Safety Regulations and Appropriate Application: 

The charger has been designed according to the valid safety regulations. 

  

Appropriate application is restricted to: 

 

1.

 

Charging of lead-gel, lead-AGM, lead-acid or LiFePO4 complete batteries (with integrated BMS, balancing, 
safety circuit and approval!)  Charging of batteries of the indicated nominal voltage and simultaneous 
supply of the consumers being connected to these batteries in fixed installed systems with the indicated 
battery capacities and charging programs. 

2.

 

Connection to a shock-proof socket, which has been installed according to the valid technical regulations, 
protected with max. 16 A (if required mobile/stationary with a fault current breaker (FI) with a nominal 
residual current of 30 mA). 

3.

 

Connection in consideration of the indicated cable cross-sections at the charging ports. 

4.

 

Fuses of the indicated capacity are to be provided near the battery to protect the cabling between 
battery and charger output.  

5.

 

Technically faultless condition. 

6.

 

Installation in a well-ventilated room, protected from rain, humidity, dust, aggressive battery gases, as 
well as in an environment being free from condensation water. 

 

Never use the unit in locations where the risk of gas or dust explosion exists! 

 

 

Open-air operation of the unit is not allowed.

 

 

Lay the cables in a way, that damages are excluded and observe to fasten them tightly.

 

 

Never lay 12 V (24 V) cables and 230 V mains supply cables into the same cable conduit (empty conduit).

 

 

Check live cables or leads periodically for insulation faults, points of break, as well as loosened or overloaded 
connections and remedy possible defects. 

 

The unit is to be disconnected from any connection prior to execution of electrically welding or work on the 
electric system. 

 

If the user is not able to draw from the manual, which characteristic values are valid for a unit or which 
regulations are to be observed, a specialist is to be consulted. 

 

The user / buyer is responsible for the observation of construction and safety regulations of any kind. 

 

The unit does not contain any parts, which can be replaced by the user.

 Even after withdrawal of the mains 

plug, the unit may be 

extremely live

 for an extended period (particularly in case of failure). 

 

Keep children away from the charger and the batteries. 

 

Observe the safety regulations of the battery manufacturer; deaerate the battery room. 

 

Non-observance may result in injury or material damage. 

 

The warranty period is 36 months from the purchase date (against presentation of the sales slip or invoice). 

 

The warranty will be void in case of any inappropriate utilisation of the unit, if it is used beyond the technical 
specification, in case of improper operation or external intervention. We do not assume any liability for any 
damage resulting hereof. The liability exclusion is extended to any service being executed by third, which has 
not been ordered by us in writing. Service is to be effected exclusively by VOTRONIC Lauterbach.
