Application
The LPI VHS-K10 is designed for installation into the Krone LSA-Plus Series 2* termination system. The LPI VHS-K10
must be installed into disconnect blocks to allow the series impedance elements to be inserted in circuit.
Applications include the protection of data networks used for process control and automation. The LPI VHS-K10 will
protect equipment in data acquisition and will protect ISDN circuits.

 

Installation
To install the LPI VHS-K10 plug into a Krone LSA* disconnect block. Ensure that the module is plugged in as Figure 2.
Make sure that the LPI VHS-K10 is plugged fully into the KRONE* block. The edge of the plastic cover should be level
with the front of the KRONE* block when the module is fully inserted.
The earth connection for the LPI VHS-K10 is derived from the spring clips on each end of the board which engage with
the KRONE* frame upon insertion of the module. The LPI VHS-K10 may be fitted to the KRONE* blocks in either a
standard or PROFIL* type frame. It is absolutely essential that the frame is earthed in accordance with ACA TS009. The
frame must connect to the stations protective earth.
If a PROFIL* frame is used, it is important that earthing clips are fitted to each disconnect block before it is attached to
the frame. These are the KRONE* supplied clips which fit into the ends of the disconnect block, and then engage with
the bars on the PROFIL* frame when the block is fitted into the frame.
