• 

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.
