Warning!
The two-wire or multiple-wire cable between the devices
must comply with the insulation voltage requirement
which is stipulated for the installation environment.
Otherwise, a fault (ground fault, short-circuit) may lead to
the destruction of the units or injury to persons.
A cable such as NYM-0 with a rated operational voltage of
U
e
= 300/500 V AC is normally sufficient.
