The terminals X1 and X5 have double (reinforced) insulation according to
EN50178. The protection against accidental contact is ensured without
additional measured being taken.

Danger!
ƒ The terminals X3, X4, X6, X7, X8, X9, X10, X11 have basic
insulation (single isolating distance).
ƒ In the event of a defective isolating distance, protection
against accidental contact can only be guaranteed by taking
external measures such as double insulation.
ƒ If an external DC 24 V voltage source is used, the insulation
degree of the controller depends on the insulation degree of
the voltage source.
