WARNING
2.3.2.1 Open-circuit principle (fail-secure)
Without operating voltage, the outside and inside lever handles are decou-
pled (open-circuit principle).
By applying operating voltage (e.g. via a switch), outside and inside lever
handles can be decoupled.
Alternatively, it is always possible to couple the outside and inside lever
handles through the built-in locking cylinder (key).
