Operating manual HVL 120-0.3 

 

Area of application for the low voltage limiter 

 

Protection of personnel

 

Protection of equipment

 

At all locations where dangers can occur from the 
rail potential 
On fully-conductive or semi-conductive components 
which are not part of the operating electrical circuit 
and which are located in the area of the overhead 
line or current collector and which are not earthed 
On parts which can become live in the event of a 
fault 

As overvoltage protection 

On further high-current systems, telecommunications and other electrical systems which are at risk, or 
which could be at risk, from the railway’s electrical power supply 

 
 

3  TRANSPORT AND STORAGE 

The low voltage limiter is supplied ex works, packed in a cardboard box. The accessories (fixing brackets, 
fixing bolts and tension washers) are supplied separately from the low voltage limiter. Each consignment is 
accompanied by final inspection record.

Following delivery, each consignment must be checked for completeness and correctness (compare against 
the order and delivery documents). In the case of incompleteness or deviations from the delivery documents, 
the supplier and the carrier must be notified immediately. 
 
The supplied goods must be examined for transport damage immediately on receipt. In the event of 
transport damage, this must be reported immediately to the insurance agent, the carrier and the supplier, 
and a damage report must be completed. Low voltage limiters which show any signs of damage must not be 
installed in the system or be put into service. 
 
The supplied equipment must be stored in a well-ventilated room and must be protected from dirt or 
damage. The original transport package can be used for storage purposes.
