• Overvoltage and undervoltage protection
Immediately switches off the load output in the case of excessively high
or low battery voltage.
• Overtemperature protection
If the temperature inside the controller becomes too high, then the
controller load output is switched off to reduce the power loss.
• Load output overload protection
If the permissible load current is exceeded, then the load output is
switched off.
• Overvoltage protection
A varistor at the module input provides protection against overvoltages
> 47 V. The component limits the surge energy to 4.4 joules.
• Deep discharge protection / Overcharging protection Prevents exces-
sive discharging / charging of the battery.
• Conforms to the relevant European CE standards
5 Installation
5.1 Mounting location
Mount the device near to the battery, in the orientation shown below, on a
surface with the following properties:
• stable
• vertical • non-flammable
• level • dry
The battery cable should be as short as possible (1 – 2 m) and have a suffi-
ciently large cross-section to keep losses as low as possible, e.g. 2.5 mm² at
10 A and 2 m; 4 mm² at 20 A and 2 m; 6 mm² at 30 A and 2 m. For correct
functioning of the temperature compensation of the charging voltage, the
same ambient temperature must exist at both the controller and the battery.
If this is not possible for installation reasons, then an external temperature
sensor is available as an optional accessory.
Do not install the controller outside. The device must be mounted protected
from moisture, dripping water, spray, rainwater and direct or indirect heat-
ing, e.g. from direct sunlight.
The device generates heat during normal operation. The rear ventilation
required for cooling the device must not be hindered by the mounting loca-
tion or by installation in an additional casing.
A free space of at least 15 cm on all sides of the device must be provided to
ensure the necessary circulation of air for cooling. The permissible ambient
temperature must be adhered to at the mounting location.

The integrated LC display should be protected from UV radiation (e.g. sun-
light) Long-term exposure to UV radiation can permanently discolour the
LC display.
