External enabling contact
Operating mode / Stand-By
In addition to being operated with
the controller, the unit can be
switched on (normal operation)
and switched off (stand-by) via
an external potential-free contact
(normally-closed).
The contact is equipped with a
wire jumper in the factory. The unit
is enabled in this condition.
If the contact is opened, the unit is
disabled and OFF is shown on the
display.

The connection of a general alarm
signal, for example, for signalling
or for further processing to a BMS
is possible as standard equipment.

tion. As soon as a fault is diag-
nosed on the unit, 230V is present
on the respective terminals of the
alarm contact.
