Note!
ƒ
Please keep the plastic covers on the connectors for the control connections
and interfaces!
ƒ
Cover unused connections during transport, storage and operation with the
plastic covers to preserve the certified safety engineering features.

Danger!
ƒ
The
X2x
power connector contacts can conduct hazardous voltages if the
motor starter is connected to the mains. Therefore, disconnect the motor
starter before carrying out any work on it.
ƒ
All control terminals feature only basic insulation (single isolating distance)
following the connection of a PTC thermistor (PTC) or a thermal switch (NC
contact):
–
Protection against accidental contact with defective isolating distance can
only be ensured through external measures, e.g. double insulation.
ƒ
To avoid injury to persons and breakdowns, it is essential that the motor
starter is properly earthed via X10!
(
Stop!
Ensure trouble−free operation of the motor starter:
ƒ
Avoid compensating currents via the PROFIBUS cable shield:
–
For this, connect all devices with a 16 mm
2
cable via the FE bolts.
–
Lay cable in parallel to bus cable.
–
Use a copper braid cable to connect the FE bolts with the mounting
surface.
ƒ
Properly lock the connector plugs.
EMC−compliant wiring

Note!
ƒ
Use a copper braid cable to connect the PE bolt with the mounting surface.
ƒ
Separate control and data cables from motor cables.
ƒ
Connect control and data cable shields
at both ends
