360-degree grounding is required. 3
Line contactor (F250) 4
Common mode filter (E208 for frames R6 to R9). Standard in frames R10 and R11. 5
du/dt filter (E205) 6
Use a separate grounding cable if the shield does not meet the requirements of IEC 61439-
1 and there is no symmetrically constructed grounding conductor in the cable. 7
Drive module 8
Note: If there is a symmetrically constructed grounding conductor on the motor cable in addition
to the conductive shield, connect the grounding conductor to the grounding terminal at the drive
and motor ends.
Do not use an asymmetrically constructed motor cable. Connecting its fourth conductor at the
motor end increases bearing currents and causes extra wear.
*) Switch-disconnector or molded case circuit breaker (F289) and separate fuses in frames
R8 to R11.
**) Output terminals U2, V2 and W2 are included with E205 and in frames R10 and R11.
