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.

* At least 6 A are always available for the charging
process. If the calculated reduced charge current is
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.
