7. Connect digital inputs
DANGER
The digital inputs are not allowed to be powered when
installing and/or wiring Sensformer Connectivity Device.
Risk of electric shock!
REQUIREMENT
Do not use cables without ferrules. The ferrules must be
certified.
For more information,
requirements chapter.
REQUIREMENT
The using cables on the digital inputs must be double insulated
and must have UL 94 V-1 flammability classification and VW-1
flame rating.

NOTE
Though, the digital inputs are interchangeable, the measured
values are not in DC mode. Because of that, the recommended
wiring is the following: the D2B and D1B are the negative, the
D2A and D1A are the positive in DC mode.
This has no effect to the AC mode.
