Initialization
After connection the battery modules with “Battery Control” will be automatically recognized
as long as the “C+/C-” control line for communication between the modules is connected with
the correct polarity.
12 V operation
The charge and control unit is suitable for rated voltages of 12 V as well as 24 V (factory
default setting). In order to activate 12 V operation, connection to the UPS-Control Software
is required. 12 V operation for the connected device must first be activated via UPS-Control.
The setting options for activation can be found in the “Parameters” tab under “Advanced
Settings”.
A separate 12 V battery module is required for 12 V operation. The 24 V battery modules
cannot be used in this mode.
Note:
In order for the battery modules to be optimally supplied, operation with connected control
lines and battery modules with “Battery Control” is recommended. Attention should be paid
to the polarity.
Before the module is supplied with power, the battery modules should be completely con-
nected in order to prevent false signaling.

Operating Statuses /Signaling
The charge and control unit can signal current operating statuses, warnings and malfunctions.
There are three control lights (LEDs) available for function monitoring as well as three poten-
tial-free contacts.
At the time of delivery the signal outputs are configured as follows:

The charge and control unit is capable of detecting multiple events that can be linked individ-
ually with the three signal outputs via the configuration and management software. The logic
(inverted / not inverted and/or low-impedance / high-impedance) can also be changed if
necessary.
