4.1 General information for electrical connection

e
As far as the electrical safety is concerned, the protection
against unintentional contact of the connected and therefore
up to e electrically interconnected apparatus and the insulation of the
up to 4 feed cables must be designed for the highest voltage, which
99% (high) can occur in the device.
