Connecting Signaling Contact X3 - Siemens SINAMICS S120 System Manual

Voltage Protection Module (VPM)
6.7 Electrical connection
For operation on a High Frequency Drive, also observe the following:
• There can be only one spur line to the Voltage Protection Module.
• Three ferrite rings are applied to each motor cable (type: EPCOS/TDK B64290L0022X065).
• The shrink tubing used must be suitable for temperatures of up to 135 °C, at least.
An installation sequence for individual conductors is outlined below. It is particularly relevant for
larger cross-sections.
Preparation
The following preparations must be made before setting up connections:
• Loosen the 4 screws on the cover of the housing, so that the cover can be moved into the
cutouts.
• Move the enclosure cover to the point where the cutout widens out so it can be lifted over the
screw heads.
• Secure the cable glands for the signal cable and the power cables to the enclosure cable
entries of the Voltage Protection Module.
• Remove 300 mm of the cable sheath of the power cables and expose the shield to match the
enclosure gland being used.
• Remove the insulation at the ends of the individual conductors and attach cable lugs.
• Attach the signal cable to X3 and secure the cable with cable ties inside the Voltage
Protection Module.
