Safety instructions
WARNING
Danger to life as a result of hazardous voltages when connected to inadequately grounded
line supplies
In the case of a fault, connecting a motor to an inadequately grounded line supply can
result in death, severe injury and motor damage.
•
Connect motors, as part of the drive system, to TN and TT line supplies with a grounded
neutral point or to IT line supplies.
•
Ensure that the SINAMICS devices and motors are compatible with the residual current
device according to EN 61800-5-1 before you connect the devices and motors to the
line supply using residual current devices (RCDs).
•
For line supplies with grounded line conductor, e.g. TT line supplies, use an isolating
transformer with grounded neutral point (on the secondary side) between the line supply
and the drive system, so that the motor insulation is not overstressed.
•
When connected to IT line supplies, a monitoring device must signal the first fault
between an active part and ground. Remove this fault immediately.
