measure the
voltage at the DC link contacts DC+ and DC-. The device is safe once the
voltage has fallen below 50 V.

motors please note the following:
- Remove all relevant mains fuses.
- Switch off the main system switch and secure it with a lock.

Check the rated voltage and current of the servo drive and the connected
motors.
