After Connecting-Up, The Following Points Should Be Checked/Tested; Connecting The Ground Conductor; Screw-In Depth And Tightening Torque - Siemens SINAMICS S 1PH7 Configuration Manual

After connecting-up, the following points should be checked/tested

● The inside of the terminal box must be clean and free of any cable pieces
● All of the terminal screws must be tight
● The minimum air distances must be maintained
● The cable glands must be reliably sealed
● Unused cable glands must be closed and the plugs must be tightly screwed in place
● All of the sealing surfaces must be in a perfect condition

Connecting the ground conductor

The ground conductor cross-section must be in full conformance with the installation
regulations, e.g. acc. to IEC/EN 60204-1.
For shaft height 225, the ground conductor must be additionally connected to the motor
bearing shield. There is a terminal lug for the ground cable at the designated connection
point. This is suitable for connecting multi-conductor cables with cable lugs or flat cables with
the appropriately prepared conductor end.
Please note the following when connecting-up:
● The connecting surface must be bare and must be protected against corrosion using a
● There is a spring washer and normal washer underneath the screw head
● The minimum necessary screw-in depth and the tightening torque for the clamping bolts
