If  the  switch  box  is  lowered  in  service  position  while  the  electrical  installation  is
done, additional cable length has to be taken into account adequately. The cable
routing in normal position is longer than in service position.

All cables which will be connected to the switch box of the ECH

2

O must be fixed by

strain relief.
