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

O must be fixed by strain relief.
To have easier access to the switch box itself and the routing of
cables the switch box can be lowered (see
7]).
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.
