Configuration
The reduced charging current, which is applied
when the switching contact at the downgrade input
is energised, can be set via DIP switches 4 and 5
on bank S2. The charging current is reduced on a
percentage basis depending on the set maximum
charging current.

less than 6 A, it is rounded up.
6.2.2 Authorisation via the enable input
The tasks described in this section may only
be carried out by a qualified electrician.
The product contains an enable input for author-
ising the charging process. A switching contact
must be installed externally and connected to the
enable input for this purpose. The switching contact
can be a key switch (continuous signal) or a push-
button (pulse signal), for example.
Continuous signal (default setting):
Switching contact
status
open
closed
Pulse signal:
The authorisation is released or terminated by
briefly activating the release input of the switching
contact. To change the setting from continuous sig-
nal to pulse signal, the configuration tool is re-
quired.
