For 2 pcs of 7-Core Cable 

Secondary cables are connected directly to the output terminals of the output contactor. Those are designed for M10 bolts. Should you require connecting more than two conductors per terminal (for instance in case of 2 parallel 7-core cables), extension terminals can be mounted on the
terminals of the contactor.
The terminals enable the connection of up to 4-cable shoes dedicated for M8 bolts.
Maximal allowable width of the cable lugs is 17 mm.
