2.6 Safety notes for installation and maintenance
DANGER
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 brak
-
ing 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.
WARNING
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.
CAUTION
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.
To prevent accidents, injuries and damage to property:
Perform a risk assessment and follow all of the statutory and local safety instructions and accident prevention regulations
when installing or maintaining the system.
Ensure that the AC or DC power supplies are switched off and locked prior to performing any work in the area of the machine.
The deactivation of the output stages or servo drive enable signals is not a suitable means of locking. In the case of a malfunc
-
tion, the drive may accidentally be put into action. This does not apply to drives with the special "Safe Torque Off" feature in
accordance with EN 61800-5-2.
Electronic devices are never completely fail-safe. It is the user’s responsibility to ensure that the system is brought to a safe
state if the electrical device fails.
