6.1.4 Terminal box
The type designation of the terminal box for connecting the power cables can be found in the
technical data. An illustration can be found in Chapter "Spare parts" (Page 109).
The maximum conductor cross-section that can be connected and the permissible cable
external diameter are listed in the "Technical data and drawings" section. The connecting
cables can be sealed and secured at every entry point into the terminal box, using the sealing
insert supplied.

6.1.5 Connecting the grounding conductor
The grounding conductor cross-section of the machine must be in full conformance with the
installation specifications and to EN 60204-11.
Table 6-2 Determining the cross-section of the grounding conductor
External conductor cross-section S Cross-section of the grounding conductor [mm²]
S ≤ 16 mm² S
16 mm² < S ≤ 35 mm² 16 mm²
S > 35 mm² S/2
There is a hexagon bolt with flat and spring washer on the stator frame at the designated
connecting point for the grounding conductor. This is suitable for connecting multi-core
conductors with cable lugs or straps with appropriate conductor ends.
When connecting the grounding conductor, ensure the following:
● The connecting surface is bare and protected against corrosion using a suitable substance,
e.g. acid-free Vaseline, zinc dust primer etc.
● The flat and spring washers are located under the bolt head.
