2.6 Safety notes for installation and
maintenance
Dangerous electrical voltage!
Prior to performing any maintenance tasks, you need to ensure that the power supply
and the external power supply of the servo drive have been disconnected and secured
against reconnection and that the DC bus has discharged.
During the operation of the servo drive and up to 10 minutes thereafter, the
corresponding connections and an external braking resistor carry dangerous DC bus
voltages. Contact with these voltages may result in serious or even fatal injuries.
Wait 10 minutes prior to performing any work on the connections. Always measure the
voltage with a suitable instrument.
Risk of burns due to hot surfaces!
The servo drive and, in particular, the (external or internal) braking resistor may become
hot during operation. Always wait a sufficient amount of time prior to touching these
parts.
Always use suitable personal protective equipment to avoid severe burns.
Risk of injury for unqualified personnel!
Only personnel who are trained and qualified for working on or with electrical devices are
authorised to install, maintain and repair the servo drive.
