IT mains type
I Insulation of all active parts from ground or connection of one
point to ground via an impedance R
E
T Exposed conductive parts directly grounded, independent of
grounding of current source (station ground)

Notes on project planning
Risk to damage to devices from voltage arc‐
ing.
NOTICE
For applications with static charging (e.g., printing, packaging) and operation
on IT mains type, use an isolating transformer with U
K
≤ 2.5%.
Voltage increase in the case of ground fault!
In case of a "ground fault" in the IT mains type, higher voltages
against ground (device housing) affect the device as opposed to
error-free operation.
The "ground fault" in the IT mains type is only possible temporari‐
ly with the IndraDrive components.
For operation on the IT mains type, the drive system including
mains filter and mains choke should be electrically separated
from the mains by an isolating transformer.
In this way, the ground fault detection or monitoring can remain
effective in the system.
