3.3 Installation, electric
Warning
Danger of short circuit! If one of the electrical inputs
6
is supplied with voltage,
there will be voltage at all electrical inputs, because the positive and negative
lines are connected together inside the component.
Ensure that the electrical inputs
6
share a common voltage source.
Otherwise the DRRD may be irreparably damaged by large compensating
currents.
Leave the cover caps on the unused plugs
6
.
The plugs
6
on the side of the housing are not protected in any other way
against accidental contact.
