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 91).
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.
